question 7 (1 point)
at the end of the experiment, your sample will need to dry. during this time, you need
to clean up your workspace for the next lab. you will have a vacuum setup filled with
liquid waste and the leftover aluminum wire solid waste. select the appropriate and
safest waste disposal procedure.
discard the aluminum in the appropriate solid waste container, which is separate
from the liquid waste.
pour the liquid down the drain and throw the aluminum wire into a trash can.
discard the aluminum in the appropriate solid waste container and leave the
vacuum setup filled.
dump the solid waste and the liquid waste together.

Explanation:

In a laboratory setting, proper waste disposal is crucial for safety and compliance. Liquid waste and solid waste (like aluminum wire) should be separated. Pouring liquid waste down the drain (without proper treatment if needed) can be hazardous to plumbing and the environment. Dumping solid and liquid waste together is incorrect as they have different disposal protocols. Leaving a vacuum setup filled is not relevant to waste disposal. The correct procedure is to put the aluminum (solid waste) in the appropriate solid waste container and separately handle the liquid waste (though the option for liquid waste disposal here isn't fully correct as it might need more specific handling like a waste - liquid container, but among the options, separating solid and liquid is key).

Answer:

Discard the aluminum in the appropriate solid waste container, which is separate from the liquid waste.
