Question 22 (2.5 points)
Based on the following balanced equation, how many moles of H2O can form from the reaction of 6 moles of
CHA?
CH4 (g) + 2 O2 (g) → CO2 (g) + 2 H20 (g)
12
a) 3
15
b) 18
o
18
c) 6
d) 12
21

d) 12

Explanation:

Given data:

Moles of CH₄ react = 6 mole

Moles of water formed = ?

Solution:

CH₄ + 2O₂      →   CO₂ + 2H₂O

Now we will compare the moles of CH₄ with water.

                 CH₄           :          H₂O

                   1              :            2

                  6              :          2/1×6 = 12 moles

Thus from 6 moles of CH₄ 12 moles of water produced.
