Question

How many moles of oxygen are necessary to generate 28 moles of water, according to the following equation:

2H2+O2→2H2O

Answer 1

Answer #1

2H2+O2→2H2O

already reaction is balanced

according to balanced reaction

2.0 moles H2O require 1 mole O2

28 moles of H2O require 28 x 1 / 2.0 = 14 moles O2

moles of O2 required = 14

Answer 2
