At room temperature and pressure, which reaction would result in the largest volume of carbon dioxide? [$M_r$: $\text{CaCO}_3$, $100$; $\text{Na}_2\text{CO}_3$, $106$; $\text{CuCO}_3$, $124$]
- Aburning 1 g of carbon in excess oxygen: $\text{C}(s) + \text{O}_2(g) \rightarrow \text{CO}_2(g)$
- Bthermal decomposition of $10\,$g of calcium carbonate in the air: $\text{CaCO}_3(s) \rightarrow \text{CaO}(s) + \text{CO}_2(g)$
- Cadding $10\,$g of sodium carbonate to an excess of dilute hydrochloric acid: $\text{Na}_2\text{CO}_3(s) + 2\text{HCl}(aq) \rightarrow 2\text{NaCl}(aq) + \text{CO}_2(g) + \text{H}_2\text{O}(l)$
- Dadding $50\,\text{cm}^3$ of $1\,\text{mol dm}^{-3}$ sulfuric acid to an excess of copper carbonate: $\text{CuCO}_3(s) + \text{H}_2\text{SO}_4(aq) \rightarrow \text{CuSO}_4(aq) + \text{CO}_2(g) + \text{H}_2\text{O}(l)$
