You have 18 oxygen atoms on one side and (currently) have 6 oxygen atoms on the other.
You can add the coefficient 6 to equal this out!!
Hope this helps :)
<span>Radioisotopes can be used to help understand chemical and biological processes in plants. This is true for two reasons: 1) Radioisotopes are chemically identical with other isotopes of the same element and will be substituted in chemical reactions and 2) Radioactive forms of the element can be easily detected with a Geiger counter or other such device. </span>
