1.0.0- Introduction
1.0.1- Focus Question- If the mass of magnesium reacted with hydrochloric acid is changed will the temperature of the solution increase and the total mass decrease.
1.0.2- Hypothesis- If the mass of magnesium that is reacted with hydrochloric acid is changed the temperature of the solution will increase and the total mass will decrease.
1.0.3- Theory- The reaction between magnesium and hydrochloric reaction is written as follows, Mg(s)+ 2HCL (aq)—— (MgCl2(aq)+H2 (g) (Ng, 2008, pg 1). This reaction goes through two distinct changes that both have an effect on the energy change in the reaction. Enthalpy refers to changes in energy in a compound (Assut, 2008, pg 1). Two distinct changes can occur. An endothermic change occurs when the energy being absorbed is grater then the energy being released whereas and exothermic change is when the energy being released is greater than the energy being absorbed. Energy is absorbed when bonds are broken and energy is released when they are formed (Newton, 2008, pg1). Energy change cannot be directly measured.
