You are going to investigate the temperature change when magnesium reacts with dilute sulfuric acid. Read all of the instructions carefully before starting the experiments. Instructions You are going to do five experiments. Experiment 1 - Use a $$\(25 \mathrm{~cm}^{3}\)$$ measuring cylinder to pour $$\(20 \mathrm{~cm}^{3}\)$$ of dilute sulfuric acid into a boiling tube. - Use a thermometer to measure the initial temperature of the acid in the boiling tube. Record the initial temperature in Table 1.1. - Add a coiled 5 cm length of magnesium ribbon to the acid in the boiling tube. At the same time start a timer. - Continually stir the contents of the boiling tube using the thermometer. - After 45 seconds, measure the temperature of the mixture in the boiling tube. Record this temperature in Table 1.1. - Rinse the boiling tube with distilled water. Experiment 2 - Use the $$\(25 \mathrm{~cm}^{3}\)$$ measuring cylinder to pour $$\(20 \mathrm{~cm}^{3}\)$$ of dilute sulfuric acid into the boiling tube. - Use a $$\(10 \mathrm{~cm}^{3}\)$$ measuring cylinder to add $$\(2.0 \mathrm{~cm}^{3}\)$$ of distilled water to the acid in the boiling tube. - Place a bung in the boiling tube and invert the tube to mix the acid and water. - Use the thermometer to measure the initial temperature of the contents of the boiling tube. Record the initial temperature in Table 1.1. - Add a coiled 5 cm length of magnesium ribbon to the contents of the boiling tube. At the same time start the timer. - Continually stir the contents of the boiling tube using the thermometer. - After 45 seconds, measure the temperature of the mixture. Record this temperature in Table 1.1. - Rinse the boiling tube with distilled water. Experiment 3 - Repeat Experiment 2, adding $$\(4.0 \mathrm{~cm}^{3}\)$$ of distilled water instead of $$\(2.0 \mathrm{~cm}^{3}\)$$. Experiment 4 - Repeat Experiment 2, adding $$\(6.0 \mathrm{~cm}^{3}\)$$ of distilled water instead of $$\(2.0 \mathrm{~cm}^{3}\)$$. Experiment 5 - Repeat Experiment 2, adding $$\(10.0 \mathrm{~cm}^{3}\)$$ of distilled water instead of $$\(2.0 \mathrm{~cm}^{3}\)$$. Complete Table 1.1. Table 1.1
