Methane reacts with oxygen. $\text{CH}_4(\text{g}) + 2\text{O}_2(\text{g}) \rightarrow \text{CO}_2(\text{g}) + 2\text{H}_2\text{O}(\ell)$ $10\,\text{cm}^3$ of methane is mixed with $25\,\text{cm}^3$ of oxygen. What would be the total gas volume measured after the reaction? (Assume all volumes of gases are measured at room temperature and pressure.)
- A$10\,\text{cm}^3$
- B$15\,\text{cm}^3$
- C$30\,\text{cm}^3$
- D$35\,\text{cm}^3$
