Question

The equation for water is H2 +O2 → H2O. To balance the equation, which coefficient should be placed in front of H2 and H2O?

1
2
3
4

Answer 1

2

Step-by-step explanation:

2H2 + 02 ===> 2H20

Your first job is to balance the oxygens. The left side has 2 and so you must put a 2 in front of the H20.

The H2 and H2O are then balanced.
