#1
Front (Question)

extracting metal depends on

Back (Answer)

-easiness of extraction from ore -amount of metal ore contains -changing demands for metal

#2
Front (Question)

metal + water observations of recation

Back (Answer)

-flame -fizz -hydrogen gas -hydroxide made

#3
Front (Question)

how to check for hydrogen

Back (Answer)

lighted splint will make a pop sound if h2 is present

#4
Front (Question)

Reactivity series above carbon

Back (Answer)

-K -Na -calcium -mg -aluminium

#5
Front (Question)

Reactivity series above hydrogen

Back (Answer)

-zn -fe -tin -pb

#6
Front (Question)

Reactivity series below hydrogen

Back (Answer)

-cu -silver -gold -platinum

#7
Front (Question)

Reduction of oxide by carbon

Back (Answer)

• c will displace less reactive metal • forming metal and co2 -chemical reduction occurs -carbon = reducing agent

#8
Front (Question)

reducing agent

Back (Answer)

removes oxygen by being oxidised

#9
Front (Question)

Reduction of oxide by hydrogen

Back (Answer)

-more costly than C -less common to use -forms water and metal

#10
Front (Question)

when is hydrogen used as a reducing agent

Back (Answer)

-when carbon is likely to react with a metal to form a compound -instead of the O2

#11
Front (Question)

electrolysis

Back (Answer)

used to extract metals more reactive than carbon

#12
Front (Question)

salt

Back (Answer)

compound formed when H2 in an acid is wholly/partially replaced by metal ions

#13
Front (Question)

Formula for metal + acid

Back (Answer)

metal + acid —> salt + hydrogen

#14
Front (Question)

all acids are

Back (Answer)

aqueous

#15
Front (Question)

how can a sample of salt be obtained after a reaction

Back (Answer)

crystallisation

#16
Front (Question)

metal + acid = redox reaction

Back (Answer)

-metal = loses electrons -hydrogen = gains electrons

#17
Front (Question)

bases

Back (Answer)

compounds that neutralise acids

#18
Front (Question)

alkalis

Back (Answer)

soluble bases

#19
Front (Question)

eg of bases

Back (Answer)

metal oxides

#20
Front (Question)

Formula for neutralisation

Back (Answer)

acid + base —> salt + water

#21
Front (Question)

What ions do acids produce

Back (Answer)

-hydrogen ions -H+

#22
Front (Question)

What ions do alkalis produce

Back (Answer)

-hydroxide ions -OH-

#23
Front (Question)

H+ and OH- react to produce

Back (Answer)

water

#24
Front (Question)

Formula for acid + ammonia solution

Back (Answer)

acid + ammonia solution —> ammonium salt + water
