And here are the potential answers...
So what's this question asking?
Looks like a critical thinking problem.
We have to figure out why the experiment went wrong based on what we know.
First things first, what's the proper procedure for the experiment?
Let's just follow the steps that they gave us:
Step 1- filter paper. Step 2- distillation chamber.
What was supposed to happen during each step?
Step 1- remove sand. Step 2- isolate salt.
So what went wrong in this question?
This student ended up with salt and sand in the distillation chamber.
But...step 2 says we should only have salt left in the distillation chamber.
Somehow, this student forgot to get rid of the sand before using the chamber.
Hmm, how could that have happened?
Could it be...that the careless student forgot to do step 1?
Forgetting the first step in this experiment means that the sand never got removed from
the salt and water, and was left with the salt in the distillation chamber.
Sounds like exactly what happened to this poor befuddled student.
Option C's the correct answer.
