Answer 1

Heya....

Zn+NaOH-Na2ZnO2+H2...
i.e. Sodium zincate and hydrogen gas is evolved...

HOPE IT HELPS☺☺

Answer 2

Answer: The equation for the action of zinc metal with base is given below.

Explanation:

Generally metals reacts with alkalies to form salt and hydrogen gas.

When zinc reacts with sodium hydroxide it gives sodium zincate and hydrogen gas a products.

The chemical reaction for the action of zinc metal with NaOH is given by:

$Zn(s)+2NaOH(aq)\rightarrow Na_2ZnO_2(aq)+H_2(g)$

By Stoichiometry of the reaction:

1 mole of zinc metal reacts with 2 moles of sodium hydroxide to produce 1 mole of sodium zincate and hydrogen gas.
