Answer #1

The reactant box contains 4molecules of H2 and two molecules of O2 and the product box contains 4 molecules of water.

Therefre, the final balanced chemical reaction between H2(g) and O2(g) molecules is given by

4 H2(g) + 2O2(g) ----------> 4 H2O(g).

The reduced balanced equation is

2H2(g) + O2(g) ---------> 2H2O(g).
