Co(OH) 2 clusters have been successfully deposited onto TiO 2 surface via a simple precipitation route. Co(OH) 2 clusters can act as effective co-catalysts to greatly decrease the electron–hole recombination probability and increase the charge carrier lifetime, thus enhancing the photocatalytic H 2 evolution efficiency of TiO 2. Step 4: Substitute Coefficients and Verify Result. Count the number of atoms of each element on each side of the equation and verify that all elements and electrons (if there are charges/ions) are balanced. Co (NO3)2 + 2 NaOH = Co (OH)2 + 2 NaNO3.

You follow a systematic procedure to balance the equation. Start with the unbalanced equation: #"CH"_3"OH" + "O"_2 → "CO"_2 + "H"_2"O"# A method that often works is first to balance everything other than #"O"# and #"H"#, then balance #"O"#, and finally balance #"H"#. Another useful procedure is to start with what looks like the most complicated formula. The most complicated formula looks like #"CH"_3"OH"#. We put a 1 in front of it to remind ourselves that the number is now fixed. We start with #color(red)(1)"CH"_3"OH" + "O"_2 → "CO"_2 + "H"_2"O"# Balance #"C"#: We have #"1 C"# on the left, so we need #"1 C"# on the right. We put a 1 in front of the #"CO"_2#. #color(red)(1)"CH"_3"OH" + "O"_2 → color(blue)(1)"CO"_2 + "H"_2"O"# Balance #"H"#: We can't balance #"O"# because we have two oxygen-containing molecules without coefficients. ∴ Let's balance #"H"# instead. We have #"4 H"# on the left, so we need #"4 H"# on the right. There are already #"2 H"# atoms on the right. We must put a 2 in front of the #"H"_2"O"#. #color(red)(1)"CH"_3"OH" + "O"_2 → color(blue)(1)"CO"_2 + color(orange)(2)"H"_2"O"# Balance #"O"#: We have fixed #"4 O"# on the right and #"1 O"# on the left. We need #"3 O"# on the left. Uh, oh! Fractions! We start over, this time doubling all the coefficients. #color(red)(2)"CH"_3"OH" + "O"_2 → color(blue)(2)"CO"_2 + color(orange)(4)"H"_2"O"# Now we can balance #"O"# by putting a 3 in front of #"O"_2# #color(red)(2)"CH"_3"OH" + color(purple)(3)"O"_2 → color(blue)(2)"CO"_2 + color(orange)(4)"H"_2"O"# Every formula now has a coefficient.

Carbon monoxide and carbon dioxide are two similarly sounding gases with different properties. So what's the difference? The differences between carbon monoxide (CO) and carbon dioxide (CO2) are important, but the gases are often confused. While they may sound the same they are completely different gases with different sources, chemical properties and dangers. The media often adds to this confusion because of their inability to properly identify the two gases. Countless stories are written about CO dangers from CO2 leaks. Other stories are written about the dangers of CO2 and global climate change. A search online for “CO2 detector” will provide results for “CO detectors.” This confusion leads some to assume the gases are both equally bad and dangerous. They are not. But, before we get into how and why they are different, here's a brief understanding of where they each come from. Table of Contents About Carbon DioxideCO2 Facts CO2 Recommended LimitsAbout Carbon Monoxide CO Facts CO Recommended LimitsCO and CO2 – What’s the Same? CO and CO2 – What’s the Difference? Parts per Million vs. Percentage Gas Conclusion About Carbon Dioxide Carbon dioxide (CO2) is a colorless, odorless and tasteless gas. It is nonflammable at room temperature. The linear molecule of a carbon atom that is doubly bonded to two oxygen atoms, O=C=O. Where does Carbon Dioxide come from? It is a naturally occurring gas in earths atmosphere naturally produced by the decomposition of plant and animal life as well as respiration, which takes in oxygen and exhales CO2. Plants and trees depend on CO2 for life (they take in CO2 and give out oxygen). Carbon dioxide can also be produced through industrial processes. For instance, industrial plants that produce hydrogen or ammonia from natural gases, are some of the largest commercial producers of carbon dioxide. Carbon dioxide as a solid, is also known as "dry ice" as it coverts directly from a solid to a gas at -78°C or above. While not as deadly as carbon monoxide, carbon dioxide can affect your health both directly and indirectly. The direct effect is simple: too much carbon dioxide in an enclosed space – for example, in a submarine – can suffocate you long before the oxygen runs out. Think this can’t happen to you? Actually, dozens of people die every year as the result of leaky CO2 storage tanks attached to soda machines in bars and restaurants or in unventilated keg coolers when a beer line is left open. Others die in dry ice (frozen carbon dioxide) storage lockers used for temporary food storage. For protection from CO2 in enclosed spaces, CO2Meter offers CO2 safety alarms. CO2 Facts CO2 is a common gas in the atmosphere and is required for plant life CO2 is a natural byproduct of human and animal respiration, fermentation, chemical reactions, and the decomposition of plant and animal life. In the atmosphere CO2 measures approximately 400 ppm (parts per million). CO2 is non-flammable, with no explosive properties CO2 poisoning is rare; however scuba divers have to