the boiling point Boiling temperature is the point at which a liquid's vapor pressure equals the atmospheric pressure.

When the liquid's vapor pressure equals the air pressure acting on it, the liquid transitions from a liquid state to a gaseous phase. Although boils is a physical transformation, molecules are still not chemically changed.

The line is broken at the substance's boiling point since a liquid's typical boiling point is now between point B and C the temperature where the fluid and gas are already in equilibrium at one atmosphere of pressure, with the resulting liquid vapor pressure being one atmosphere.

Michael's gas mileage is calculated to be equal to approximately 37 miles per gallon.

Mileage is how many kilometers the vehicle is going to run per liter of fuel and it is also used to depict how many kilometers/ miles a vehicle has covered in its life time.

Gas mileage = distance / gas used

In this case, Michael drove 682 miles and used 18.6 gallons of gas, so his gas mileage is:

Gas mileage = 682 miles / 18.6 gallons = 36.67 miles per gallon

Gas mileage ≈ 37 miles per gallon

Therefore, Michael's gas mileage is approximately 37 miles per gallon.

Answer:

Human action has affected the population in quite a negative way. Technological innovations and urbanization gave rise to a high degree of pollution on the land, air and water.

Emission of hydrocarbons from automobiles and factories are known to pollute and cause sicknesses related to the respiratory system thereby shortening the lifespan of humans. Pollution of water bodies also cause death of sea animals and thereby reducing food availability of humans.

Answer: 22 degrees

Explanation:

Most of the information in this question is put there to throw you off- the only important piece of information here is the final temperature of the water.

In a system of say 2, like in this example, whichever object has more energy in the form of heat will transfer that heat to the object with lesser heat if there is an available path to transfer heat between them. Once the two objects are at the same temperature, however, heat can not be transferred from one to another since neither object has more heat than the other to transfer- this is thermal equilibrium.

This question tells us that the system is at thermal equilibrium- when both objects are at the same temperature. Given the temperature of one object, the water, we then know the other object, the metal is the same temperature.

First of all finding the pressure, again we will be assuming an ideal pressure of 1 atm, this will be our total pressure, now we have to find the partial pressure for H2. The partial pressure for H2O is related to its temperature, when it's 40°C we will have a pressure of 55.37 torr, which is 0.0728 atm

Ptotal = Ph2 + Ph2o

1 atm = Ph2 + 0.0728 atm

Ph2 = 0.927 atm

Now we will add this information to our Ideal Gas law formula:

PV = nRT

0.927 * 0.081 = n * 0.082 * 313

0.075 = 25.66n

n = 0.003 moles

H2 = 2.0158g/mol

0.003 moles of H2 = 6.0*10^-3

Carboxylic acids are acidic due to the presence of the carboxyl group. They can react with bases to form salts and water. Alkenes, on the other hand, are not acidic.

Alkenes have a carbon-carbon double bond (-C=C-), while carboxylic acids have a carboxyl group (-COOH). You can identify the functional group by looking at the molecular formula or by using spectroscopic techniques like infrared (IR) spectroscopy.

Carboxylic acids have higher boiling points than alkenes due to the presence of hydrogen bonding between carboxylic acid molecules.

When an acid is dissolved in water it forms hydrogen ions (H+) that combine with water to form the hydronium ion (H3O+) .

Answer:

Acids are substances that when dissolved in water release hydrogen ions, H+(aq). ... When dissolved, bases release hydroxide ions, OH-(aq) into solution. Water is the product of an acid and base reacting. Chemists say that the acid and base cancel or neutralise each other, hence the reaction is known as "neutralisation".

Explanation:

We can convert cyclohexanol to cyclohexene in the presence of a strong acid such as sulfuric acid catalyst in a test tube at 60 oC by heating up the mixture to about 80 oC. This is a dehydration reaction so water is removed  to yield the alkene. A drying agent is used to remove any trace amount of water left in the system. This overall reaction is endothermic.

Also, the reverse is the case when we want to carry out the hydration of cyclohexene to yield cyclohexanol. The overall reaction is exothermic and involves the addition of more water to the alkene and then cooling down the system to about 40 oC.

The interactions that can be explained by hydrogen bonding are:

Hydrogen bonding is a type of intermolecular force that occurs between a hydrogen atom in a polar molecule and a highly electronegative atom, such as nitrogen, oxygen, or fluorine, in a neighboring molecule. It is a relatively strong force and can significantly affect the physical and chemical properties of substances.

In the case of HF and HCl, both molecules are polar, but HF has a higher boiling point due to the stronger hydrogen bonding between its molecules. In ice, the hydrogen bonding between water molecules creates a crystal structure with a characteristic lattice arrangement.

Option D, W3+ (g) → W4+ (g) + e-, requires the most energy for the ionization process.

The ionization interaction that requires the most energy is choice D, where W3+ (g) is ionized to W4+ (g) by the deficiency of one electron. This is on the grounds that the energy expected to eliminate an electron from a particle increments as the particle turns out to be all the more decidedly charged. Hence, it takes more energy to eliminate an electron from W3+ (g) than it does from W+(g), W2+ (g), or W3+ (g).

Choice An includes the expulsion of one electron from an impartial tungsten iota, and choice B includes eliminating an electron from W+. Choice C includes eliminating an electron from W2+. These ionization processes require less energy than choice D in light of the fact that the ionization energy increments as the particle turns out to be all the more emphatically charged. Hence, the ionization energy expected to eliminate an electron from W3+ is more prominent than that expected to eliminate an electron from any of the past particles.

Subsequently, choice D, W3+ (g) → W4+ (g) + e-, requires the most energy for the ionization interaction.
