Balancing a chemical reaction. Consider the chemical reaction
,
where a, b, c, and d are unknown positive integers. The reaction must be balanced; that is, the number of atoms of each element must be the same before and after the reaction. For example, because the number of oxygen atoms must remain the same,
.
While there are many possible values for and d that balance the reaction, it is customary to use the smallest possible positive integers. Balance this reaction.
