Q-2

Q.2. What type of chemical reactions are represented by the following equations :-

$$\begin{gathered} \left(a\right)N{H}_4+N{O}_2\to N_2+H_{2}O \\ \left(b\right)AgN{O}_3+NaCl\to AgCl+NaN{O}_3 \end{gathered}$$$$\begin{gathered} \left(a\right)N{H}_4+N{O}_2\to N_2+H_{2}O \\ \left(b\right)AgN{O}_3+NaCl\to AgCl+NaN{O}_3 \end{gathered}$$

Answer 1

Dear Student
1 The above reaction is a REDOX reaction because nitrogen dioxide is reduced to nitrogen gas whereas hydrogen combines with oxygen to form water.
2 This reaction is not the redox reaction. As the oxidation state does not change.

Its a double displacement reaction. Double displacement reactions are the one in which the two reactants react and the positive and negative ions get exchanged. NO₃ ^- goes from Ag⁺ to Na⁺ and Cl^- goes from Na⁺ to Ag^+
