I've been stuck on this Determine the specific heat of ice using q = mC∆T where m = mass of water in calorimeter, C = specific heat of water, ∆T = change in temperature of water.

Determine the heat of fusion of ice using q = m∆Hf where q = heat, m = mass of substance being melted, ∆Hf = heat of fusion of substance being melted.

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.
