Chemistry 1 states of matter and purifying substances

Question 1

What is a molecule

Answer 1

2 or more atoms that are chemically bonded

Question 2

What is a compound

Answer 2

2 or more different elements chemically bonded

Question 3

What is a mixture

Answer 3

Two or more substances which are not chemically combined

Question 4

What is filtration

Answer 4

Is used to separate insolvable solid from liquid

Question 5

What is the process

Answer 5

Pour mixture through filter paper into conical flask
Liquid goes through pores of paper
Solid remains

Question 6

What is crystallisation

Answer 6

Is used to separate a solvable solid from a liquid

Question 7

What is the process

Answer 7

Heat up the solution let it dissolve
Asfter a couple days the solvable solid will be left to form crystals

Question 8

What is distillation

Answer 8

Heat Evaporate liquid by vapour In a flask
The vapour will then run through into condenser
Combes sorry is cold as cool water around it
The liquid is then created
Leaving the crystals behind
Used to produce drinking water

Question 9

What is fractional distillation

Answer 9

Is used to separate a mixture of liquids

Question 10

What is process

Answer 10

The liquids must have different boiling points
The flask is atttched to fractional column contains glass beads
then the same asimple distillation
Start by heating mixture however will evaporate a diff boiling points and diff times
They then condense t
This reappears until they are all condensed
