Question

Methane, the chief component of natural gas, burns in oxygen according to the equation

CH4(g) + 2 O2(g) -----> CO2(g) + 2 H2O(g)
If 7.0 mol of CH4 react with an unlimited amount of oxygen, what amount (in moles) of H2O(g) will be produced?

please show your work!

Answer 1

14

Explanation:

From the equation, we see that 1 mol of methane produces 2 moles of water. To find the amount of water produced if 7.0 moles of methane react, we use the following proportion:

1 mol of methane / 7 moles of methane = 2 moles of water / x moles of water

x = 7*2 = 14 moles of water
