Additional information

Metals

Question 23
Classify the following as chemical or physical change.
(a) An iron object rusting Chemical ↙
(b) An iodide sample subliming Physical ↙
(c) Dissolving sugar in water Physical ↙
(d) A silver ring darkening Chemical ↙
(e) Candles burning Chemical ↙

Question 24
Is the atmosphere a single chemical or a mixture of
chemicals? If the former, what is its chemical formula?
If the latter, what chemicals is it made of?
It is a mixture of chemicals.
The atmosphere consists mostly of nitrogen gas (78%) and
oxygen gas (21%), with trace amounts of other gases such as
argon (0.9%) and carbon dioxide (0.04%).

Question 25
People have developed techniques to extract useful
substances from mixtures. Identify an example of:
(a) A precious metal that occurs naturally as an element.
Copper, silver, gold, platinum, etc. ↙
(b) A liquid fuel obtained from crude oil.
Octane, hexane, kerosene, diesel fuel, etc. ↙
(c) A salt obtained from a natural source.
Sodium chloride, magnesium chloride ↙
(d) A gas obtained from the air.
Oxygen, nitrogen, argon, etc. ↙

Question 26
A water sample from a creek was analysed to determine the
amount of dissolved solids it contained. The undissolved
solids were removed from the sample before the amount of
dissolved solids were measured.
(a) What techniques can be used to separate the
undissolved and the dissolved solids from the water?
Filtration can be used to separate the undissolved solids, and
evaporation can be used to separate the dissolved solids. ↙
(b) 0.74 g of dissolved solids were obtained from 150 mL of
the water sample. Find the percentage of dissolved solid
in the water by mass.
150 mL of water have a mass of 150 g.
0.74 / 150 = 0.49% dissolved solids ↙

Question 27
Silver nitrate solution was added to 30.16 g of seawater.
The chloride ions in the seawater formed silver chloride, an
insoluble substance. This precipitate was filtered out of the
mixture and its mass was measured to be 9.157 g.
(a) Calculate the percentage of chloride in silver chloride by mass.
(b) Calculate the mass of chloride in the silver chloride precipitate.
(c) Calculate the percentage of chloride in the sample of seawater by mass.

Question 28
Methanol CH3OH melts at –97 C and boils at 65 C.
However, it takes a large amount of energy to separate
methanol into its constituent elements (235 kJ mol–1).
(a) What do the low melting and boiling points of methanol
indicate about the strength of its intermolecular forces?
When methanol melts or boils, the intermolecular forces
holding the molecules together are overcome.
It only takes a small amount of energy to melt or boil
methanol, so its intermolecular forces must be weak.
(b) What does the large energy required to decompose
methanol indicate about the bonds within the molecule?
To decompose a substance, the forces between the atoms
within a molecule must be overcome.
It takes a large amount of energy to decompose methanol,
so the covalent bonds holding together must be strong.
Question 29
Sulfuric acid (dihydrogen sulfate) can react with copper to
form copper (II) sulfate and hydrogen gas.
(a) Write down the chemical formulae of the reactants and
the products.
(b) Is this a physical change or a chemical change?
An acid and a metal produce an ionic substance and a gas.
The products of the change are different substances to the
reactants, so this must be a chemical change.
