2.24 describe the reactions of dilute hydrochloric and dilute sulphuric acids with magnesium, aluminium, zinc and iron

2.24 •acid + metal = salt + hydrogen 

                  •metals above hydrogen in the reactivity series will react with acids to form a salt 

                            •the higher the metal is in the reactivity series, the more violent it is 

                                      •these are all exothermic
