Find the number of moles of water that can be formed if you have 154 mol of hydrogen gas and 72 mol of oxygen gas.

77

Explanation:

H2O needs 2 hydrogens and you have 154 so 154/2 is 77

thats the most you can do

The answer is 144 mol.

Explanation:

"72 mol of oxygen will form only 144 mol of water, and 10 mol of hydrogen remain in excess, so the limiting reactant is oxygen and hydrogen is in excess."

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
