#1
Front (Question)

electric current

Back (Answer)

is the flow of the electrons or ions

#2
Front (Question)

when do ionic compounds conduct electricity?

Back (Answer)

when molten or in solution

#3
Front (Question)

why can’t solid ionic compounds conduct electricity?

Back (Answer)

because the ions aren’t able to move around

#4
Front (Question)

why can dissolved ionic compounds conduct electricity?

Back (Answer)

when it is dissolved the ions separate and are able to move in the solution

#5
Front (Question)

why can molten ionic compounds conduct electricity?

Back (Answer)

the ions are able to move when an ionic compound melts

#6
Front (Question)

how are metals held together?

Back (Answer)

by metallic bonding

#7
Front (Question)

how does metallic bonding occur?

Back (Answer)

• metals have a giant structure of positive ions surrounded by a sea of delocalised electrons • electrostatic attractions between nuclei of positive ions and the electrons

#8
Front (Question)

metallic bonding

Back (Answer)

the electrostatic attractions between the nuclei of the positive ions and the electrons

#9
Front (Question)

why are metals good conductors of electricity and heat?

Back (Answer)

• delocalised electrons move • metals conduct electricity • energy can be transferred through material

#10
Front (Question)

why are metals malleable?

Back (Answer)

the layers of ions in a metal can slide over each other

#11
Front (Question)

what does malleable mean?

Back (Answer)

e.g. metals can be hammered

#12
Front (Question)

what does condensation polymerisation usually involve?

Back (Answer)

two different types of monomer

#13
Front (Question)

what does each monomer in a condensation polymerisation contain?

Back (Answer)

at least two functional groups

#14
Front (Question)

what monomers make up polyesters?

Back (Answer)

dicarboxylic acid monomers + diol monomers

#15
Front (Question)

dicarboxylic acid monomers contain what?

Back (Answer)

two carboxylic acid groups -COOH

#16
Front (Question)

diol monomers contain what?

Back (Answer)

two alcohol groups -OH

#17
Front (Question)

what bond forms when the carboxylic acid group and the alcohol group react?

Back (Answer)

ester bond O=C-O

#18
Front (Question)

what reaction forms polyesters?

Back (Answer)

a condensation reaction and a molecule of water is lost

#19
Front (Question)

biodegradable polyesters are called what?

Back (Answer)

biopolyesters

#20
Front (Question)

biopolyesters

Back (Answer)

can be broken down by bacteria and other living organisms, meaning that they decompose and don’t stay in landfill forever

#21
Front (Question)

state the name of the first four alcohols

Back (Answer)

methanol, ethanol, propanol, butanol

#22
Front (Question)

give two uses of esters?

Back (Answer)

can be used in perfumes and to make food flavourings
