Answer 1

Explanation :

(a)
`4NH_3(g)+5O_2(g)\rightarrow 4NO(g)+6H_2O(g)`

This reaction is combustion reaction in which an oxygen react with a molecule to give its corresponding oxides ans water molecule.

(b)
`S_8(s)+8O_2(g)\rightarrow 8SO_2(g)`

This reaction is a redox reaction or oxidation-reduction reaction in which sulfur get oxidized and oxygen get reduced.

(c)
`2Al(s)+3Cl_2(g)\rightarrow 2AlCl_3(s)`

This reaction is a combination reaction in which the two reactants molecule combine to form a large molecule or product.

(d)
`2AlN\rightarrow 2Al(s)+N_2(g)`

This reaction is a decomposition reaction in which a large molecule or reactant decomposes to give two or more molecule or products.

(e)
`BaCl_2(aq)+Na_2SO_4(aq)\rightarrow BaSO_4(s)+2NaCl(aq)`

This reaction is a double displacement reaction in which the cation of two reactants molecule exchange their places to give two different products.

(f)
`2Cs(s)+Br_2(l)\rightarrow 2CsBr(s)`

This reaction is a combination reaction in which the two reactants combine to form a large molecule or product.

(g)
`KOH(aq)+HCl(aq)\rightarrow H_2O(l)+KCl(aq)`

This reaction is a double displacement reaction in which the cation of two reactants molecule exchange their places to give two different products.

(h)
`2C_2H_2(g)+5O_2(g)\rightarrow 4CO_2(g)+2H_2O(l)`

This reaction is combustion reaction in which a hydrocarbon react with an oxygen to give carbon dioxide and water as a products.
