Question 1

What is chromatography

Answer 1

Separating solutions dissolved in the same solvent

Question 2

What is fractional distillation

Answer 2

Separate two different liquids based on different boiling points

Question 3

What is filtration

Answer 3

Separating soluble and insoluble substances

Question 4

Required practical-what is fractional distillation

Answer 4

The heat of substance in the fractional column
Lowest boiling point will evaporate first
Substances and other content and cool
When the first liquid is collected you raise the temp until the next one reaches the top

Question 5

What is crystallisation

Answer 5

Remove the liquid leaving a solid behind

Question 6

What does the number of protons equal

Answer 6

The number of electrons

Question 7

What a compound

Answer 7

When two or more elements react

Question 8

Required practical-what is crystallisation

Answer 8

I thought relation dish will heat 
up let it cool 
filter it 
leave to dry out 
crystals with then form

Question 9

What is the mass number

Answer 9

Protons + neutrons in the nucleus

Question 10

What is the atomic number

Answer 10

Number of protons

Question 11

What is an isotope

Answer 11

An element with same number of protons and different number of neutrons

Question 12

Required practical-What is filtration

Answer 12

Put filterpaper into the funnel
Pour mixture onto the filter paper
Make sure mixture doesn’t go above the paper
Liquid will pass through paper and into the beaker
The solid is left behind in the paper

Question 13

What is simple distillation

Answer 13

Separate the liquid from its solvent

Question 14

Require practical-what is simple distillation

Answer 14

Heat solution
Part with lowest boiling point evaporates first to turn Into a gas
Gas travel to condenser
The gas has cooled and turns into liquid
Liquid will drop out condenser to be collected

Rest of solution will be left in flask

Question 15

What do we use separate a mixture

Answer 15

Filtration crystallisation simple distillation or factual distillation

Question 16

What is a mixture

Answer 16

Contains at least two different elements or compounds

Question 17

What happens if an atom doesn’t have a full putter shell

Answer 17

They react to fill it

Question 18

What does it mean if they have a full shell

Answer 18

They are more stable

Question 19

What does the number of electrons in the outer shell shell

Answer 19

Which group their in

Question 20

Require practical-what is chromatography

Answer 20

Draw a line on the chromatography paper
Is five pencil spot equal spaces across the line
Add a spot of ink to each dot on the line
Pour a small amount of solvent in a beaker and place a sheet in the beaker but it mustn’t be touching the solvent
Put lid on top to stop it evaporation
So that means that the paper ticket with it it takes it out and need to try
