Download the observations from today’s demonstration and complete the Double Replacement reactions. We will use the solubility rules table to determine the physical states of the products for each reaction. Bring these reactions to tutorial this week! Question 1: The combustion of propane, CH3CH2CH3, produces carbon dioxide, water vapour and heat. Write the balanced chemical equation for this reaction and include the heat on the correct side of the reaction. Answer to Question 1: Combustion reaction always involves oxygen, O2 (g). Combustion reaction involving hydrocarbons (compounds made up of . . . → Read More: Lab: Experiment 7 Practice Questions Objectives To observe the techniques involved to remove water from a hydrated salt, copper (II) sulphate pentahydrate, CuSO4 · 5H2O, quantitatively.
