Question

1. Na + H2O → NaOH + H2​

Answer 1

Answer:

Balanced equation: 2Na+2H2O→2NaOH+H2

A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge are the same for both the reactants and the products. In other words, the mass and the charge are balanced on both sides of the reaction.

Answer 2

Answer:i cannot babe balanced

Explanation:as if we add 2 to hydrogen on either side in NaOH it will get 4 and if we keep doing it, it will end nowhere so therefore it cannot be balanced.
