Question

List any two observations when a highly reactive metal is dropped in water

Answer 1

Answer:

Metals are reactive but out of all the two groups of metals, the alkali metal group in the periodic table is highly reactive.

When any metals of this group say sodium is dropped in water heat is produced, and hydrogen gas is released which catches fire.

Answer 2

Two observations when high reactive metal is added to water:

•It produces hydrogen gas (H2).

•The reaction of high reactive metal with water may produce high amount of heat.
