The reactivity series

Question 1

if something gains _____ its oxidised

what type of reactions involve oxidation?

Answer 1

oxygen

combustion

Question 2

Nam the reactivity series of metals starting with most reactive at top
What is the link between most reactive and oxidation?

Answer 2

K
Na
Ca
Mg
Al
C
Zn
Fe
H
Cu
Ag
Au
most reactive,more likely to lose e to form cations = most likely to oxidise

Question 3

Explain an experiment we can do to check reactivity of metals.
What observations/test can we do to check which is the most reactive?

Answer 3

place pieces of various metals into dilute hydrochloric acid.
more easily metal atom loses outer e,to form cation = more reactive
put a lighted splint into test tube =louder pop -more hydrogen formed =more reactive.
more reactive=faster reaction ,speed of reaction indicated by rate which bubbles given off

Question 4

Some metals react with water
what is the basic reaction produce(word equation)?
Which metal doesn’t react at all with water?

Answer 4

metal + water = metal hydroxide + hydrogen
reactive metals react vigorously
less reactive ones dont react,but do with steam
copper

Question 5

Some metals react with water
what is the basic reaction produce(word equation)?
Which metal doesnt react at all with water?

Answer 5

metal + water = metal hydroxide + hydrogen
reactive metals react vigorously
less reactive ones dont react,but do with steam
copper
