Under certain circumstances, carbon dioxide, CO2(g), can be made to react with hydrogen gas, H2(g), to produce methane, CH4(g), and water vapor, H2O(g): CO2(g)+4H2(g)→CH4(g)+2H2O(g) How many moles of hydrogen gas would be needed to react with excess carbon dioxide to produce 53.6 moles of water vapor? Express your answer with the appropriate units. For example, write the unit moles as mol.

5. (10 pts) Helena compares oxidation with reduction. Match each term with the correct definition a) Oxidation • Gain of oxygen • Gain of hydrogen b) Reduction • Loss of electron • Decrease in oxidation number • Gain of electron 6. Jasmine finds that the carbohydrate is one of the major sources of energy of our body. The combustion of the carbohydrate glucose produces carbon dioxide and water: C6H12O6 + O2 CO2 + H2O (unbalanced) a) (2...
Question 8 10 pts Methane gas reacts with water vapor to produce a mixture of carbon monoxide and hydrogen, according to the balanced equation below.

Ethylene oxide is produced by the catalytic oxidation of ethylene: 2C2H4 + O2 → 2C2H4O An undesired competing reaction is the combustion of ethylene: C2H4 + 3O2 → 2CO2 + 2H2O The feed to the reactor (not the fresh feed to the process) consists of 3.00 moles of ethylene per mole of oxygen. The single-pass conversion of ethylene to either ethylene oxide or carbon dioxide is 20.0%, and for every 100.0 moles of ethylene consumed in the reactor, 85.0 moles...
