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

You have not specified exactly what it is that you do not understand.
Do you understand the concept of pure substance and mixture?

b) You can separate the contaminant from the water by vaporizing the water.
