Hi. I am not sure how to balance this equation. Could someone help? Thanks!?

Question

Procedure #3 Summarize what happened in this reaction by placing the number of each molecule reacted or formed in fron of its formula. Balance the following equation.

__H2 + __ O2 ==> __ H2O

Answer 1

2 H2 + O2 ==> 2H2O

Answer 2

The best way to look at this problem is to count the number of Hydrogen and Oxygen on each side

H2 + 02 => H2O

So we have 2H + 2O = 2H + 1O

Seeing as how we don't have enough O on the right side we will need to double it.

H2 + O2 =>2H2O

So we have 2H + 2O = 4H + 2O

Seeing as how we don't have enough H on the left side we will need to increase it.

2H2 = O2 => 2H20

So we have 4H + 2O = 4H + 2O

Now that they are equal we are done.

Answer 3

hey it is 2H2+O2==>2H20

PLEASE vote me for this

Answer 4

2H2 + O2 >> 2H2O

Answer 5

2H2 +  O2 ==> 2H2O
