0 1 A A student added magnesium, zinc, and copper to solutions of magnesium sulfate, zinc
sulfate, and copper sulfate. The table below shows some of the results:
Metal Magnesium sulfate Zinc sulfate Copper
sulfate
Magnesium X ✔
Zinc X
Copper X X
Key:
✔ Reaction occurs
X No reaction
1. Complete the table above by filling in the missing reactions using the reactivity series.
[2 Marks]
1. Write a word equation for the reaction between zinc and copper sulfate.
0 1 B _Zinc + Copper sulfate → _______ + _______
[1 Marks]
2. Why does no reaction occur when copper is added to magnesium sulfate? Tick one box:
o Copper is more reactive than magnesium.
o Magnesium is more reactive than copper.
o Both metals have the same reactivity.
A teacher demonstrated the reaction of potassium with water. The reaction was
vigorous, producing hydrogen gas and forming an alkaline solution. [1 Marks]
