question 64

Multiple Choice

One of the fusion reactions that occurs in the sun is:
$${ } _ { 2 } ^ { 3 } \mathrm { He } + { } _ { 2 } ^ { 3 } \mathrm { He } \rightarrow { } _ { 2 } ^ { 4 } \mathrm { He } + { } _ { 1 } ^ { 1 } \mathrm { H } + { } _ { 1 } ^ { 1 } \mathrm { H }$$
The following atomic masses are known:
${ } _ { 1 } ^ { 1 } \mathrm { H } : \quad 1.007825 \mathrm { u }$
${ } _ { 2 } ^ { 3 } \mathrm { He } : \quad 3.016029 \mathrm { u }$
${ } _ { 2 } ^ { 4 } \mathrm { He } : \quad 4.002603 \mathrm { u }$
