  1. Ammonium phosphate

  2. Liqiud oxygen

  3. Liqiud ammonia

  4. Solid $KCl$

Show answer
Correct Option: B
Explanation:

Liquid -fuel rockets most commonly use liquid oxygen and either kerosene or liquid hydrogen. These combinations work well in space and down closer to the ground.

The strong smelling substance added to LPG is:

chemistry rocks and minerals petroleum properties of alkanes petroleum and natural gas

  1. ethyl mercaptan

  2. ethanol

  3. ethanal

  4. ethyl butane

Show answer
Correct Option: A
Explanation:

LPG gas is basically propane and butane, and it is odorless in its natural state. The smell that you notice when there is a leak is actually the stench of an entirely different agent, called ethyl mercaptan ($C _2H _6S$). This substance is added to the gas when it leaves the main storage terminals.

The chemical added to LPG to help detect its leakages is:

chemistry rocks and minerals petroleum properties of alkanes petroleum and natural gas

  1. isobutene

  2. ethylamine

  3. methyl mercaptan

  4. ethyl mercaptan

Show answer
Correct Option: D
Explanation:

LPG gas is basically propane and butane, and it is odorless in its natural state. The smell that you notice when there is a leak is actually the stench of an entirely different agent, called Ethyl Mercaptan (C2H6S). This substance is added to the gas when it leaves the main storage terminals.

The main constituent of LPG is:

chemistry rocks and minerals petroleum properties of alkanes petroleum and natural gas

  1. methane

  2. butane

  3. propane

  4. both B and C

Show answer
Correct Option: D
Explanation:

LPG constitutes both propane and butane in equal percentages.
Liquefied Petroleum Gas or LPG (also called Autogas) consists mainly of propane, propylene, butane, and butylene in various mixtures. It is produced as a by-product of natural gas processing and petroleum refining. The components of LPG are gases at normal temperatures and pressures.
