Hi, I am providing all of the information as it is probably needed to answer the last couple of questions. I need help answering the last three boxes.
1. Calculate the heat released into the solution for the 3 reactions, according to Reaction= Ccal*Delta T+ m contents * Cp contents * Delta T.
2. Find the molar heat of reaction for each experiment in units of Kilo-Joules / (mole of Mg) by dividing the heat of reaction by the moles of Mg used.
3. Calculate and record the average molar heat of reaction from the three results.
Thank you for your help.
