What are some ways that propane, butane, gasoline, diesel, and kerosene can be compared?

Answers

Answer 1

Answer:

Propane and butane are pure substances, which means that each one of them is made of only one type of molecule—propane molecules or butane molecules. In contrast, gasoline, diesel, and kerosene are not pure substances; they are mixtures of more than one substance.

Explanation:

Hope it is helpful...

Answer 2

Propane, butane, gasoline, diesel and kerosene are all hydrocarbons. They  can be produced from petroleum. All these are used as fuels.

What are hydrocarbons ?

Hydrocarbons are organic compounds containing  C-C backbone and C-H bonds, These compounds are composed of carbons and hydrogens. Different function groups can be added to the hydrocarbons to form  various organic compounds such as acids, esters , aldehydes, ketones etc.

Methane is the first hydrocarbon in the hierarchy based on number of carbons. Propane is third in this series since it contains 3 carbons and butane is 4th one. Gasoline, diesel and kerosene are all hydrocarbons with different carbon numbers.

All these are obtained  as a byproduct of petroleum. These are used as fuel in vehicles and house holds.  The difference in them is the number of carbon and hydrogen.

In which material would the particles be closest together?

Answers

I think air but if wrong sorry

Answer:

Brick

Explanation:

The distance between particles is best determined by density. So, to find which material has the most compacted particles, we need to find which material has the highest density. Solids will always have the highest densities, so Brick would have the particles that are closest together.

Answers

Answer:

0.17×10⁻³ mol

Mass = 0.00476 g

Explanation:

Given data:

Number of molecules of N₂ = 1 ×10²⁰ molecules

Number of moles of N₂ = ?

Mass in gram of N₂ = ?

Solution:

1 mole of any substance contain 6.022×10²³ molecules

1 ×10²⁰ molecules× 1 mol /6.022×10²³ molecules

0.17×10⁻³ mol

Mass in gram:

Mass = number of moles × molar mass

Mass = 0.17×10⁻³ mol × 28 g/mol

Mass = 4.76×10⁻³  g

Mass = 0.00476 g

Two substances in a mixture differ in density and particle size. theses properties can be used to

Answers

Answer:

option 1. Two substances in a mixture differ in density and particle size. These properties can be used to separate the substances. These properties can be manipulated in order to have a better separation between the two substances.

Explanation:

Answer:

Two substances in a mixture differ in density and particle size. These properties can be used to separate both of them using the separating funnel or using filtration (filter paper).

Explanation:

Since their densities are different, one substance should float above the other in the mixture which allows for the separating funnel to let the substance sinking below (with the heavier density) to flow out first before changing the beaker to let the lighter substance flow out.

The substance with a bigger particle size would not be able to pass through the filter paper unlike the substance with the smaller particle size as the filter paper's pores is not big enough for it to pass through, separating both substances (with one on the paper and the other outside the filter paper, preferably in the beaker placed below the paper).

Tanisha is mixing powdered orange drink mix into a cup. She wants to make sure the orange taste is strong, so she adds a lot of powdered mix. As she is mixing, she notices that the powdered mix starts to float around in the water in clumps, and some settles on the bottom of the cup. Predict why this would happen.
A.
The powder is too old to dissolve in the water.
B.
No more powder will dissolve in the water.
C.
The powder needs to be shaken to fully dissolve.
D.
The powder does not fully dissolve because the water is too warm.

Answers

Answer:

B. No more powder will dissolve in the water.

Explanation:

If a lot of powder is added to the water, then a fully saturated solution would be created. This means that no matter how much more powder is added or how strong the mix is shaken, no more powder will disolve. The powder will instead remain in solid form in the solution.

Answer:

Heat up the water first because it increases solubility of the powdered mix.

3. What is the energy of a photon whose frequency is 5.2 x 1015 Hz? Use the equation: E = hxv
h= 6.626 10-34 J xs
4. What is the frequency of radiation whose wavelength is 2.40 x 105 cm? v=c+X
C= 3 x 108m/s

Answers

Answer:

3. 3.45×10¯¹⁸ J.

