Lab 14 Heat of Reaction Objective: To experimentally determine the heat of reaction for two exothermic reactions. Consider the following equations. (1) Mg(s) + 2HCI → MgCl2(aq) + H2(g) Hz(8) AH = ? (2) MgO(s) + 2HCl(aq) → MgCl(aq) + HOH (1) AH2 = ? The reactions represented by equations (1) and (2) will be our experimental work for today. Background: The heat given off or gained in a reaction is commonly called the heat of reaction. A reaction that...

Titration of Hydrochloric Acid: 1) Use the buret that is located near the hydrochloric acid container to dispense 25.00 mL of hydrochloric acid solution into a clean dry 100 mL beaker. Record the molarity of this solution on your data sheet. 2) Check to make sure that the volume on your sodium hydroxide buret reads 0.00 mL. If it does not read 0.00 mL, adjust it...

4. Construct a flow chart describing the separation of the mixture and the isolation of each compound in this experiment. A commonly used method of separating a mixture of organic compounds is known as liquid-liquid extraction. Most reactions of organic compounds require extraction at some stage of product purification. In this experiment you will use extraction...
