zinc carbonate
lead(II) carbonate
copper(II) carbonate
iron(III) carbonate
Samples of zinc and aluminium of the same mass were reacted separately with iron(II) chloride of the same concentration. A reaction was observed for zinc and iron(II) sulfate but not for aluminium and iron(II) sulfate.
Which of the following is a reason for this observation?
Aluminium is unreactive.
Zinc has a greater tendency to lose electrons.
Aluminium forms a protective layer of oxide.
Aluminium forms a layer of rust around it.
Which of the following metal oxides can be reduced by carbon but not by hydrogen?
potassium
magnesium
zinc
copper
Why are metals higher up the reactivity series (eg. potassium, sodium) extracted by electrolysis and not by reduction with carbon?
Electricity is more readily available than carbon.
More reactive metals have a lower melting point.
More reactive metals usually have larger amounts of impurities.
More reactive metals form more stable oxides with stronger electrostatic forces of attraction.
