Laughing gas is prepared by heating
Show Hint
Laughing gas is scientifically known as nitrous oxide (N2O).
- $NH_4CI$
- $(NH_4)_2SO_4$
- $NH_4NO_2$
- $NH_4CI + NaNO_3$
The Correct Option is D
Approach Solution - 1
\({NH_4Cl + NaNO_3 -> NH_4NO_3}\)
Now NH4NO3 on heating results in the following reaction:
\({ NH_4NO_3 ->[\Delta] N_2O + 2H_2O}\)
Nitrous oxide is also known as laughing gas. Therefore, the correct answer is Option D)

The Correct Answer is (D)
Real Life Applications
The real-life applications of laughing gas is -
- Laughing gas is used as an anesthetic in dentistry and surgery.
- It is a mild anesthetic that can help to reduce pain and anxiety.
- It is used as a propellant in whipped cream canisters.
- It is a non-flammable gas that can help to create a light and fluffy whipped cream.
- It is also is sometimes used as a recreational drug. It can produce a euphoric feeling and a sense of relaxation.
Question can also be asked as
- What are the ingredients used to prepare laughing gas?
- How is laughing gas prepared?
- What are the real-life applications of laughing gas?
Approach Solution -3
The Correct Answer is (D)
Laughing gas is scientifically known as nitrous oxide (N2O). It is a well-known chemical compound used for medical and recreational use. The synthesis of laughing gas involves a specific reaction between ammonium chloride and sodium nitrate.
- NH4Cl is a white crystalline salt commonly used in various chemical reactions.
- NaNO3 is a white solid compound widely used in fertilizers and industrial processes.
Decomposition Reaction
- During the heating process, NH4Cl breaks down into NH3 (ammonia) and HCl (hydrochloric acid).
- Simultaneously, NaNO3 decomposes into NaNO2 (sodium nitrite) and O2 (oxygen).
- The produced ammonia and hydrochloric acid further react with sodium nitrite to form laughing gas.
Laughing gas, or nitrous oxide (N2O), is synthesized through the heating of NH4Cl and NaNO3. This chemical reaction involves the decomposition of NH4Cl and NaNO3, followed by the subsequent formation of laughing gas.

Concepts Used:
P-Block Elements
- P block elements are those in which the last electron enters any of the three p-orbitals of their respective shells. Since a p-subshell has three degenerate p-orbitals each of which can accommodate two electrons, therefore in all there are six groups of p-block elements.
- P block elements are shiny and usually a good conductor of electricity and heat as they have a tendency to lose an electron. You will find some amazing properties of elements in a P-block element like gallium. It’s a metal that can melt in the palm of your hand. Silicon is also one of the most important metalloids of the p-block group as it is an important component of glass.
P block elements consist of:
- Group 13 Elements: Boron family
- Group 14 Elements: Carbon family
- Group 15 Elements: Nitrogen family
- Group 16 Elements: Oxygen family
- Group 17 Elements: Fluorine family
- Group 18 Elements: Neon family
