1. Heat can initiate reaction as well as be a product of chemical reactions. Cite the specific sample from the experiment that show heat acting in the manner.
2. Aluminum chloride was a product in step 6. How could you instruct your lab partner to recover it

1. In order to identify a specific sample from an experiment that shows heat acting as a reaction initiator or a product, it would be helpful to provide more details about the experiment you conducted. However, I can provide a general example of a chemical reaction where heat is involved.
One common example is the combustion of paper. When paper is burned, the reaction is exothermic, which means heat is released. This release of heat is evident through the observation of flames and the production of smoke and ash. Additionally, you can measure the temperature of the surroundings, which will increase due to the heat released during the combustion process.
It is important to note that there are numerous chemical reactions where heat can function as a reaction initiator or be produced as a product. By providing more context about your specific experiment, I can provide a more tailored example.
2. To recover aluminum chloride as a product from the reaction described, you can guide your lab partner through the following steps:
a. In a fume hood or a well-ventilated area, carefully pour the reaction mixture into a beaker or a container.
b. Add an excess of distilled water to the mixture and stir it well. This will help dissolve the water-soluble components and leave behind the aluminum chloride as a solid precipitate.
c. Attach a vacuum filtration setup (using a Buchner funnel, filter paper, and a vacuum pump) to a vacuum source.
d. Transfer the mixture into the Buchner funnel and turn on the vacuum pump to start the filtration process. The solid aluminum chloride will be retained on the filter paper while the liquid, containing the water-soluble components, will pass through.
e. Once the filtration is complete, carefully remove the filter paper with the aluminum chloride precipitate and place it in a watch glass or on a clean, dry surface.
f. Allow the precipitate to air dry or use a gentle stream of air to speed up the drying process.
g. Finally, collect the dry aluminum chloride and store it in a suitable container for further use or analysis.
It's worth mentioning that depending on the specific experiment and the impurities present, additional purification steps might be necessary to obtain highly pure aluminum chloride.
