Cockermouth School - GCSE Chemical change (metals)

What is the reactivity series?

• Periodic table
• Sports event
• General reactivity of atoms
• Order of element reactivity

How can metals be placed in order of their reactivity?

• Comparing flammability
• Comparing reactions of metals with acid
• Comparing general properties
• Comparing colour

What is the name for a reaction where oxygen is removed from a compound?

• Oxidation
• Reduction
• Deoxidation
• Oxidation

Explain why zinc can be extracted from zinc oxide with carbon

• Carbon is more reactive than zinc
• Carbon is less reactive
• Carbon is more attractive
• Carbon is less attractive

Explain why gold and silver can be found naturally in the Earth's crust

• They are very unreactive
• Lucky
• They're expensive
• They are used for jewellery

What process is used to extract metals more reactive than carbon

• Smelting
• Electrolysis
• Burning
• Neutralisation

What is a material containing enough metal in it for it to be economically worthwhile to extract the metal.

• Compound
• Oar
• Ore
• Phytomining

What type of reaction occurs when a more reactive element takes the place of a less reactive element?

• Phytomining
• Neutralisation
• Hydrolysis
• Displacement

Define oxidation in terms of electrons

• Loss of electrons
• Gain of electrons
• Electrons are maintained
• Electrons anihilate

Define reduction in the context of loss and gain of electrons

• Loss of electons
• Reduction is the gain of electrons
• Electrons are maintained
• Electrons anihilate
