3.00 g of the hydrate CoCl2.xH2O was heated and after the water was driven off, 1.64 g of CoCl2 remained. (Use these atomic masses: Co = 59 Cl= 35.5 H = 1 O =16 ) You are required to find x by following the steps outlined below.
Find the following:
a. The mass of water driven off
b. The number of moles of H2O driven off
c. The number of moles of CoCl2 formed
d. The number of moles of H2O divide by the number of moles of CoCl2 = x (write as a whole number)
e. The full formula of the hydrate

You just calculated that the heat of fusion for chloromethane is 6400 j/mol. the heat of fusion for hydrogen is 120 j/mol.? which of the following account for this difference? more than one correcta. chloromethane can absorb more energy at the same temperature. b. hydrogen has stronger intermolecular forces than chloromethane. c. hydrogen molecules can pack more closely than chloromethane molecules. d. chloromethane experiences dipole-dipole interactions. e. chloromethane has a higher molar mass than hydrogen.