4. 1.25×10¹⁵ Hz.

Explanation:

3. Determination of the energy of the photon.

Frequency (v) = 5.2×10¹⁵ Hz

Planck's constant (h) = 6.626×10¯³⁴ Js

Energy (E) =?

The energy of the photon can be obtained by using the following formula:

E = hv

E = 6.626×10¯³⁴ × 5.2×10¹⁵

E = 3.45×10¯¹⁸ J

Thus, the energy of the photon is 3.45×10¯¹⁸ J

4. Determination of the frequency of the radiation.

Wavelength (λ) = 2.4×10¯⁵ cm

Velocity (c) = 3×10⁸ m/s

Frequency (v) =?

Next, we shall convert 2.4×10¯⁵ cm to metre (m). This can be obtained as follow:

100 cm = 1 m

Therefore,

2.4×10¯⁵ cm = 2.4×10¯⁵ cm × 1 m /100 cm

2.4×10¯⁵ cm = 2.4×10¯⁷ m

Thus, 2.4×10¯⁵ cm is equivalent to 2.4×10¯⁷ m

Finally, we shall determine the frequency of the radiation by using the following formula as illustrated below:

Wavelength (λ) = 2.4×10¯⁷ m

Velocity (c) = 3×10⁸ m/s

Frequency (v) =?

v = c / λ

v = 3×10⁸ / 2.4×10¯⁷

v = 1.25×10¹⁵ Hz

Thus, the frequency of the radiation is 1.25×10¹⁵ Hz.

Tectonic Theory. Student 3 describes "glacial evidence indicates that different continents were once connected near the South Pole."

What is plate Tectonic Theory?

The widely recognized scientific hypothesis known as plate tectonics states that the Earth's lithosphere was made up of many major tectonic plates that have already been gently migrating since around 3.4 billion years ago.

What is the South Pole?

The south pole would be one of two locations on Earth's surface at which the planet's axis of rotation crosses it. It is often referred to as one of the Geographic south pole, Terrestrial South Pole, and 90th Parallel South.

The fossil record is such sort of evidence that has been used to support the Claim of Continental Drift. On the coastlines of many continents, fossils of specific kinds of plants, as well as animals have been discovered in rocks that are comparable in age, indicating that the continents had been connected.

What are redox reactions?

Redox reactions are the reactions in which reduction reaction and oxidation reaction happens simultaneously. The term ‘redox’ is a short form of reduction-oxidation. All the redox reactions can be broken down into two different processes: a reduction process and an oxidation process.

The loss of electrons and the corresponding increase in the oxidation state of a given reactant is called oxidation. The gain of electrons and the corresponding decrease in the oxidation state of a reactant is called reduction.

For example-

H₂ + F₂ → 2HF

Hydrogen is added to Fluorine gas so Fluorine has been reduced but Hydrogen has been oxidised.

Therefore, Among the following redox conditions those will produce a spontaneous reaction is The sum of the voltages of the half-reactions is positive.

Which property or properties can change when the pressure of a gas changes?

Answers

Answer: This law states that the volume and temperature of a gas have a direct relationship: As temperature increases, volume increases, when pressure is held constant. Heating a gas increases the kinetic energy of the particles, causing the gas to expand

Explanation:

According to this law, a gas's volume and temperature are directly correlated: When pressure is held constant, volume rises as temperature rises. The kinetic energy of the particles in a gas increases when it is heated, which causes the gas to expand.

What rules apply to gases?

According to Boyle's Law, when the temperature and mass are both constant, the volume of a given volume of gas sustained at a constant temperature varies inversely with the applied pressure.

The quantity of gas particles, the volume of the container, and the temperature of the gas all affect the pressure of a gas that is confined. The pressure will rise as the amount of gas particles in a container increases. The pressure will rise as a container's volume increases.
