Byron · Answer 1

5 molecules of water are formed.

1 Oxygen atom is left over.

Explanation:

Hydrogen reacts with oxygen to form water.

H₂ + O₂ - H₂O

We need to balance the above equation. On balancing we get,

2H₂ + O₂ - 2H₂O

When 3 O₂ molecule reacts with 5H₂O, then the equation becomes

5H₂ + 3O₂ - 5H₂O + O

5 molecules of water are formed.

1 Oxygen atom is left over.
