Help with this pure substances question please
If you cant see it ,
It says:
A beaker of distilled water was thought to have been contaminated with an impurity.The boiling point of the water was 108C. The contaminant was seperated and found to consist of white crystals. The melting point of the crystals was 190-210C.
a) explain whether the distilled water was contaminated.
B) suggest how the contaminant might have been seperated from the water.
C) Explain whether the contaminant was pure.
Please help tell me what the answers are because I don't know

Do you know what "contaminated" means?
Can you answer my question
What exactly is your question?
You have reproduced a published question without indicating what your desired outcome is.

a b and c (sic) are letters.
You have not specified exactly what it is that you do not understand.
Do you understand the concept of pure substance and mixture?
I just don't understand the questions I understand the concept

a) Yes the water sample is contaminated (as water has a boiling point of 100 degrees Celsius).
b) You can separate the contaminant from the water by vaporizing the water.
c) No, because the meltping point of the crystal contaminants vary, the contaminant isn't pure.
