Nhi Vu General Chemistry Agnes Rafoulko Heat of Reaction Introduction : In this experiment, we will be determining the heat of reaction per mole of water formed, and then the heat of reaction per mole of magnesium reacted. Using the data obtained, we should be able to calculate the heat of reaction of magnesium metal with water by using Hess’s Law. Chemical Responsibility : The chemicals we are interacting with are toxic, corrosive, and/or easily absorbed through the skin. Thus, it is crucial that we wear safety goggles and safety gloves to prevent contact with skin and eyes. Should there be any contact, we must wash the contaminated area immediately with cold water. Also, Magnesium metal is a flammable solid. Report Sheet: Materials : • 2M HCl; 2M NaOH; plastic foam cup; magnesium metal Procedures : 1. Mix 75 mL of 2.0 M HCl with 75 mL of 2.0 M NaOH after measuring their respecting temperatures. After mixing, measure and record highest temperature. 2.
