,A substance with different elements or compounds not chemically
combined - 🧠 ANSWER ✔✔What is a mixture?
Sand and water as they are not chemically combined and can be separated
by physical means - 🧠 ANSWER ✔✔Give an example of a mixture
A substance that has any elements chemically joined - 🧠 ANSWER
✔✔What is a molecule?
the elements in a molecule and the number of atoms of each element - 🧠
ANSWER ✔✔What does a chemical formula tell you about a molecule?
Each element symbol starts with a capital letter, if there is a second letter it
is in lower case - 🧠 ANSWER ✔✔How is a chemical formula presented?
- 🧠 ANSWER ✔✔Give an example of a chemical formula
State symbols show the physical state of the substance solid (s), liquid (l),
gas (g), or dissolved in water (aq) - 🧠 ANSWER ✔✔What are state
symbols?
-Strong
-Good conductors of heat and electricity

,-High melting and boiling points - 🧠 ANSWER ✔✔Name three properties of
Metals
-Weak
-Bad conductors of heat and electricity
-Low melting and boiling points - 🧠 ANSWER ✔✔Name three properties of
Non-Metals
Filtration, crystallisation, distillation or chromatography - 🧠 ANSWER
✔✔State the four different ways of separating mixtures
Pour your mixture onto the filter paper through the filter funnel, the liquid
simply passes through the filter paper into the flask. The insoluble solid
cannot pass through so the residue remains on the paper - 🧠 ANSWER
✔✔Describe the process of filtration
Use the method of filtration to filter off any excess soluble solid. Transfer
the mixture into an evaporating basin and gently heat until crystals start to
form. Leave the solution to cool and crystals should form. - 🧠 ANSWER
✔✔Describe the process of crystallisation
Poor the solution in the distillation flask and attach a water condenser to it.
Put a beaker at the outlet of the condenser. evaporate the mixture by

, heating it (the solution with the lowest boiling point will evaporate first. The
vapours condense in the condenser. The rest of the solution is left in the
flask - 🧠 ANSWER ✔✔Describe the process of simple distillation
Take a strip of filter paper and draw a line on the bottom of the paper. Put a
small drop of ink on the line, take a beaker full of water up to the line and
put the filter paper in. As the water moves up we see different colours on
the paper these are the dyes in the ink - 🧠 ANSWER ✔✔Describe the
process of chromatography
Simple distillation - 🧠 ANSWER ✔✔How can you get pure water from sea
water?
It can only be used to separate things with very different boiling points - 🧠
ANSWER ✔✔What are the problems with simple distillation?
Put mixture in flask and add fractional Column to the top, then heat. The
different liquids have different building points so they will evaporate at
different temperatures. The liquid with the lowest boiling point evaporated
first. - 🧠 ANSWER ✔✔Fractional distillation
