The nuclear equation is incomplete.
What particle completes the equation?

Answer:
[tex]_{6}^{12} C[/tex]
Explanation:
[tex]_{1}^{1}H+_{7}^{15}N ---> _{6}^{12} C+ _{2}^{4}He[/tex]
1+7 = 6+2 =8 -protons
1+15 = 12+4 = 16 - protons +neutrons
Answer: C
Explanation: 1+7 = 6+2 =8 -protons
1+15 = 12+4 = 16 - protons +neutrons
