The missing part of the equation is found to be 4/2He. Option A
<h3>What are nuclear equations?</h3>
The term nuclear equations have to do with the type of equation in which one type of nucleus is transformed into another sometimes by the bombardment or loss of a particle.
Now the full equation ought to be written as 7/3Li + 1/1H -----> 4/2He + 4/2He. This is because the total mass on the left is 8 and the total charge on the left is 4.

Molar mass of ethanol is: 46 grams/moles
C2H6O-> 2x12 + 6x1+ 16x1 (see periodic table)
If 46 g correspond to 1 mol, how much moles correspond 35 g?
46g ====1mol
35g====x
x= 35/46
x=0,76 mol
-1367 kj/mol, means that there are -1367 kj in one mol
1mol ==== -1367 kj
0,76mol==== x
x=- 1040Kj
Ethanol released 1040 Kj.
