It takes 770 joules of energy to raise the temperature of 50.0 g of mercury by 110°c. what is the specific heat capacity of mercury?

0.14 J/g°C.

Explanation:

The amount of heat absorbed by Hg = Q = m.c.ΔT.

where, m is the mass of Hg (m = 50.0 g).

c is the specific heat capacity of Hg = ??? J/g°C.

ΔT is the temperature difference = (final T - initial T = 110.0°C).

∴ The amount of heat absorbed by Hg = Q = m.c.ΔT = 770.0 J.

∴ 770.0 J = (50.0 g)(c)(110.0°C).

∴ c = Q/m.ΔT = (770.0 J)/((50.0 g)(110.0°C) = 0.14 J/g°C.

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
