What is the homogeneous material with with a variable composition?
No. A pure substances has a definite and constant composition.
What is the definition of a definite chemical composition?
Definite chemical composition is when a mineral is made of the same material throughout. Basically when a mineral is only made of one material all the way through, not part iron in one part and then gold in the rest.

What is the effect of column temperature on resolution?
Different substances have different boiling points. Distillation is the chemical process created to take advantage of this property. Cooling one side, the top of the column and applying a heat source to the bottom ensures lighter or more volatile substances accumulated at the top end of the column, assuming there is a constant flow with relative constant composition feeding the Distillation column, and an accumulation of less volatile material in the bottom.
State the law of definite proportions?
The law of definite proportions states that all chemical compounds have constant proportions of their components.
What are facts about pure substances?
cannot be separated into 2 or more substances by physical or mechanical meansis homogeneous, ie, has uniform composition throughout the whole sampleits properties are constant throughout the whole sampleits properties do not depend on how it is prepared or purifiedhas constant chemical composition

What is the similarties between mixture and substance?

What is the definition of pure substances?
A pure substance is a substance that consists solely of the same atoms/molecules.So a volume of water that contains only H2O is a pure substance. A block of iron that contains only Fe atoms is pure substance. A pure substance can be composed of atoms or molecules as I said before BUT they have to be exactly the same.A substance that has constant chemical composition and characteristics
