Back (Answer)

Metal oxide

Front (Question)

Metal + Water → …

Back (Answer)

Metal hydroxide + Hydrogen

Front (Question)

Metal + Acid → …

Back (Answer)

Salt + Hydrogen

Front (Question)

Chemical test for hydrogen gas

Back (Answer)

Burns with a (squeaky) pop

Front (Question)

Very reactive metals must be extracted from their ores via …

Back (Answer)

electrolysis.

Front (Question)

Metals around the middle of the ECS can be extracted from their ores via …

Back (Answer)

heating with carbon.

Front (Question)

Very unreactive metals can be extracted from their ores via …

Back (Answer)

heating alone.

Front (Question)

What type of metal pairs generate higher voltages in electrochemical cells?

Back (Answer)

Far apart in the ECS

Front (Question)

What is the direction of electron flow in electrochemical cells?

Back (Answer)

From metal higher in the ECS to metal lower in the ECS (remember - electrons flow down)

#10

Front (Question)

Describe the structure of a metal lattice

Back (Answer)

Positive metal ions surrounded by delocalised electrons

#11

Front (Question)

Metallic bond

Back (Answer)

Electrostatic attraction between positive metal ions and delocalised electrons

#12

Front (Question)

Displacement reaction

Back (Answer)

A reaction in which a more reactive metal displaces a less reactive metal from a compound. E.g. Mg + FeSO4 → MgSO4 + Fe

#13

Front (Question)

What allows metals to conduct electricity?

Back (Answer)

Delocalised electrons (charged particles + free to move)

#14

Front (Question)

Why must a d.c. supply be used during electrolysis?

Back (Answer)

So that the products can be identified.

#15

Front (Question)

Redox reaction

Back (Answer)

A reaction involving a transfer of electrons. (One reactant loses electrons, the other gains them)

#16

Front (Question)

Loss of electrons

Back (Answer)

Oxidation (remember - OIL RIG)

#17

Front (Question)

Gain of electrons

Back (Answer)

Reduction (remember - OIL RIG)

#18

Front (Question)

Oxidation

Back (Answer)

Loss of electrons (rememeber - OIL RIG)

#19

Front (Question)

Reduction

Back (Answer)

Gain of electrons (rememeber - OIL RIG)

#20

Front (Question)

How do you turn this reduction equation into an oxidation equation? Cu2+ + 2e– → Cu

Back (Answer)

Reverse it Cu → Cu2+ + 2e–

#21

Front (Question)

When copying equations from the ECS, which equation gets reversed?

Back (Answer)

The one higher up in the ECS

#22

Front (Question)

What has to be done before these equations can be added up?

Back (Answer)

Electrons must be balanced (so multiply whole Na equation by 2)

#23

Front (Question)

What type of reaction is this? MgO + H2SO4 → MgSO4 + H2O

Back (Answer)

Neutralisation (base + acid)

#24

Front (Question)

What type of reaction is this? C2H4 + Br2 → C2H4Br2

Back (Answer)

Addition (multiple reactants, only one product)
