Excess magnesium was added to a beaker of aqueous hydrochloric acid on a balance. A graph of the mass of the beaker and contents was plotted against time (line 1).
What change in the experiment could give line 2?
- The same mass of magnesium but in smaller pieces
- The same volume of a more concentrated solution of hydrochloric acid
- A lower temperature
Original question:
The answer is just II. However, I thought that both I and II would answer the question. Why is it just II?
