Reactions With Metals

Question 0

Part of metal affected in reaction with air

Answer 0

Only outside layer

Question 1

Metal and air product

Answer 1

Metal oxide

Question 2

Metals and water produces

Answer 2

Alkali and hydrogen gas

Question 3

How does the reaction change the higher up the reactivity series the metal for reactions with water

Answer 3

The larger the reactions - magnesium needed to be in water vapour for the reaction to take place

Question 4

What metals react with acid

Answer 4

Only metals above hydrogen as hydrogen is in all acids and is being displaced in the reaction

Question 5

Why does a metal react with an acid

Answer 5

It displaces hydrogen

Question 6

The further up the reactivity series what changes with acid and metal reactions

Answer 6

The more strong more effervescence

Question 7

Metal + acid ->

Answer 7

Salt + hydrogen (gas)

Question 8

_ + _ -> salt + hydrogen

Answer 8

Metal + acid

Question 9

Salt

Answer 9

Name of metal + part of acid name

Question 10

Mg + 2HCl ->

Answer 10

MgCl2 + H2

Question 11

How does reaction change when the metal is in powder form?? Why

Answer 11

Stronger reaction - larger surface area

Question 12

Nitric acid salt name

Answer 12

Nitrate

Question 13

Sulphuric acid salt name

Answer 13

Sulphate

Question 14

Hydrochloride acid salt name

Answer 14

Chloride

Question 15

Metal carbonates + acid ->

Answer 15

Salt + carbon dioxide + water

Question 16

Displacement reactions of oxides - give example using zinc and copper oxide

Answer 16

Zn + CuO -> ZnP + Cu

Question 17

Displacement reactions why does the metal oxide get displaced

Answer 17

Less reactive than one doing the displacing ‘reducing agent’

Question 18

Reducing agent?

Answer 18

One doing the displacing in a displacement or reduction reaction
