USES OF HYDROCARBONS

In a study conducted by a group of scientists, two sets of bananas were observed. Set A was exposed to ethylene gas, while set B was kept in a controlled environment without exposure to ethylene. After one week, the bananas in set A ripened significantly faster than those in set B. What conclusion can be drawn from this experiment?

• Ethylene gas accelerates the ripening process of bananas.

• Bananas ripen faster when kept in a controlled environment.

• Bananas in set B were exposed to ethylene gas.

• The ripening process of bananas is not affected by ethylene gas.

In a laboratory experiment, two groups of students were asked to investigate the uses of butane gas. Group A used butane as a fuel for camping stoves, while Group B used it to power handheld lighters. After conducting their experiments, both groups concluded that butane gas is effective as a fuel source. What conclusion can be drawn from this experiment?

• Butane gas is only suitable for use in camping stoves.

• Butane gas is effective as a fuel source for both camping stoves and lighters.

• Butane gas is not a suitable fuel for any purpose.

• Butane gas is ineffective

In a study investigating the uses of hydrocarbons, two groups of students conducted experiments. Group A tested the use of propane gas as a fuel for outdoor grills, while Group B investigated the use of ethylene in the production of plastic bottles. After analyzing their results, both groups concluded that hydrocarbons are versatile compounds with multiple applications. What inference can be made from this experiment?

• Propane gas is only suitable for outdoor grills.

• Ethylene is only used in the production of plastic bottles.

• Hydrocarbons have limited applications and are not versatile.

• Hydrocarbons have diverse uses in both household and industrial settings.

In a laboratory experiment, two samples of hydrocarbons were tested. Sample X contained butane, while Sample Y contained ethylene. Sample X was found to be effective as a fuel for portable camping stoves, while Sample Y was used in the production of synthetic fibers. What conclusion can be drawn from this experiment?

• Butane is only used as a fuel for portable camping stoves.

• Ethylene is only used in the production of synthetic fibers.

• Both butane and ethylene have limited applications.

• Butane and ethylene have different but equally important uses in various industries.

In a household experiment, two groups of families tested the effectiveness of hydrocarbons. Group A used propane gas for heating their homes, while Group B utilized ethylene in the ripening of fruits. After analyzing their results, both groups concluded that hydrocarbons are efficient in their respective applications. What inference can be made from this experiment?

• Propane gas is ineffective foe heating homes.

• Ethylene does not affect the ripening of fruits.

• Hydrocarbons have limited uses in households.

• Hydrocarbons are efficient and effective in various household applications.

In a manufacturing plant, two production lines were observed. Line X produced plastic containers using ethylene, while Line Y manufactured synthetic rubber using butadiene. Both lines were found to be operating efficiently, meeting their production targets. What conclusion can be drawn from this observation?

• Ethylene is only used in the production of plastic containers.

• Butadiene is only used in the production of synthetic rubbers.

• Production lines using hydrocarbons are inefficient.

• Hydrocarbons are utilized in the production of various industrial products.

In an agricultural study, two groups of farmers tested the effectiveness of hydrocarbons in crop production. Group A used methane gas as a fertilizer, while Group B utilized ethylene to stimulate fruit ripening. After observing the results, both groups concluded that hydrocarbons play important roles in agriculture. What inference can be made from this study?

• Methane gas is ineffective as a fertilizer.

• Ethylene has no impact on fruit ripening.

• Hydrocarbons are not beneficial in agriculture.

• Hydrocarbons have diverse applications in agricultural practices.

Which of the following is a common application of butene?

• Production of detergents

• Manufacturing of tires

• Fuel for rocket engines

• Extraction of natural gas

How does the use of polyethylene in exfoliating scrubs relate to its properties?

• Polyethylene is included in scrubs to add fragrance and color

• The abrasive properties of polyethylene help to gently exfoliate the skin, making it suitable for use in scrubs

• Polyethylene is used in scrubs to provide a cooling sensation on the skin

• Polyethylene is avoided in scrubs because it causes skin irritation

Why are alkanes commonly used as fuel sources?

• They are highly soluble in water

• They can be easily synthesized in laboratories

• They release large amounts of energy when burned

• They are resistant to oxidation
