The reason nonmetals are electrical insulator is since
valence shells in nonmetal atoms are almost full, the atoms attract electrons
and hold them tightly to fill their valence. The reason why it acts as an
insulator is the high ionization energy it has. It prevents any electron from
leaving an atom easily even when an electric field is applied.
Answer:
11690J
Explanation:
Use formula Q = mL
where:
Q = Energy (J)
m = Mass (g)
L = Latent heat of fusion for water (J/g) = 344J/g
Therefore:
Q = 35.0 x 344
Q = 11690J
