The correct answer is E. C6H6 is not soluble in water. This is determined by the polarities of these substances. Benzene is a non-polar substance because it has equal number of electrons sharing a bond thus it does not dissolve in water which is a polar substance.
For future reference, the answer is choice A) The atom is no longer recognizable.

Answer:
I don't understand what to do with this
Answers:
G. -; H. -; I. +
Step-by-step explanation:
ΔE = q + w
Anything going into the system is positive (+), and anything leaving the system is negative (-).
G. Cooling with expansion
q: Heat is leaving; q is -
w: The system is doing work on the surroundings. Energy is leaving the system. w is -.
ΔE is -.
H. Heating a little, expanding a lot
q: Heat is entering; q is +.
w: The system is doing work on the surroundings. Energy is leaving the system. w is -.
However, the expansion work is the major factor.
ΔE ≈ w. ΔE is -.
I. Endothermic, no expansion
q: Heat is entering; q is +.
w: No expansion. w = 0.
ΔE = q. ΔE is +.
