Answer 2

Calculation of Methane Volume Consumed in the Chemical Reaction

To calculate the volume of methane consumed in the chemical reaction, we can use the stoichiometry of the reaction. The balanced chemical equation for the combustion of methane is:

CH4 + 2O2 → CO2 + 2H2O

From the balanced equation, we can see that 1 mole of methane reacts with 2 moles of oxygen to produce 1 mole of carbon dioxide and 2 moles of water. Therefore, the stoichiometric ratio of methane to carbon dioxide is 1:1.

Given that 74 L of carbon dioxide was produced, we can calculate the volume of methane consumed using the stoichiometric ratio.

Using the stoichiometric ratio, the volume of methane consumed can be calculated as follows:

Volume of methane consumed = Volume of carbon dioxide produced = 74 L

Therefore, the volume of methane consumed during this chemical reaction is 74 liters.

I hope this helps! If you have any further questions, feel free to ask.
