1. The problem statement, all variables and given/known data The reaction between 0.045 g of calcium with an excess of water was carried out in an ice calorimeter as used in this lab. The volume of water in the calorimeter decreased by 0.18 mL during the reaction a) Write the equation for the reaction which occurs. Is it a redox reaction? b) Calculate the enthalpy of the reaction (in kJ/mol). Show all steps of calculation. 2. Relevant equations it was given on the previous page that m = delta Volume * (-11.05) 3. The attempt at a solution I got part a, but im having a lot of trouble with part b. im not even sure where to start. m = (-.18)(-11.05) = 2.0 Where do we go form here, to find the enthalpy?
