MISCELLANEOUS AND USEFUL CHEMICAL COMPOUNDS (Part-IV)

The main component of natural gas is methane (CH₄). It is a flammable organic gas. Due to being flammable, it is used as a fuel.

Nitrous oxide (N₂O) is also called laughing gas. Smelling it in excessive quantity leads to a state of unconsciousness. For this reason, this gas is also used as an anesthetic. Dentists use nitrous oxide gas for painless therapy.

Gobar gas is produced by the decomposition of biomass such as dung, excreta, urine, etc. For its construction, filling the above substances in a tank made in a big pit and letting them rot in a closed environment, due to which Gobar gas, whose main component is methane, starts to be generated in a few days.

Quartz is a widely found mineral on Earth, the main component of which is silicon dioxide (SiO₂). Quartz is piezoelectric in nature, that is, when pressure is applied to its crystal, positive and negative charges are generated at its ends. Properly cut plates of quartz are used for frequency control in radio, television, and other electronic communication equipment and in crystal-controlled clocks.

Marsh gas is also called methane gas. Methane is an organic compound, the primary constituent of natural gas. It is a flammable gas and starts coming out of coal mines, due to which there is a possibility of explosions in these mines.

Emerald is a precious gemstone usually of green color. It is a member of the beryl mineral family. Its chemical formula is [Be₃Al₂Si₆O₁₈]. That is, emerald is a combination of beryllium, aluminium, silicon, and oxygen.

Aluminium oxide, silica, and limestone (CaCO₃) are used to make toothpaste, but galena (PbS) or lead sulfide is not used in it. It is a toxic substance for the body.
