The amount of carbon dioxide gathered when $0.100\,\text{mol}$ of magnesium carbonate reacts with $50.0\,\text{cm}^3$ of $1.00\,\text{mol dm}^{-3}$ sulfuric acid is recorded as time passes. The gas volume is then drawn on a graph against time, producing the line called P. The investigation is carried out again with $0.100\,\text{mol}$ of the same magnesium carbonate, but using another acid sample. All other conditions are kept unchanged. When these readings are plotted, they produce the line called Q. Which acid sample could produce the line called Q?
- A$100\,\text{cm}^3$ of $0.500\,\text{mol dm}^{-3}$ sulfuric acid
- B$100\,\text{cm}^3$ of $1.00\,\text{mol dm}^{-3}$ sulfuric acid
- C$200\,\text{cm}^3$ of $0.500\,\text{mol dm}^{-3}$ hydrochloric acid
- D$200\,\text{cm}^3$ of $1.00\,\text{mol dm}^{-3}$ hydrochloric acid
