The experiment is arranged as shown. Every 30 seconds, the mass of the conical flask and its contents is recorded. Which option correctly describes the reaction and the changes to the reaction conditions?
- AAdding $10\text{ cm}^3$ of water to the $50\text{ cm}^3$ of acid increases the rate of the reaction.
- BIncreasing the size of the pieces of calcium carbonate increases the rate of the reaction.
- CIncreasing the temperature increases the rate of the reaction.
- DThe mass of the conical flask increases as carbon dioxide is formed.
