Question

On heating hydrazoic acid form.
A) $N{H_3}$
B) ${N_2} + N{H_3}$
C) ${N_2}{H_4} + N{H_3}$
D)${H_2} + 3{N_2}$

Answer 1

Hint:First, we understand the decomposition reaction.
We must remember that if a compound breaks all the way down to 2 or a lot of substances then it is said to be a decomposition reaction. The final equation for the reaction is,
$AB \to A + B$

Complete step by step answer:
The acid is sometimes shaped by natural action of an azide salt like metal azide. Generally sodium azide in water has trace amounts of azomite in balance with the azide salt; though introduction of a stronger acid will convert the first species in solution to hydrazoic acid $\left( {H{N_3}} \right)$. The pure acid could also be obtained by a fractional process as a very explosive colorless liquid with an unpleasant smell. The decomposition of hydrazoic acid forms hydrogen and nitrogen molecules.
The decomposition of hydrazoic acid, triggered by shock, friction, spark, and so forth goes as follows:
$2H{N_3}\xrightarrow{\Delta }{H_2} + 3{N_2}$
Therefore, the option D is correct.

Additional Note:
Now we discuss how thermal and electrolytic decomposition reactions differ from each other.
-Thermal decomposition reaction: The reaction that could be activated by the thermal energy is outlined as a thermal decomposition reaction. The decomposition of carbonate is an appropriate example of a thermal decomposition reaction. We can write a chemical equation for the thermal decomposition of calcium carbonate as,
$CaC{O_3}\xrightarrow{\Delta }CaO + C{O_2}$
-Electrolytic decomposition reaction: The reaction that may be activated by the electricity is outlined as associated in an electrolytic decomposition reaction. The electrolysis of water is an appropriate example of an electrolytic decomposition reaction. We can write a chemical equation for the electrolytic decomposition of water as,
$2{H_2}O \to 2{H_2} + {O_2}$

Note:
Now we can see the difference between the chemical displacement and decomposition reaction as,
-Chemical displacement:
We must remember that in the chemical reaction if one metal replaces another compound form a new product called chemical displacement reaction.
Example: \[Zn + 2HCl \to ZnC{l_2} + {H_2}\]
-Chemical decomposition:
We must know that the chemical reaction in which reactants decomposes into two or more products called chemical decomposition
Example: $CaC{O_3}\xrightarrow{\Delta }CaO + C{O_2}$.
