4 HCI + O2 —> 2 H2O + 2 CH2
How many moles of H2O can be produced from 30. moles of HCI?

15 mol

Explanation:

                                   4 HCI + O2 —> 2 H2O + 2 Cl2

from reaction             4 mol                  2 mol

given                          30 mol                x

x = 30 *2/4 = 15 mol
