1

How did mandeleev overcome the problem of undiscovered elements?

1

How were the early periodic tables arranged?

1

How is the modern periodic table ordered?

1

Elements in the same group have the same number of...

4

Characteristics of group 1:

1

The further up the group 1 the more reactive and lower its melting poit

1

Characteristics of transition elements compared with group1:

1

Transition metals are useful catalysts

1

What are group 7 elements known as?

1

The further down group 7 the less reactive and the higher melting point.

1

A more reactive halogen can displace a less reactive halogen from an..

1

The more energy levels an element has the less reactive it is

1

Hard water can contain..

1

Which type of water form a lather readily?

1

There are two types of hard water temporary hard water and permanent hard water

1

Scum is formed by the decomposition of Hydrogencarbonate ions in temporary hard water

1

What are two ways that hardness can be removed?

1

What are two things that water should have low levels of?

1

Pure water can be produced by distillation

1

What do water filters contain to remove some dissolved substances from water?

1

Chlorine is added to water to increase microbes and flourine isn't added to improve dental health

1

How is energy released from substances measured?

1

Why in a chemical reaction should the reagents be mixed in an insulated container?

1

During a reaction energy is needed to make bonds and energy is released when breaking bonds

3

Three things to do when drawing an energy diagram:

1

In an exothermic reaction more energy is released to make bonds than break them

1

Catalysts higher the activation energy

4

Tick the 4 true facts:

1

Aluminium, calcium and magnesium ions form white precipitates

1

What colour precipitate does copper form?

1

What colour precipitate does iron (lll) ions form?

1

What colour precipitate does iron(ll) ions give?

1

Carbonates react with dilute acid to form carbon dioxide

1

Halide ions can be tested by adding what and what then looking at the precipitates?

1

To test sulphate ions add hydrochloric acid and barium chloride solution

1

How can volumes of acid and alkali solutions that react with each other be measured?

2

What are the raw materials in the haber process?

1

What is the temperature and pressure in the haber process?

1

Ammonia is produced in the haber process

1

Equilibrium is reached when the reactions occur at the same rate in each direction

1

To increase the yield in a reaction that is exothermic in the forward direction what do you do?

1

What can you do to increase the yield when the forward reaction has more gaseous molecules?

1

We have to compromise temperature, pressure and rate of reaction in the haber process

1

Which functional group is for alcohols?

1

Which functional group is for esters?

1

What is the functional group for acids?

3

1

Oxidising ethanol makes ethanoic acid

4

4 characteristics of carboxylic acids:
