Q

What is fractional distillation?

A

A way of separating liquids that dissolve into each other (Miscible liquids)

22
Q

How does distillation work?

A

It heats the solution, the solvent evaporates and is trapped and condensed leaving only the solute.

23
Q

What is a compound?

A

Have a fixed ratio composition, chemical reactions must be used to separate them, there is bonds between the different elements.

24
Q

What is a mixture?

A

No fixed ratio, can separate easily (physically), no chemical bonds.

25
Q

What is the difference between a molecule and an atom?

A

A molecule is 2 or more atoms but an atom is singular element

26
Q

What is an atom with a positive charge called?

A

cations

27
Q

What is an atom with a negative charge called?

A

Anions

28
Q

What is a Solution?

A

the product of mixing a solute and solvent

29
Q

What is a solute?

A

something that dissolves in a liquid

30
Q

What is a solvent?

A

something that dissolves a solute

31
Q

What is the law of conservation of mass

A

The total mass of products formed in a reaction is equal to the mass of the reactants.
