What volume of $0.1 \, M \, H_2SO_4$ is required to completely neutralize $40 \, mL$ of $0.2 \, M \, NaOH$?

The combustion of methane is represented by the following equation: $CH_4(g) + 2O_2(g) \rightarrow CO_2(g) + 2H_2O(l); \Delta H = -890 \, kJ \, mol^{-1}$. How many grams of carbon dioxide are produced when $445 \, kJ$ of heat is released?
