Question

out of three element p q and R P is less reactive than q and R is more reactive than p and q both suggest an activity to arrange the p q and R in the order of their decreasing reactivity

Answer 1

The reactivity of the metals can be arranged in the following way by noting the conditions:

R>Q>P

R is more reactive than Q , which is more reactive than P.

The reactivity order of these metals can be determined experimentally by the following methods:

1. Metal displacement reactions- involving reaction between metal and salt solution.

2. Metal reaction with Hydrochloric acid( HCl).

3. Metal reactivity with water.

4. Heating the respective metal carbonates.
