Why does silicon dioxide have a high melting and boiling point? - ANSWER-
Silicon dioxide has a high melting and boiling point because it is made up of
strong covalent bonds and a lot of heat energy is required to break its bonds
What element is Graphite made of? - ANSWER-Graphite is formed from
carbon
In Graphite how many bonds does carbon form? - ANSWER-In Graphite each
carbon atom forms three covalent bonds
Describe the structure of Graphite - ANSWER-Graphite has a giant covalent
molecular structure it contains many layers of carbon atoms each carbon atom
covalently bonded to three other carbon atoms, the layers are held by weak
forces between them
Does graphite have a high or low melting and boiling point? - ANSWER-
Graphite has a high melting and boiling point
,Why does graphite have a high melting and boiling point? - ANSWER-Graphite
has a high melting and boiling point because it is made up of strong covalent
bonds and a lot of heat energy is required to break its bonds
Is graphite a good or bad conductor of heat and electricity? - ANSWER-
Graphite is a good conductor heat and electricity
What is the pH scale? - ANSWER-The pH scale is a scale from 1-14 that tell us
the acidity or alkalinity of a solution
What do colours towards red show? - ANSWER-Colours towards red show an
acidic solution
What do colours towards purple show? - ANSWER-Colours towards purple
show an alkali solution
What happens when you react an acid with an alkali? - ANSWER-A
neutralisation reaction occurs, the hydrogen ions react with hydroxide ions to
form water
What element do all acids contain? - ANSWER-All acids contain hydrogen
What is the word equation for the reaction between an acid and a metal? -
ANSWER-Acid + Metal → Salt + Hydrogen
What are the endings of salts produced from hydrochloric acid? - ANSWER-
Hydrochloric acid produces salts that end in -chloride
What are the endings of salts produced from sulfuric acid? - ANSWER-Sulfuric
acid produces salts that end in -sulfate
,What are the endings of salts produced from nitric acid? - ANSWER-Nitric acid
produces salts that end in -nitrate
What is formed when hydrochloric acid reacts with magnesium? - ANSWER-
Hydrochloric Acid + Magnesium → Magnesium Chloride + Hydrogen
What is formed when sulfuric acid reacts with iron? - ANSWER-Sulfuric Acid
+ Iron → Iron Sulphate + Hydrogen
What happens to the elements in the reaction between an acid and metal? -
ANSWER-The metal displaces the hydrogen from the acids to form a salt and
the hydrogen is released as a gas
What is formed when an acid reacts with a base? - ANSWER-Acid + Base →
Salt + Water
What is formed when an acid reacts with an alkali? - ANSWER-Acid + Alkali
→ Salt + Water
What type of ions do salts contain? - ANSWER-Salts contain a positive ion
which comes from the base or alkali and a negative ion which comes from the
acid
Why is graphite a good conductor of heat and electricity? - ANSWER-Graphite
is a good conductor heat and electricity because when the carbon atoms bond
together each carbon atom has an electron that is not in a covalent bond, these
delocalised electrons can move and they can conduct heat and electricity
What are delocalised electrons? - ANSWER-Delocalised electrons are electrons
that can move meaning they can conduct heat and electricity
, Describe the texture of graphite - ANSWER-Graphite is soft and slippery
Why is graphite soft and slippery? - ANSWER-Graphite is soft and slippery
because graphite is made up of hexagonal rings in on top of each other and there
are no covalent bonds between the layers so the layers can slide making
graphite soft and slippery
Describe the structure of graphene - ANSWER-Graphene is a single layer of
graphite and it is one atom thick
Is graphene a good or bad conductor of electricity? - ANSWER-Graphene is a
good conductor of electricity
What is a displacement reaction? - ANSWER-Displacement Reactions are
reactions in which a more reactive element replaces a less reactive element in
one of its compounds or in a solution
What is needed for a displacement reaction? - ANSWER-The element being
displaced need to be less reactive than the element that is displacing it
Show an example of a displacement reaction - ANSWER-Magnesium + Iron
Oxide → Magnesium Oxide + Iron
Have the iron atoms been oxidised or reduced? - ANSWER-The iron atoms
have been reduced because they lost electrons
Have the magnesium atoms been oxidised or reduced? - ANSWER-The
magnesium atoms have been oxidised because they gained oxygen
How is carbon used to extract elements? - ANSWER-The carbon displaces the
less reactive element
