Metals

Question 30
Describe one way of comparing the reactivity of two metals.
One way of comparing the reactivity of metals is to conduct a
number of tests on samples of the two metals (with equal
surface area).
Samples of the first metal would be left exposed to oxygen,
then heated in a Bunsen Burner.
Then the sample would be placed in three test tubes of cold
water, hot water and dilute acid.
This would be repeated with the second metal, with all
conditions being kept the same (tests done at the same
temperature, the same acid with the same concentration
etc).
The more tests in which a reaction was detected, the more
reactive the metal is.
Alternatively, the reactivity of metals could be compared by
comparing the first ionisation energies of the two.
The less reactive metal would be the one with the higher
first ionisation energy.

Question 31
Explain the term smelting in reference to copper extraction
Smelting refers to the extraction of a metal by heating it to
extremely high temperatures to produce a molten material
from which the pure metal can be obtained.
For copper, the concentrated ore is heated in the presence
of silica (sand) at 1100o
C to produce Copper (I) Sulfide (CuS)
and Iron Silicate (FeSiO3) which is discarded.
The copper sulfide is then heated again to remove the
sulfide in air to produce copper oxides which reacts with
unreacted copper sulfide to produce pure copper.

Question 32
The effectiveness of a nitrogen fertilizer is determined
mainly by its mass %N. Rank the following fertilisers in terms
of their effectiveness: potassium nitrate, ammonium nitrate
and ammonium sulfate.

Question 33
Aluminium can react with alkalis as well as with acids.
(a) Balance the equation for the reaction between sodium
hydroxide solution and aluminium.
(b) How could you be sure that the bubbles produced
during this reaction were bubbles of hydrogen.

Question 34
Outline some ancient or present uses of copper, and some
uses of one of its alloys.
Copper: ornaments, tools, weapons, cooking implements,
water pipes, electric wires
Bronze: cutting tools, armour, statues, bells, statues
Brass: knobs, screws
