Which statement about petroleum fractions is correct?
A. All petroleum fractions are used as fuels.
B. Gas oil is used to make bottled gas for heating.
C. Hydrocarbons in diesel have higher boiling points than hydrocarbons in
gasoline.
D. Molecules in kerosene are larger than molecules in fuel oil.

Answers

Answer 1

Answer: It is either C. or D.

Explanation: I did some reading about it and it talks about fuel but I know that it didn’t say all of them are used as fuels.  maybe I’m wrong

Answer 2

Petroleum is composed of hydrocarbons of various chain length. Different products can be extracted from petroleum but all products cannot be used as fuel.

Hydrocarbons in diesel have higher boiling point than that of gasoline.

What is petroleum?

Petroleum is a naturally occurring crude liquid mixture of hydrocarbons. Petroleum can be fractionated to different components such as gasoline, kerosene, diesel etc.

Each fraction vary in the number of carbons and hydrogens in it or called the difference in chain length. Kerosene contains 8-16 carbons where as gasoline and diesel have more carbons.

Not all products of petroleum fractionation can be used as fuel. Some of them with effective quality is taken as fuels.

The boiling point of hydrocarbons in diesel is greater (about 130-380 degree Celsius) than the hydrocarbons in gasoline which is having boiling point in he range 30-225 degree Celsius.

Therefore, the statement C is correct.

Consider an ice cube and a hot radiator. Which has the higher thermal energy?

the ice cube

the radiator

Answers

The answer to your question is the radiator

The thermal energy of a material increases with temperature. Therefore, the radiator  has the higher thermal energy.

What is thermal energy?

When the temperature rises, a type of energy called thermal energy is produced. The amount of thermal energy usually directly inversely proportional to the object's change in temperature. Thermal energy takes the form of heat.

The thermal energy of a material increases with temperature. The quicker motions of the substance's atoms and molecules are what cause thermal energy to grow as temperature rises.

In some cases, a substance's molecules will separate from one another and leave because the temperature is just so high. Unexpectedly, thermal energy also affects the states of matter. The radiator  has the higher thermal energy.

Therefore, the radiator has the higher thermal energy.

a solution of HCI contains 36 percent HCI,by mass and calculate the mole fraction of HCI in the solution?​

Answers

Explanation:

You have a solution that contains 36 g HCl dissolved in 64 g water

Molar mass HCl = 36.45 g/mol

Mol HCl in 36 g = 36 g / 36.45 g/mol = 0.9876 mol

Molar mass H2O = 18 g/mol

Mol H2O in 64 g = 64 g / 18 g/mol = 3.5556 mol

Total mol = 0.9875 + 3.5556 = 4.5431 mol

Mol fraction HCl = 0.9876 mol / 4.5431 mol = 0.2174

Mol fraction H2O = 3.5556 / 4.5431 = 0.7826

The answer should have 2 significant digits:

Mol fraction HCl = 0.22

Mol fraction H2O = 0.78

How do models help scientists study atomic composition?

Answers

Models can be used to represent a process or show the composition of a material. For example, a model of an atom shows what matter is made out of and how it is composed. Scientists have been using models since ancient times to help explain the world around us. Models help you understand something that you cannot see or touch by making it visible or giving it a form that you can physically explore. In this case, the model lets scientists explore atoms without having to use an electron microscope. This method provides them with up-close images from different angles so they can learn about their properties in detail.

2. Why was sud production used to assess the effectiveness of the synthesized soaps?

Answers

Answer:

Soap is effective as a cleaning agent because it is amphiphilic; it is partly polar and partly nonpolar. ... The sodium ion of the soap is replaced by one of these new ions, and the resulting salt is no longer soluble.

Soap seems to be amphiphilic, or partially polar as well as partially nonpolar, it works well as a cleaning agent. Several of these newfound ions take the place of such soap's sodium ion, rendering the salt insoluble.

What is Soap?

Long chain fatty acids are salts of sodium and potassium that have a cleaning effect in the water. referred as soap They should be used as cleaning agents to get rid of oil and filth from garments and skin. As an illustration, stearic, oleic, as well as palmitic acids are used to create sodium stearate, sodium oleate, respectively sodium palmitate.

What is cleaning agent?

Cleaning agents, often known as hard-surface cleansers, are things that are used to get rid of debris from surfaces, such as dust, stains, foul odors, and clutter. Health, aesthetics, odor removal, and stopping the transfer of dirt and toxins to oneself or others will be among the goals of cleaning products.

Because soap can serve as an emulsifying agent, it would be a superior cleanser. An emulsifier has the ability to mix two immiscible liquids together.

In a chemical equation, the subscript numbers next to each element's symbol tell us how many atoms of that element are in the substance. So, for example, in H₂O, there are 2 atoms of hydrogen since there is a "₂" next to the H.

What's next to our H in C₄H₉? It looks like "₉," so we can determine that there are 9 hydrogen atoms in C₄H₉ (which is butyl, by the way).

How do atomic and molecular interactions explain the properties of matter that we see and feel

Answers

The atomic and molecular interactions unveil the bulk properties of matter in our environment by ways of the fact that everything in the whole universe is made of either atoms, molecules or even ions

How matter is made up of atoms and molecules?

It has been proven practically everything in the whole universe is matter and everything which interact with matter is also matter. This explains to us the reasons why matter could be atoms, molecules or ions.

That being said, some substances (matter) is made up of atoms of elements, some made up of molecules or atoms and molecules and others ions or both. However, matter is anything which has mass and occupies space.

In conclusion, we can now conclude from the explanation above that the properties of matter are as a result of the interaction which exists between matter at the atomic and molecular level.
