We use metals in our everyday lives, for example in jewellery or in cars. Different metals react differently with oxygen, water and dilute acid, allowing a reactivity series to be deduced.
Which of the following groups of three metals is arranged in order of increasing chemical reactivity?
Potassium, iron, lead
Gold, tin, sodium
Zinc, calcium, silver
Which of the following metals will react with water?
How was the reactivity series made?
By comparing metals in different chemical reactions
By testing the hardness of different metals
By the position of metals in the periodic table
Which process cannot be used to separate iron from iron ore?
Heating the ore with carbon monoxide
Heating the ore
Which of the following pairs of metals can only be extracted from their ores by electrolysis?
Copper and tin
Magnesium and iron
Potassium and aluminium
Which of these pairs of metals would produce the highest voltage in a cell?
Zinc and lead
Iron and nickel
Magnesium and silver
Which of the following is an example of chemical protection used to prevent iron objects rusting?
What colour does ferroxyl indicator change to indicating that iron is beginning to rust?
What name is given to a mixture of metals?
Which of the following is an alloy?
