Enthalpy, Energy, Heat Worksheet. 1. Two beakers of water, one containing 50 mL and the other containing 250 mL, are heated to 75°C. Using these beakers as your examples, explain the difference between heat and temperature. 2. A quantity of gas was cooled from 323 K to 273 K. Express this temperature difference in degrees Celsius and Kelvins.
The specific heat capacity of zinc is 0.389 J K-1 g-1, and that of water near 100°C is 4.22 J K -1 g -1 . Calculate the final temperature reached by the zinc and the water.
Calculate the reaction enthalpy for the formation of anhydrous aluminum chloride by first stating the formation reaction and then using the data below: 2Al(s) + 6HCl(aq) à 2AlCl3(aq) + 3H2(g); ΔH = -‐149 kJ/mol HCl(g) à HCl(l); ΔH = -‐74 kJ/mol H2(g) + Cl2(g) à 2HCl(g); ΔH = -‐185 kJ/mol A...
