Question

What is the balanced equation for the production of water?

Answer 1

H₂ + O₂ → H₂O

Now, check that oxygen has two atoms on the left and one on the right

so, you put 2 on the right side

H₂ + O₂ → 2H₂O

oxygen is balanced so, add 2 on H₂ to balance out hydrogen

THE FINAL BALANCED EQUATION:

2H₂ + O₂ → 2H₂O
