Question

you will need to construct a flowchart or write out a procedure for the experiment as explained in the lab syllabus. this must be handwritten. the specific instructions are given again below. after completing your flowchart/procedure, please answer the following questions and turn them in with your flowchart/procedure. 1. at what temperature does ammonium chloride sublime? 2. what does the term “decantation” mean? remember that this prelab assignment must be turned in as soon as you walk into the lab room. you will not be permitted to do the experiment if this assignment is not done.

Explanation:

1. Ammonium chloride sublimes at around 338 °C. This is a well - known property in chemistry where a solid directly changes to a gas without passing through the liquid state.
2. Decantation is a separation technique in chemistry. It involves carefully pouring off a liquid layer from a mixture, leaving a solid or a denser liquid behind.

Answer:

1. Around 338 °C
2. A separation technique where a liquid is carefully poured off from a mixture, leaving a solid or denser liquid behind.
