Think about it like this, the more mass there is, the faster its going to go. If you took a golf ball and a ping pong ball and you held them each separately, you would notice that the golf ball is heavier.

Explanation:
The reaction between hydrogen and oxygen gives water (H2O)
2H,+O, -> 2H2O
Oxygen is a gas O, = O2
Balancing both sides
let , be x
2x = 4

x= 2
Therefore, 2H2 = 4 hydrogen
