It takes 2,267 joules of heat to raise the temperature of a 44.5 gram sample of a metal from 33.9°c to 288.3°c. what is the heat capacity of the metal?

Explanation:

The formula for the amount heat q absorbed by a substance is

q = mcΔT

where

 m = the mass of the substance

  C = the specific heat capacity of the material

ΔT = the temperature change

Data:

 q = 2267 J

m = 44.5 g

T₁ = 33.9 °C

T₂ = 288.3 °C

Calculations:

ΔT = (288.3 - 33.9) °C = 254.4 °C

Sodium and chloride form an ionic bond. Therefore the sodium atom loses one electron from its outer shell and the chlorine atom gains one electron. As this happens, the electron is transferred from the sodium atom to the chloride atom and so both atoms become ionic and have a full outer shell.
