Welcome back MASTER — been a while! Let's pick up where you left off. Here are the solutions for the questions: c) To prepare and collect dry samples of chlorine and ammonia gas: • For chlorine gas (Cl_2(g)): Chlorine is denser than air, so it is collected by downward delivery (upward displacement of air). • For ammonia gas (NH_3(g)): Ammonia is less dense than air, so it is collected by upward delivery (downward displacement of air). d) (i) Name the apparatus: The apparatus shown is a thermometer. d) (ii) Complete the table below: Step 1: Read the temperature before addition from the first thermometer. The thermometer shows the mercury level at the 8th mark after 26, which is 26.8 °C. Step 2: Read the temperature after addition from the second thermometer. The thermometer shows the mercury level at the 2nd mark after 33, which is 33.2 °C. Step 3: Calculate the temperature change. Temperature change = Temperature after addition - Temperature before addition Temperature change = 33.2 °C - 26.8 °C Temperature change = 6.4 °C The completed table is: | | | | :-------------------------- | :-------------------- | | Temperature after addition | 33.2 °C | | Temperature before addition | 26.8 °C | | Temperature change | 6.4 °C | Send me the next one 📸
