H_{2} + O_{2} -> H_{2}O 2H_{2} + O_{2} -> 2H_{2}O 4H + O_{2} -> 2H_{2}O H_{2} + O -> H_{2}O
I am hesitating between 4 options to answer the following question, which option should I choose?
Question: Which equation is correctly balanced for hydrogen and oxygen reacting to form water?
Possibilities:
- H_{2} + O_{2} -> H_{2}O
- 2H_{2} + O_{2} -> 2H_{2}O
- 4H + O_{2} -> 2H_{2}O
- H_{2} + O -> H_{2}O

2H_{2} + O_{2} -> 2H_{2}O
