★ Simple definition of a chemical equation :-

A chemical equation is simply an equation which represents a chemical reaction. A chemical equation represnts a chemical reaction in the form of symbols and formulae. Every chemical equations has two parts - the reactant part & the product part. These two parts are separated by an arrow.

● Reaction 1 :-

Hydrogen gas combines with nitrogen gas to form ammonia :-

$\bold{3H_2(g)+N_2(g)----)2NH_3(g)}$

● Reaction 2 :-

Calcium hydroxide solution combines with carbon dioxide to form calcium carbonate and water :-

$\bold{Ca(OH)_2(aq)+CO_2(g)----)CaCO_3(s)+H_2O(l)}$

● Reaction 3 :-

Aluminium metal reacts with steam to form aluminium oxide and hydrogen gas :-

$\bold{2Al(s)+3H_2O(g)----)Al_2O_3(s)+3H_2(g)}$

● Reaction 4 :-

Manganese dioxide when heated with aluminium powder forms manganese and aluminum oxide :-

$\bold{3MnO_2(s)+4Al(s)----)3Mn(l)+2Al_2O_3(s)+heat}$

● Reaction 5 :-

Potassium metal reacts with water to give potassium hydroxide and hydrogen gas :-

$\bold{2K(s)+2H_2O(l)----)2KOH(aq)+H_2(g)}$

● Reaction 6 :-

Barium chloride reacts with sodium sulphate to form barium sulphate and sodium chloride :-

$\bold{BaCl_2(aq)+Na_2SO_4(aq)----)2NaCl(aq)+BaSO_4(s)}$

● Reaction 7 :-

Zinc carbonate on heating gives zinc oxide and carbon dioxide gas :-

$\bold{ZnCO_3(s)----)ZnO(s)+CO_2(g)}$

● Reaction 8 :-

Hydrogen gas is passed over heated copper oxide to form copper and steam :-

$\bold{CuO(s)+H_2(g)----)Cu(s)+H_2O(g)}$

● Reaction 9 :-

Silver combines with sulphur to form silver sulphide :-

$\bold{2Ag(s)+S(s)----)Ag_2S(s)}$

● Reaction 10 :-

Ferrous sulphate on heating gives ferric oxide, sulphur dioxide and sulphur trioxide gas :-

$\bold{2FeSO_4(s)----)Fe_2O_3(s)+SO_2(g)+SO_3(g)}$
