A solution of 2.85 g of anhydrous aluminum chloride (AlCl3) in 56.02 g of water freezes at −2.84°C. Calculate the molar mass of AlCl3 from the formula. Calculate the molar mass from the freezing point depression, assuming AlCl3 does not dissociate in ions.

3.09 lab: reaction of metals 1 which combinations of substances resulted in a chemical change? for each metal that participated in a chemical change, write the type of metal it is, based on your examination of the periodic table. were there any metallic compounds that did not react with either the acid or the base? write the type of metal, based on your examination of the periodic table. make a general statement about the reactivity of the metals in this experiment.
