LAB 02. Separating a Mixture of Compounds lab-procedures-notes-Help Procedures Part 1: Separate the Ammonium Chloride 1. Take an evaporating dish from the Containers shelf and place it onto the workbench. 2. Take a balance from the Instruments shelf and place it on the workbench. 3. Move the evaporating dish onto the balance and record the mass of the empty evaporating dish to reference later. Mass of evaporating dish(g) 4. In this experiment, you will be using Mixture A (unless otherwise instructed). If your instructor has not specified which mixture to use, proceed with Mixture A. Take the assigned powder mixture from the Materials shelf and add 10 mL( 23.741g ) to the evaporating dish. Record the total mass of the evaporating dish plus the powder mixture. Mass of evaporating dish(g) and powdered mixture 5. Note: In a classroom laboratory, you would remove the container from the balance before you add any chemicals or solutions. Filling the container separately prevents any spills, sprays, or splashes that might affect your measurements when they land on the balance. Luckily virtual labs are spill-, spray-, and splash-free, so you can skip that step to save time. 6. Move the evaporating dish onto the workbench. 7. Take a thermometer from the Instruments shelf and place it onto the evaporating dish. The thermometer will display the room temperature of 21.5 °C. Record this temperature. 8. Take a Bunsen burner from the Instruments shelf and place it onto the workbench. 9. Move the evaporating dish onto the Bunsen burner.
