Here is a universal law to balance chemical equations : All chemical equations must be balanced
because of the law of conservation of mass. It states that "matter
cannot be created or destroyed." So, the number of atoms that you
start with at the beginning of the reaction must equal the number
of atoms that you end up with. keeping this law in our mind,lets balance the<span> equation for the reaction of benzene and hydrogen to form cyclohexane. </span><span>C 6 H 6 + H 2 → C 6 H 12. Here is the balance chemical equation. </span><span>2 C 6 H 6 + 6 H 2 → 2 C 6 H 12.</span>
