Hydrogen gas is colorless, odorless, and highly flammable. You can safely test for small quantities of hydrogen like those collected in Experiments 1 and 2 by placing a burning
wooden splint near the opening of a gas collection tube. The positive result is a squeaky
pop sound as hydrogen reacts with oxygen in a small explosion. Given the following
balanced chemical equation for the "pop test", how many moles of O2 will react with 12
moles of hydrogen?
2H2 + O2 → 2H2O
A
3 mol
B
6 mol
С
12 mol
D
24 mol
