14 is C but I cannot see the other one
False should be your answer
Answer:

Explanation:
Answer: The formula for this hydrate is 
Explanation:
Decomposition of hydrated copper sulphate is given by:
Molar mass of 
= 160 g/mol
According to stoichiometry:
(160+18x) g of 
decomposes to give 160 g of anhydrous
Thus 42.75 g of decomposes to give=
g of anhydrous
Thus the formula for this hydrate is
Answer;
-Distillation
Explanation;
Distillation is a technique that can be used to physically separate most homogeneous mixtures based on the difference in the boiling points of the substances involved.
A good example; A flask hold liquids A, B, and C in a homogeneous mixture. The boiling points of A, B, and C are 130 C, 65 C, and 71 C, respectively. The flask is heated to 65C until all of liquid B is filtered out. The remaining mixture is heated to 71C until all of liquid C is filtered out, and only liquid A is left in the flask.
