If there is enough energy and H2, then how many moles of Sn02 will react with 2 moles of H2 and produce 1 mole of Sn and 2 moles of H2O? How many moles of SnO2 does this balanced equation represent?

One mole of SnO2

Explanation:

SnO2(s) + 2H2(g) > Sn(s) + 2H2O(l)

In every question that has to do with stoichiometry, the balanced reaction equation is the first step towards obtaining the correct answer because it serves as a guide in solving the question.

From the balanced reaction equation, we have

1 mole of SnO2 reacts with 2 moles of hydrogen gas to yield two moles of water.

The balanced reaction equation represents one mole of SnO2.

Hence the answer.

the reaction mixture contains some ammonia, plus a lot of unreacted nitrogen and hydrogen. the mixture is cooled and compressed, causing the ammonia gas to condense into a liquid. the liquefied ammonia is separated and removed. the unreacted nitrogen and hydrogen are then recycled back into the reactor .
