The visual criterion which has to be assessed is to ensure it's not oily or sticky.
<h3>What is Distillation?</h3>
This is a separation technique that involves the use selective boiling and condensation to separate a liquid mixture into different components.
In the case of Crude reaction product , it is best to ensure that it is not oily or sticky before semimicro distillation is done.

Answer:
Chemoreceptors should be your answer :)
Explanation:
Answer:

Explanation:
In this case, to calculate the <u>heat of solution</u> (KJ/mol) we have to take into account the mass of water, the specific heat of the water and the temperature change, so:


Δ
With this in mind, we can use the <u>equation</u>:

If we plug the values into the equation we will have:


Now, with the mass value (21.5 g) and the molar mass of LiCl (42.39g/mol) we can <u>calculate the moles of LiCl</u>:

Now, in the heat of solution, we have <u>KJ/mol units</u>. Therefore, we have to <u>convert</u> from J to KJ:

Finally, we can <u>divide</u> by the moles of LiCl:

So, <u>for each mole of LiCl, we have 63.09 KJ involved in the dissolution process.</u>
I hope it helps!
