Question paper
1 A student carries out an investigation to compare the reactivities of four
metals, aluminium, copper, zinc and M.
He adds strips of zinc to the aqueous solutions of the nitrates of each metal.
After a few minutes he removes the strips of zinc and examines them.
The table shows his results.
Solution Result
aluminium nitrate no change
copper(II) nitrate brown coating on zinc
zinc nitrate no change
nitrate of metal M grey coating on zinc
(a) Name the substance that causes the brown coating on the
zinc.
............................................................................................................................... ............................................................................................................................... ......................
(b) State why there is no change in the experiment with zinc nitrate solution.

(c) The student repeats the experiment with strips of metal M instead of strips of zinc.
The table shows his results.
Solution Result
aluminium nitrate no change
copper(II) nitrate brown coating on M
zinc nitrate no change
nitrate of metal M no change
Using information from both tables of results, place the metals aluminium, copper,
zinc and M in order of decreasing reactivity.

(d) The table gives information about the first five elements in Group 2 of the Periodic Table.
Atomic Reaction with cold
Element Reaction with air
number water
beryllium 4 no reaction burns when strongly heated
magnesium 12 reacts very slowly burns when heated
calcium 20 reacts slowly reacts slowly without heating
strontium 38 reacts quickly reacts quickly without heating
barium 56
Use the information in the table to help you answer the questions.
(i) Suggest how barium reacts with cold water and with air.

2. Some chemical properties of three metals W, X and Y and their oxides are shown.
What is the order of reactivity of these metals, most reactive first?
A W→Y→X
B X→Y→W
C Y→W→X
DY→X→W
3. The list shows the order of reactivity of some elements.
K N Ca Mg Zn Fe (H)
Which statement about the reactivity of these metals is correct?
A Copper reacts with steam to form hydrogen gas.
B Magnesium is more reactive than calcium.
C Potassium reacts with water to form hydrogen gas.
D Sodium oxide is reduced by carbon to sodium.
4.Which substances do not react together?
a. calcium + water
b. copper + dilute hydrochloric acid
c. sodium + water
d. zinc + dilute hydrochloric acid
5. The diagrams show what happens when three different metals are added to water.
bubbles of gas
flame
X Y Z
What are X, Y and Z?
6. In an experiment, three test-tubes labelled X, Y and Z were half-filled with dilute hydrochloric acid. A
different metal was added to each test-tube. After a few minutes the following observations were made.
In tube X, bubbles slowly rose to the surface. In tube
Y, there was a rapid release of bubbles. In tube Z, no
bubbles were produced.
Which three metals match the observations?
