Based on the diagram below, answer the following for 2 points each: +
-
.
• Use the size and direction of the "energy arrows" to explain whether this
illustration is an exothermic or endothermic reaction.
Explain in terms of atomic bonds how energy is involved in chemical reactions.
Explain how the arrows would be different if the reaction were the other of
the two choices in part one.

One of the hopes for solving the world's energy problem is to make use of the fusion reaction 21h +31h --> 42he + 10n + energy how much energy is released when 1 mol of deuterium is fused with 1 mol of tritium according to the above reaction? the masses of the atoms and the neutrons are as follows: 21h = 2.0140 amu 31h = 3.01605 amu 42he = 4.002603 amu 10n = 1.008665 amu. the speed of light is 2.9979 x 108 m/s.
