Which statement is true about this reaction? (}_{7)^14N+_(1)^1Harrow _(8)^15O It is a practical source of energy on Earth. II occurs only outside the solar system. Its product is heavier than each of its reactants. It shows the critical mass of an element.

The correct statement about the given reaction is:**Its product is heavier than each of its reactants.**In this nuclear reaction, nitrogen-14 ( ) reacts with hydrogen-1 ( ) to produce oxygen-15 ( ). The product, oxygen-15, has a mass number (15) that is greater than the mass numbers of the reactants (14 for nitrogen-14 and 1 for hydrogen-1). Therefore, the product is indeed heavier than each of its reactants.
