Answer:
3.2 moles
Explanation:
First, we'll begin by writing a balanced equation for the Combustion of methane to produce carbon dioxide. This is illustrated below:
CH4 + 2O2 —> CO2 + 2H2O
From the balanced equation above,
1 mole of methane (CH4) reacted to produced 1 mole of carbon dioxide (CO2).
Therefore, 3.2 moles of methane (CH4) will react to produce 3.2 moles of carbon dioxide (CO2).
From the illustration above, 3.2 moles of methane is needed to produce 3.2 moles of carbon dioxide.
