Inquiry Question 1: Properties of Matter

Question 1

Homogenous Mixtures

Answer 1

Uniform in composition throughout

Question 2

Heterogenous Mixtures

Answer 2

Non-uniform composition
Composition varies throughout mixture
Can see different

Question 3

Filtration

Answer 3

Separates solids from liquids / solutions using a filter funnel or filter paper
Relies on states of matter + size

Question 4

Sieving

Answer 4

Separates solids of different sizes with a sieve

Relies on particle size

Question 5

Distillation

Answer 5

Separates liquids using differences in boiling points with a condenser
Relies on a big difference in boiling points

Question 6

Evaporation

Answer 6

Separates a solid dissolved in a liquid by boiling off the liquid in an evaporation dish
Relies on liquid having a much lower boiling point than the solid

Question 7

Calculating percentage composition

Answer 7

(mass of substance/total mass of mixture) x 100

Question 8

Nomenclature terms: binary ionic compounds

Answer 8

Metal and non-metal 
Metal named first 
If metal has more than one charge  indicate with roman numeral or:
-	ous = lower charge 
-	ic = higher charge

Question 9

Nomenclature terms: binary covalent compounds

Answer 9

two non-metals
less electronegative element first
second element = ide ending
Greek prefixes = subscripts

Question 10

Nomenclature terms: 1

Answer 10

Mono

Question 11

Nomenclature terms: 2

Answer 11

Di

Question 12

Nomenclature terms: 3

Answer 12

Tri

Question 13

Nomenclature terms: 4

Answer 13

Tetra

Question 14

Nomenclature terms: 5

Answer 14

Penta

Question 15

Nomenclature terms: 6

Answer 15

Hexa

Question 16

Nomenclature terms: 7

Answer 16

Hepta

Question 17

Nomenclature terms: 8

Answer 17

Octa

Question 18

Nomenclature terms: nonbinary compound

Answer 18

More than two elements
Usually contains polyatomic ions
Name polyatomic cation then anion

Question 19

Chemical properties

Answer 19

A substance changes into a different substance
When a chemical reaction causes bonds to break + new ones to form
Evidence of a chemical reaction = change in colour, odour, formation of precipitate
E.g. burning, rusting, tarnishing

Question 20

Physical properties

Answer 20

A change in a substance that does not change what the substance is
Evidence of change = change in shape, size, form and phase
E.g. melting, boiling, evaporating, condensation and freezing
