The half-life of first order decomposition of NH_(4)NO_(3) is 2.10 hr at 288 K temperature NH_(4)NO_(3)(aq)toN_(2)O(g)+2H_(2)O(l) . If 6.2 of NH_(4)NO_(3) is allowed to decompose, the required for NH_(4)NO_(3) to decompose 90 % is :
Choose the correct set of True/Fasle for following statements: (i) Silver chloride is more soluble in very concentrated sodium chloride solution than in pure water. (ii) The pH of a buffer solution does not change on addition of small amount of an acid or a base. (iii) Addition of NH_(4)Cl does not affect the pH of a solution of NH_(4)OH (iv) Degree of hydrolysis of ammonium acetate does not depend upon the concentration of ammonium acetate solution. (v) A mixture of acetic acid and sodium acetate can act as buffer solution.

When two cotton plugs, one moistened with ammonia and the other with hydrochloric acid, are sumulataneously inserted into opposite ends of a glass tube 87.0 cm long, a white ring of NH_(4)Cl forms where gaseous NH_(3) and gaseous HCl first come into contact.
