Which statement is true about this reaction? 7 to the 14th power cap n plus 1 to the 1th power cap h rightarrow 8 to the 15th power cap o

The reaction combines nitrogen-14 and hydrogen-1 to form oxygen-15. The oxygen nucleus has a mass number of 15, which is greater than the mass number of either individual reactant (14 or 1). So the true statement is that the product is heavier than each reactant; this does not mean it is heavier than the two reactants combined.
