names of reactions

Question 1

what reaction is called the gaining of oxygen?

Answer 1

oxidation
remember to identify this in the test and example may be
magnesium + oxygen —} magnesium oxide
2Mg + o2 —} 2MgO

Question 2

what reaction is the called the loss of oxygen?

Answer 2

reduction
remember to identify this in the test and example may be
iron oxide + carbon monoxide —} iron + carbon dioxide
fe2O3 + 3CO —} 2Fe + 3CO2

Question 3

what is the reaction when a more reactive metal (one that can form ions more easily) replaces a less reactive metal?

Answer 3

a displacement reaction
remember to identify this in a test a example may be
magnesium + copper sulphate —} magnesium sulphate + copper
mg + CuSO4 —} MgSO4 + Cu
the magnesium displaces the copper because its more reactive

Question 4

what is a reversible reaction?
–}
{–

Answer 4

a reaction which can proceed both forwards and backwards (e.g the reactants A+B can combine to give the products C+D and C+D can combine to give A+B)

Question 5

what is a exothermic reaction?

Answer 5

energy transfers to the environment from the reactants

Question 6

what is a endothermic reaction?

Answer 6

energy transfers from the environment to the reactants
