Answer: 7.2418 x 10^-19 joules
Explanation:
1 eV equals 1.602 x 10^-19 joules
Then 4.52eV will be multiplied by the above value to give 7.2418 x 10^-19 joules which is the energy required to dissociate the hydrogen molecule
The correct answer would be equation 4, because there are 4 Hydrogens and 2 Oxygens on each side of the equation making it balanced.
