    When sodium nitrate is heated above \[\text{600}{{\,}^{\text{o}}}\text{C,}\]then:

    A)  only \[\text{N}{{\text{a}}_{\text{2}}}\text{O}\]is formed

    B)  only \[{{\text{N}}_{2}}\]is formed

    C)  only\[{{\text{O}}_{\text{2}}}\] is formed     

    D)  all are formed

    Correct Answer: D

    Solution :

     On heating \[\text{NaN}{{\text{O}}_{\text{3}}}\]above\[\text{600}{{\,}^{\text{o}}}\text{C}\,\text{N}{{\text{a}}_{\text{2}}}\text{O,}\,{{\text{O}}_{\text{2}}}\] and \[{{\text{N}}_{2}}\]all is obtained as: \[4NaN{{O}_{3}}\xrightarrow{800{{\,}^{o}}C}2N{{a}_{2}}O+5{{O}_{2}}+2{{N}_{2}}\]
