write correct state, balance, and type of reaction for Zn(s)+Li+(aq) and nitric acid+sodium bicarbonate

Question

Question

Answer 1

Answer #1

1)

Zn2+(aq) + 2Li(s) ----> 2Li+(aq) + Zn(s)

This is a redox reaction as Li is reducing agent and Zn is oxidizing agent. Li gets oxidized and Zn gets reduced.

2)

HNO3(aq) + NaHCO3(aq) ----> NaNO3(aq) + CO2(g) + H2O(l)

Gas evolution reaction.
