Write word equations and then balanced equations for the reaction taking place when

Options

A. dilute sulphuric acid reacts with zinc granules
B. dilue hydrochloric acid reacts with magnesium ribbon
C. dilute sulphuric acid reacts with aluminium powder
D. dilute hydrochloric acid reacts with iron filings

Explanation

(a) Sulphyric acid `+` Zinc `to` Zinc sulphate `+` Hydrogen
`H_(2)SO_(4)+ZntoZnSO_(4)+H_(2)`
(b) Hydrochloric acid `+` Magnesium `to` Magnesium chloride `+` Hydrogen
`2HCl + Mg to MgCl_(2)+H_(2)`
(c) Suphuric acid `+` Aluminium `to` Aluminium sulphate `+` Hydrogen
`3H_(2)SO_(4)+2Al to Al_(2)(SO_(4))_(3)+3H_(2)`
(d) Hydrochloric acid `+` Iron `to` Iron (II) chloride `+` Hydrogen
`2HCL + Fe to FeCl_(2)+H_(2)`
