Which represents a balanced chemical equation?

co(2) + 2h(2)0 → 2ch(4) + 20(2)
ch(4) + o(2) → co(2) + h(2)o
ch(4) + 20(2) → co(2) + 2h(2)o
co(2) + h(2)o → ch(4) + o(2)

The answer to your question is the third one

Explanation:

Check which reaction is balanced

a) CO₂ + 2H₂0 → 2CH₄ + 20₂

Reactants Products

1 C 2

4 H 8

4 O 4

This reaction is unbalanced because the number of reactants is different from the number of products.

b) CH₄ + O₂ → CO₂ + H₂O

Reactants Products

1 C 1

4 H 2

2 O 3

This reaction is unbalanced because the number of reactants is different from the number of products.

c) CH₄ + 20₂ → CO₂ + 2H₂O

Reactants Products

1 C 1

4 H 4

4 O 4

This reaction is balanced because the number of reactants is equal to the number of products.

d) CO₂ + H₂O → CH₄ + O₂

Reactants Products

1 C 1

2 H 4

3 O 2

This reaction is unbalanced because the number of reactants is different from the number of products.
