Answer 1

Nano3=na+no2
Zn=zno
Naoh=na+h2o
Hope to helps

Answer 2

Answer: The products formed as sodium zincate, ammonia and water.

Explanation:

Caustic soda is the common name for sodium hydroxide. The chemical formula for this compound is NaOH.

The reaction for sodium nitrate, zinc and sodium hydroxide follows the equation:

$3Zn+NaNO_2+5NaOH\rightarrow 3Na_2ZnO_2+NH_3+H_2O$

By Stoichiometry of the reaction.

3 moles of zinc metal reacts with 1 mole of sodium nitrate and 5 moles of sodium hydroxide to produce 3 moles of sodium zincate, 1 mole of ammonia and 1 mole of water.

The above reaction is a type of redox reaction because here, zinc is getting oxidized from 0 to +2 state and nitrogen is getting reduced from -3 to +3 state.
