Which of the following is the correctly balanced equation for the reaction of hydrogen and oxygen to form water? H_(2)+O_(2)arrow H_(2)O 2H_(2)+O_(2)arrow 2H_(2)O

The correctly balanced equation for the reaction of hydrogen and oxygen to form water is:<br /><br />$2H_{2}+O_{2}\rightarrow 2H_{2}O$<br /><br />In this balanced equation, there are 4 hydrogen atoms and 2 oxygen atoms on both sides of the equation, which satisfies the law of conservation of mass.
