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.

A 147 gram piece of metal has a density of 7.00 g/mL. A 50 mL graduated cylinder contains 20.0vmL of water. What is the final volume after the metal is added to the graduated cylinder?
The amount of carbon-14 in ancient artifacts and fossils is often used to establish their age. Determine the number of protons and neutrons in a carbon-14 isotope and write its symbol in the form
Given a stock solution of a food dye having a concentration of 1.0 x 10-5 and an absorbance of 0.700. If a new solution is made by diluting exactly 10.0 mL of the solution with exactly 20.5 mL of distilled water, what should the absorbance of the ..
Calculate the systematic treatment of equilibrium. Remember C2O4^2- is a weak base so you must consider other equilibria. (Ksp(ZnC2O4)=7.5X10^-9, Kb1=1.8X10^-10, Kb2=1.8X10^-13). Solve using systematic treatment of equilibrium.
