Sulphuric acid `+ Zn rarr` Zinc sulphate + Hydrogen `H_(2)SO_(4) + Zn rarr ZnSO_(4) + H_(2)`
(b) Dilute hydrochloric acid reacts with magnesium ribbon Hydrochloric acid + Magnesium `rarr` Magnesium chloride + Hydrogen
`2HCl + Mg rarr MgCL_(2) + H_(2)`
(c ) Dilute sulphuric acid reacts with aluminium powder
Sulphuric acid + Aluminium `rarr` Aluminium sulphate + Hydrogen
`3H_(2)SO_(4) + 2Al rarr Al_(2)(SO_(4))_(3) + 3H_(2)`
(d) Dilute hydrochloric acid reacts with iron filings.
Hydrochloric acid + `Fe rarr` Iron chloride + Hydrogen `6HCl + 2Fe rarr 2FeCl_(2) + 3H_(2)`
