Reactivity Series and Displacement Reactions
Karten in diesem Stapel (15)
- 1List the Reactivity Series in order.Potassium, Sodium, Calcium, Magnesium, Aluminium, Zinc, Iron, Lead, Copper, Silver, Gold
- 2More reactive metals are harder to extract from their ores. What do they need?Electrolysis- when chemical energy breaks down the ores
- 3Why does aluminium seem so unreactive when it's high up in the reactivity seriesWhen aluminium reacts with oxygen, it makes a protective oxide layer which stops further reactions.
- 4What will happen to most metals when they react with air?They tarnish; makes a dull layer of metal oxide on surface.
- 5What happens when magnesium, lead and silver is burnt in air?Magnesium- burns violently
Lead- reacts slowly
Silver- no reaction - 6Metal+Oxygen=Metal Oxide
- 7More reactive metals react vigourously with ........ water to produce ........cold, hydroxides
- 8Less reactive metals react quickly with ...... to produce.......steam, oxides
- 9Metal + Water = Less Reactive Metal+ Steams=Metal Hydroxide + Hydrogen
Metal Oxide + Hydrogen - 10The lower the ........, the ..... visible the reaction of metals with acid.reactivity, less
- 11Metal + Acid=Salt + Hydrogen
- 12What is the test for hydrogen?When a lit splint is near hydrogen, there will be a squeaky pop.
- 13What does Displacment mean?Taking place of
- 14What is the rule for displacement reactions?A more reactive metal will displace a less reactive metal.
- 15Magnesium + Copper Sulphate= Copper + Zinc Sulphate=Magnesium Sulphate + Copper
