What steps are necessary to determine the amounts of heat required to convert 100.0 g of solid Ca at 651oC into liquid Ca at 951oC. Then use the following information on Ca to calculate the amounts of heat for each of the heating steps.
Melting Point = 851 oC
Boiling Point = 1487 o C
Molar Heat Capacities
Csolid = 26.2 J/mol oC
Cliquid = 31.0 J/mol oC
ΔHfusion = 9.33 kJ/mol
ΔHvaporization = 162 kJ/mol
Part 1: Calculate the amounts of heat in kJ required to head the solid to its melting point.
Part 2: Calculate the amounts of heat in kJ required to melt the solid.
Part 3: Calculate the amounts of heat in kJ required, after the substance is melted, to heat the liquid to indicated temp.
