A research team is testing the combustion reaction of methane with oxygen. The balanced chemical equation is CH4 + 2O2 → CO2 + 2H2O. The team is using an 8.20-liter closed container at 30.0°C. The partial pressure of methane is 130.0 kilopascals, and the partial pressure of oxygen is 142 kilopascals. What is the limiting reactant and the mass of carbon dioxide produced in the combustion reaction?
