Question

Balancing chemical equations, H2O> H2 +02

Answer 1

Answer:

Q) Balance the chemical equation.

H2O -> H2 + O2

(Sol)->

2 H2O -> 2 H2 + O2

There are same number of atoms of hydrogen and oxygen in reactants as well as the products. Hence the equation is now balanced.

Answer 2

Answer:

H20= H2 +O2

LHS. RHS

H= 2. H=2

O= 1. O= 2

to balance an equation we need to balance the number of molecules on both the sides.

2 H2O = 2 H2+ O2

LHS. RHS

H=4. H=4

O=2. O=2

Hence balanced, 2H20=2H2+O2
