what mass CO2 could be formed by the reaction of 16 g CH4 with 32 g of O2
Answers
Answer:
As methane is the only source of carbon in this scenario, we shall start there.
The molar mass of methane is 16.04 grams. If we round it down, that gives us one mole of methane or one mole of carbon (12 grams) and two moles of hydrogen gas.
32 grams of oxygen is one mole. We’d need two moles to fully burn the methane. In other words, if we assume that the methane is either burned completely or not at all, we can determine that half the methane has been burned.
So, half the methane is 6 grams of carbon and 2 grams of hydrogen gas. Each gets half the oxygen (two atoms to form CO2 per two atoms to form 2 H2O) and so increases its mass by 16 grams.
This leaves us with a final score of 22 grams of CO2, 18 grams of H2O and 8 grams of CH4m
