Answer:
When zinc reacts with hydrochloric acid, the reaction bubbles vigorously as hydrogen gas is produced. The production of a gas is also an indication that a chemical reaction is occurring. Zinc reacting with hydrochloric acid produces bubbles of hydrogen gas.

Answer:
The rate of reaction increases in the case of zinc dust compared to the zinc granules, because of increase in surface area as increase in surface are increases the rate of reaction. Thus, when zinc dust is used in the place of zinc granules, hydrogen gas is produced at a faster rate.
