In the lab, you are asked to plan an investigation that shows how the structure of substances can explain the strength of the electrical forces between
particles. To show this, you decide to determine how much tinfoil will melt when the heat of different objects touches it. One of the objects you test
releases 5.7 kJ of heat. How much of the tinfoil will melt?
AHjus=7.029 kJ/mol
O
A. 16.99
B. 20.89
C. 84.39
D. 96.39
