The Q value of a nuclear reaction, A + b → C + d, is defined by
Q=[mA+mb]−[mC+md]
where, the masses refer to the respective nuclei. Determine from the given data the Q-value of the following reactions and state whether the reactions are exothermic or endothermic.

(i) ₁H¹+₃H¹→₁H²+₁H²
(ii) ₆C¹²+₆C¹²→₁₀Ne²⁰+₂He⁴

Atomic masses are given to be m(₁H²)=2.014102u
m(₃H¹)=3.016049u
m(₆C¹²)=12.000000u
m(₁₀Ne²⁰)=19.992439u
