If 26.4 L of H2 reacted with 13.2 L of O2 at STP, what is the volume of the gaseous water collected assuming that none of it condenses?

Answer 1

2H2+O2>>2H2O

according to the balancedequation, it it remains at the same temperature...

every two volumes of H2 reacted to one volume of O2 yields 2 volumes of H2O.

so if one volume = 13.2liters, I bet you get 26.4 liters H2O
