Which chemical equation below shows a balanced reaction that follows the law of conservation of matter?(1 point)

Responses

H2 + O2 → H2O
H 2 + O 2 → H 2 O

2H2 +O2 → 2H2O
2H 2 +O 2 → 2H 2 O

H2 + O2 → 2H2O
H 2 + O 2 → 2H 2 O

2H2 + 2O2 → 2H2O

1 answer

The correct balanced chemical equation that follows the law of conservation of matter is:

2H2 + O2 → 2H2O

This equation shows that two molecules of hydrogen (H2) react with one molecule of oxygen (O2) to produce two molecules of water (H2O), with the number of atoms of each element being the same on both sides of the equation.
