Liquefied Petroleum Gas (LP-Gas) is composed predominantly of which hydrocarbons?

Liquefied Petroleum Gas (LP-Gas) is predominantly composed of propane and butane. These two hydrocarbons are obtained during the refining process of natural gas and crude oil. Both propane and butane have specific properties that make them suitable as energy sources for heating, cooking, and fuel for vehicles.

The characteristics of propane include its capability to vaporize and expand significantly when mixed with air, making it highly efficient for combustion and heating applications. Butane, while similar to propane, has a higher boiling point, making it more suitable for use in milder climates where temperatures do not drop significantly.

The other answer choices contain substances that do not represent the primary components of LP-Gas. Ammonia and ethanol are not hydrocarbons and serve different purposes in various industrial and agricultural applications. Methanol and acetic acid are also not relevant as they are alcohols and carboxylic acids, respectively, and do not form the basis of LP-Gas. Nitrogen and argon are inert gases that do not have energy-producing capabilities and are not applicable in the context of LP-Gas composition.

Thus, recognizing that LP-Gas is primarily composed of propane and butane is crucial for understanding its functionality and application in various industries.