watch out for it (the bends) Leaking pressurized CO2 tanks in enclosed areas can be dangerous for occupants - both from high levels of CO2 and from lower levels of oxygen (O2 displacement / Asphyxiation). CO2 Recommended Limits 410 ppm is the current average CO2 level on the planet ASHRAE recommends a 1,000 ppm limit for office buildings and classrooms to ensure overall health and performance OSHA limits workplace exposure levels to 5,000 ppm time-weighted average (over 8 hours) Drowsiness can occur at 10,000 ppm (1%) – common in closed cars or auditoriums Symptoms of mild CO2 poisoning include headaches and dizziness at concentrations less than 30,000 ppm (3%) At 40,000 ppm (4%) CO2 can be life-threatening About Carbon Monoxide Like carbon dioxide, carbon monoxide is also a colorless, odorless, and tasteless gas - that is toxic and has the molecular formula CO. Many refer to carbon monoxide (CO) as one of the most dangerous gases. Where does carbon monoxide come from? Many refer to carbon monoxide as the result of "incomplete combustion". This happens, when there is a limited supply of air and only half as much oxygen adds to the carbon. Not normally occurring in nature, is a commercially important chemical, and is the result of oxygen-starved combustion from improperly ventilated fuel-burning motors and appliances like: Oil and gas furnaces Gas water heaters or gas ovens Gas or kerosene space heaters Fire places and wood stoves Portable generators Older autos without catalytic converters Too much carbon monoxide in an unventilated space is deadly. In fact, carbon monoxide poisoning is the most common type of fatal poisoning worldwide. This is why many new homes are built with CO detectors in addition to smoke detectors. For protection against CO poisoning CO2Meter offers CO safety Monitors. CO Facts CO is almost entirely a man-made gas that is not normally found in the earth's atmosphere. CO is produced at dangerous levels by oxygen-starved combustion in improperly ventilated fuel-burning appliances such as generators, oil and gas furnaces, gas water heaters, gas ovens, gas or kerosene space heaters, fireplaces, and stoves The highest CO emissions are produced by internal combustion engines without a catalytic converter. CO can be a flammable gas in higher concentrations (sometimes referred to as C1D1 or C2D2 environments). Devices to measure carbon monoxide in these concentrations are often designed to be explosion-proof. CO is the most common type of fatal poisoning in the world. CO Recommended Limits Symptoms of mild CO poisoning include headaches, dizziness, and violent vomiting at concentrations less than 100 ppm ppm is the current average CO level on the planet 9-50 ppm is the standard maximum limit for an 8-hour workday 200-400ppm will result in physical symptoms followed by unconsciousness and death within hours Concentrations above 800 ppm can be life-threatening in minutes Both are made from carbon and oxygen molecules Both are colorless, tasteless and odorless gases Both are in the air we breath (albeit in different concentrations) Both are released during combustion Both are important industrial gases Both are potentially deadly and can cause severe health problems While they both have the word "carbon" in their name, -monoxide (mono in Greek means 1) refers to the bond between a single carbon molecule and a single oxygen molecule while -dioxide (di in Greek means 2) refers to the bond between a single carbon molecule and two oxygen molecules, (oxide means a simple compound of oxygen). In other words, CO is C+O while CO2 is O+C+O. Both carbon dioxide and carbon monoxide are colorless, odorless and tasteless gases. However, some describe the odor of high levels of CO2 as “acidic” or “bitter.” While both CO and CO2 are potentially deadly, this happens at vastly different concentrations. While 35 ppm ( of CO is quickly life threatening, it takes more than 30,000 ppm (3%) of CO2 to reach the same risk level. Compressed carbon dioxide and carbon monoxide are both important industrial gases. For example, CO2 is used to carbonate beverages and to increase plant growth in indoor greenhouses. CO is used during the manufacturing of iron and nickel as well as the production of methanol. In spite of their molecular similarity, they both behave very differently when interacting with other molecules. CO and CO2 – What’s the difference? The most important difference is that carbon dioxide is a common, naturally occurring gas required for plant and animal life. CO is not common. It is a byproduct of the burning of fossil fuels such as oil, coal, and gas. CO poisoning occurs when carbon monoxide builds up in your bloodstream. Your body replaces the oxygen in your red blood cells with carbon monoxide. leading to serious tissue damage. CO2 poisoning occurs when the lungs cannot take in enough oxygen. CO2 does not undergo oxidation reactions and is a non-flammable gas. CO undergoes oxidation reactions and is therefore a flammable gas. CO2 has a molar mass of about 44g/mol. CO2 has a molar mass of about 28g/mol. Another general difference is the number of carbon and oxygen atoms. Carbon Monoxide contains