Question

2H, +0,-> 2H,0
How many hydrogen atoms are on the left side of the equation?

Answer 1

4

Step-by-step 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 = (4)/(2)`

x= 2

Therefore, 2H2 = 4 hydrogen
