What is the mass in grams of CuO that would be required to produce 15.50 moles of nitrogen gas in the following chemical reaction?
2 NH3(g) + 3 CuO(s) - 3 Cu(s) + N2(g) + 3 H2O(g)

for points guys

im not exactly sure but i think its b!

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.

answer: cellular respiration takes in food and uses it to create atp, a chemical which the cell uses for energy. usually, this process uses oxygen, and is called aerobic respiration. it has four stages known as glycolysis, link reaction, the krebs cycle, and the electron transport chain.
