name the reactivity series in order
potassium
sodium
calcium
magnesium
Aluminium
carbon
zinc
Iron
Tin
Lead
hydrogen
Copper
Silver
Gold
Platinum
elements in the reactivity series that react with water
potassium, sodium, calcium, magnesium, aluminium, zinc, iron
elements that react with steam or acid
potassium, sodium,, calcium - explode when reacted with acid
magnesium, aluminium, zinc, iron - fizz and giving off hydrogen gas
tin and lead - reacts slowly with warm acid
name the equation for reacting a metal with an acid
metal + acid –> metal salt + hydrogen gas
elements that don’t react with acid or water or steam in the reactivity series
copper, silver, gold, platinum
how does displacement reactions work
more reactive elements displace less reactive elements
what is oxidation
loss of electrons, gain of oxygen
what is reduction
gain of electrons, loss of oxygen
what’s a base
