When 2.26 g of liquid PCl3 at 12.4 C is added to a solution of water at in a coffee cup calorimeter, the temperature of the solution increases to 42.3C. If the heat
capacity of the solution and calorimeter is 421.7 J/C, calculate the molar heat of the
PCl3. Answer to 0 decimal places in kJ/mol.

Predict the reactants of this chemical reaction. that is, fill in the left side of the chemical equation. be sure the equation you submit is balanced. (you can edit both sides of the equation to balance it, if you need to.) note: you are writing the molecular, and not the net ionic equation. > cacl2(aq) + h20(l)
