Final answer:
To complete the equation, we need to balance the mass numbers and atomic numbers of the elements involved. The type of this equation is a nuclear reaction.
Step-by-step explanation:
The given equation is:
14N + 4He → ??? + 7H
To complete the equation, we need to balance the mass numbers and atomic numbers on both sides. The nuclear symbol for helium-4 is He, with a mass number of 4 and an atomic number of 2.
Therefore, the balanced equation is:
14N + 4He → ??? + 7H
Finally, the type of this equation is a nuclear reaction.
