Explain what is meant by electrolysis
_
Describe the test to show that a gas is chlorine
_
Write the balanced equation for the reaction of silver
nitrate solution, AgNO3
,
with dilute hydrochloric acid to form silver chloride, AgCl,
and nitric acid
_
Alkenes are unsaturated hydrocarbons.
State what is meant
by unsaturated.
_
Propane and propene are bubbled through separate samples of
bromine water.
Describe what you
would see in these tests
_
In industry, long chain hydrocarbon molecules are cracked to
form shorter chain
hydrocarbon molecules.
Explain why this
process is important.
_
The percentage of carbon dioxide in the Earth’s atmosphere
today is less than
that in the Earth’s earliest atmosphere.
Explain what has
caused the percentage of carbon dioxide to decrease.
_
Carbon dioxide and other gases in the atmosphere help to
keep the Earth
warm.
State how these gases
keep the Earth warm
_
Describe the test to show that a gas is oxygen
_
Metal oxides react with acids to produce salts and water.
Dilute sulfuric acid
was added to magnesium oxide.
State the name of the
salt formed.
_
Explain what you understand by the term alloy
_
Explain, in terms of their structures, why magnalium is
stronger than pure
aluminium.
_
Limestone is a natural form of calcium carbonate.
Explain why calcium
carbonate can be used to treat waste gases produced in
coal-fired power stations.
_
If calcium carbonate is heated strongly it decomposes to
calcium oxide and
carbon dioxide.
Write the balanced
equation for this reaction.
_
The formula of a molecule of propene is C3
H6
.
Draw the structure of
a molecule of propene, showing all covalent bonds.
_
Methane burns in oxygen to form carbon dioxide and water.
Write the balanced
equation for this reaction
_
Natural gas is mainly methane.
A gas with similar
composition, known as bio-methane, can be produced from
plants grown specifically for this purpose.
Describe the
advantages and disadvantages of using bio-methane rather than
natural gas as a source of energy.
