what is the word equation for the reaction of magnesium with oxygen
magnesium + oxygen → magnesium oxide
what happens when a metal reacts with oxygen
we form the metal oxide
what is the product of the reaction between iron and oxygen
iron oxide
what is gaining oxygen called
an oxidation reaction
in the equation magnesium + oxygen → magnesium oxide, what is happening to the magnesium?
it has been oxidised
What happens when metals react with oxygen
we form the metal oxide and an oxidation reaction takes place
What can metal oxides do to become a metal
lose oxygen
what are reduction reactions
where metal oxides lose oxygen to become metal
iron oxide + carbon →
iron + carbon dioxide
metal + water →
metal hydroxide + hydrogen
metal + acid →
salt + hydrogen
acid + base (metal oxide/hydroxide) →
salt + water
metal carbonate + acid →
salt + water + carbon dioxide
what salt does hydrolich acid always make
chloride salt
what salt does sulfuric acid always make
sulfate salt
what salt does nitric acid always make
nitrate salt
what happens when a metal reacts with an acid
it creates a salt that takes both the name of the metal and name of the acid’s salt
