When calcium nitrate, Ca(NO3)2, dissolves in water, it dissociates into its ions. We can represent that process by the following equation: Ca(NO3)2(s) → Ca2+(aq) + 2NO3-(aq) When 1.5 mol calcium nitrate dissolves in water, how many moles of ions should be present in solution? Group of answer choices

Magnesium is the limiting reactant in this experiment. calculate the theoretical yield of mgo for each trial. trial 1: trial 2: data mass of empty crucible with lid trial 1: 26.688 trial 2: 26.681 mass of mg metal, crucible, and lid trial 1: 26.994 trial: 2 26.985 mass of mgo, crucible, and lid trial 1: 27.188 trial 2: 27.180
