Question

a piece of magnesium is dropped in water molecular, ionic, and net

Answer 1

Magnesium metal reacts with hot water(steam) to form magnesium hydroxide and hydrogen gas.

Molecular :

Mg(s) + 2H₂O(g) $\rightarrow$ Mg(OH)₂(aq) + H₂(g)

Ionic:

Mg(s) + 2H₂O(g) $\rightarrow$ Mg²⁺(aq) + 2 OH^-(aq) + H₂(g)

Net ionic equation:

Mg(s) + 2H₂O(g) $\rightarrow$ Mg²⁺(aq) + 2 OH^-(aq) + H₂(g)

Here there are no spectator ions so ionic equation is same as net ionic equation.
