Front (Question)

State the melting points of ionic substances

Back (Answer)

High

Front (Question)

Explain why ionic substances have high melting points.

Back (Answer)

Strong bonds between oppositely charged ions are hard to break

Front (Question)

Will NaCl(s) conduct electricity?

Back (Answer)

Front (Question)

Will NaCl (aq) conduct electricity?

Back (Answer)

Yes (aq stands for aqueous which means it is dissolved in water)

Front (Question)

Will NaCl (l) conduct electricity?

Back (Answer)

Yes

Front (Question)

What does molten mean?

Back (Answer)

Melted

Front (Question)

Explain why ionic compounds do not conduct electricity when solid

Back (Answer)

Because the ions are not free to move

Front (Question)

Explain why ionic compounds conduct electricity in solution

Back (Answer)

Because the ions are free to move

Front (Question)

Explain why ionic compounds conduct electricity when molten

Back (Answer)

Because the ions are free to move

#10

Front (Question)

What does soluble mean?

Back (Answer)

Dissolves in water

#11

Front (Question)

What does insoluble mean?

Back (Answer)

Does not dissolve in water

#12

Front (Question)

Magnesium carbonate is insoluble. What do you need to do before it will conduct electricity?

Back (Answer)

Melt it

#13

Front (Question)

Sodium fluoride is soluble. Explain what the easiest way for it to conduct electricity is

Back (Answer)

Dissolve it in water because this does not require high temperatures

#14

Front (Question)

Explain why chlorine and fluorine form covalent bonds

Back (Answer)

They are both non-metals

#15

Front (Question)

Complete the sentence: In covalent bonds, electrons are _______________________

Back (Answer)

Shared

#16

Front (Question)

In ionic bonds, electrons are ___________________

Back (Answer)

Transferred

#17

Front (Question)

What is the name given to the structure of diamond, graphite and silicon dioxide?

Back (Answer)

Giant covalent

#18

Front (Question)

How many bonds does each carbon have in diamond?

Back (Answer)

#19

Front (Question)

Explain why diamond has a high melting point

Back (Answer)

Giant structure, Strong covalent bonds between the atoms, requires a lot of energy to break

#20

Front (Question)

Explain why most giant covalent substances do not conduct electricity (3 marks)

Back (Answer)

There are no electrons/ions/charged particles that are free to move

#21

Front (Question)

Explain why graphite conducts electricity

Back (Answer)

Has delocalised electrons between the layers that can move through the graphite

#22

Front (Question)

Explain why graphite can act as a lubricant

Back (Answer)

Weak forces between layers which are free to slide over each other

#23

Front (Question)

What is graphene?

Back (Answer)

One layer of graphite

#24

Front (Question)

What is a fullerene?

Back (Answer)

Substance made of carbon atoms arranged in a cage
