Front (Question)

Redox reactions

Back (Answer)

Reactions involving simultaneous oxidation and reduction

Front (Question)

Oxidation

Back (Answer)

The gain of oxygen, or loss of hydrogen, or loss of electrons

Front (Question)

Reduction

Back (Answer)

Gain of hydrogen, or loss of oxygen, or gain of electrons

Front (Question)

Metal physical properties

Back (Answer)

• good conductors (thermal/electrical) • malleable and ductile • usually have high mp and bp

Front (Question)

Non-metal physical properties

Back (Answer)

• poor conductors (electricity and thermal) except graphite • brittle • usually low mp and bp

Front (Question)

Metal + acid

Back (Answer)

Metal + acid —> hydrogen + salt

Front (Question)

Cold water and metal reactions

Back (Answer)

Only very reactive metals react with it (K, Na, Ca)to form metal hydroxide and hydrogen

Front (Question)

Metals and steam reaction

Back (Answer)

Some metals (Mg) react with steam to form metal oxide and hydrogen

Front (Question)

Why is aluminium used in aircraft

Back (Answer)

It has low density

#10

Front (Question)

Why is aluminium used in overhead electrical cables

Back (Answer)

It has low density and good electrical conductivity

#11

Front (Question)

Why is aluminium used in food containers

Back (Answer)

It resists corrosion

#12

Front (Question)

Why is copper issued in electrical wiring

Back (Answer)

It has very good electrical conductivity

#13

Front (Question)

Alloy

Back (Answer)

A mixture of metal with other elements

#14

Front (Question)

What is brass made of

Back (Answer)

Copper and zinc

#15

Front (Question)

What is stainless steel made of

Back (Answer)

Iron, chromium, nickel, and carbon

#16

Front (Question)

How do alloys compare to pure metals

Back (Answer)

Alloys are usually harder, stronger and more useful

#17

Front (Question)

What is stainless steel used in cutlery

Back (Answer)

It is hard and resists rusting

#18

Front (Question)

How are alloys harder than pure metals

Back (Answer)

Different sized atoms in alloys prevent layers from sliding over each other

#19

Front (Question)

Reactivity series order

Back (Answer)

Potassium, sodium, calcium, magnesium, aluminium, carbon, zinc, iron, hydrogen, copper, silver, gold

#20

Front (Question)

How is reactivity related to ion formation

Back (Answer)

More reactive metals form positive ions more easily

#21

Front (Question)

Which metals react with cold water

Back (Answer)

Potassium, sodium and calcium

#22

Front (Question)

Which metal reacts with steam but not cold water

Back (Answer)

Magnesium

#23

Front (Question)

Which metals react with dilute HCl acid

Back (Answer)

magnesium, zinc, iron

#24

Front (Question)

How can you deduce an order of reactivity

Back (Answer)

By comparing experimental results of displacement or acid/water reactions
