Answer 1

The balanced equation for the reaction of zinc with aqueous HCl is -

When H2 gas is produced, you will observe bubbles in the reaction mixture and you can observe a pop sound if you take a little match near the mouth of the test tube.

This is a displacement (or substitution) reaction.

Mg reacts with oxygen to produce MgO as follows -

$2Mg (s) +O_2(g) \rightarrow 2MgO$

Magnesium oxide forms a bright light when it's burned and in presence of water it forms magnexmag hydroxide.

This is an addition reaction.
