Question

Consider the following reaction:

H2(g) + 2O2(g) --> 2H2O(g)

How many liters of H2O are produced when 15.7 liter of hydrogen are reacted with excess oxygen at STP?

Answer 1

Answer: 15.7 liters

Explanation: reaction is 2H2 + O2. -> 2H2O

Because all substance still are gases, volumes in

STP conditions are proportional to amount of moles.

Amount of water is same as Hydrogen. Also volume is same.