one carbon and one oxygen atom, whereas carbon dioxide contains one carbon and two oxygen atoms. Carbon Dioxide vs. Carbon Monoxide Applications Both carbon dioxide and carbon monoxide can be found commonly used throughout many various applications and industries. Below, we highlight the main applications the gases can be found in. Indoor Agriculture Carbon dioxide is often used by plants in the process of photosynthesis, making the gas vital in areas of indoor agriculture, cultivation, hydroponics, and vegetable farming. Restaurant and Beverage One common area and use of CO2 is in restaurants or beverage applications, where CO2 is used in fountain soda systems or when crafting beer. The gas is used to carbonate drinks and while vital, can be deadly at high concentrations - making the need of CO2 monitoring, critical. Indoor Air Quality Both carbon dioxide and carbon monoxide are commonly found in indoor air quality (IAQ) environments. Carbon dioxide can often be used as indicator of the adequacy of ventilation systems. When windows or buildings are closed, the need for ventilation is vital for improving health and gaining fresh air intake for heating/cooling systems. Carbon monoxide is built up from fuel-burning appliances and devices. The need to monitor CO in your home is vital in order to alert individuals if the gas is poisonous or above normal threshold anywhere in your home. Industrial Process Carbon monoxide is commonly used in industrial processes such as production of aldehydes, or as a reducing agent to convert naturally occurring oxides of metal to pure. Carbon dioxide can be found in industrial processes and used as a refrigerant (dry ice), blasting coal, or in fire extinguishers. Understanding PPM - parts per million While large gas concentrations in a volume of air are measured in percentages, small volumes are measured in parts-per-million or parts per million (ppm) by volume (ppmv). When measuring small volumes, the range of concentrations is from 0 to 1,000,000, which equals 0-100%. Every 10,000 ppm equals 1% concentration. For example, instead of saying "1% gas by volume," scientists will say "10,000 ppm." This is because 10,000 / 1,000,000 = 1%. Why use ppm? This is because it is easier to write that the CO2 level in a room has risen from 400 ppm to 859 ppm than to explain that the CO2 level has risen from to However, both are correct. Conversely, when measuring gases above 10,000ppm it is simpler to write 1%. Read more about parts-per-million here. Using gas detectors to measure CO vs. CO2 Regardless of what industry you work in, leaks and overexposure to both gases can occur around you each and every day. Recently publicized fatalities involving both CO2 and CO have refocused attention on the need to accurately and effectively detect and monitor for the presence of gases. Understanding the gases and being able to prevent potential injuries and hazards from occurring is the best preventive first step you can take. When it comes to choosing the right gas detector for the workplace, a single-gas CO detector will not measure CO2 levels, and vice-versa. Gas detectors are built from a specific sensing technology and principle which is specific for being able to measure each gas. The bright side is that there are a few options when it comes to the best gas detectors for carbon monoxide or carbon dioxide. The most important factor is that you can understand the environment that you are measuring and know what gas you will need to be monitoring.

When they get a little complicated, I like to break them up into half reactions. Co(OH)2 ==> Co(OH)3 . It's obvious that Co changes from +2 to +3 so we need a one electron on the right and we need to balance the OH^- which we can do directly. Co(OH)2 + OH^- ==> Co(OH)3 + e Note that the equation balances a. elements. b. electron change. c. charge. Next half cell. O2^-2 ==> OH^- First we place a 2 coefficient for OH^- and compute changes. O2^-2 ==> 2OH^- Now O2^-2 has changed from -2 on the left (for both oxygens) to -4 on the right (for both oxygens) (which is why I stuck that two before starting any of this--we must compare the same number of oxygen atoms). So the change in electrons is -2 to -4 or +2; O2^-2 + 2e ==> 2OH^- The charge on the left is -2, on the right is -4 so we must add 2OH^- to the right. O2^-2 + 2e ==> 4OH^- and add water to the left. 2H2O + O2^-2 + 2e ==> 4OH^- a. by atoms. yes. b. by electron change. yes. c. by charge. yes. Now note the first half reaction changes by 1 e, the second half reaction by 2e; therefore, we multiply the first one by 2 and second one by 1 and add. You should do this but you should get this. 2Co(OH)2 + 2OH^- + O2^-2 + 2H2O ==>2Co(OH)3 + 4OH^- We can cancel 2OH&- to make it 2Co(OH)2 + O2^-2 + 2H2O ==>2Co(OH)3 + 2OH^- Now we can add Na^+ to the left for the Na2O2 and the right for the NaOH in the problem. 2Co(OH)2 + Na2O2 + 2H2O ==> 2Co(OH)3 + 2NaOH Cobalt(II) hydroxide react with oxygen 4Co(OH)2 + O2 4CoO(OH) + 2H2O [ Check the balance ] Cobalt(II) hydroxide react with oxygen to produce cobalt metahydroxide and water. This reaction takes place at a temperature near 100°C and an overpressure.
