i say this because the others you will have time to prepare and you still might mess up.

but the one you will most likely mess up is during a class at school

for you wont have time to prepare and everyone tends to mess up the most when it comes to school speeches. plus it will still be hard even when you pay attention to the subject. unless you can easily have a conversation about the subject . or you will stuggle

No

Explanation:

We first find the solubility of the copper sulphate salt

Number of moles= 4.6 moles

Volume =1.75 L

Molarity= number of moles/ volume = 4.6/1.75= 2.6 molL-1

Hence, only 2.6 moles of Copper II sulphate dissolves in 1.75L of water. Hence 4.6 moles of copper II Sulphate dies not dissolve in 1.75 L of water.
