Answer:

They use the pH scale

Explanation:

The strong acid and strong base has high rate constant of dissociation. Weak acid and base are the one whose rate constant for the dissociation is low, they do not dissociate readily in water. Scientist use pH scale to classify substances that are either an acid or a base.

Acid is a solution which releases H⁺ hydrogen ion when dissolved in water. Base are the solution which releases hydroxide ion OH⁻ ion when dissolved in water. . At room temperature pH scale is between 0 to 14. pH of neutral solution is 7.

The pH of acid is between 0-7 on pH scale. acid turns blue litmus paper to red. Acids have sour taste and corrosive nature. Mathematically the concentration of hydrogen ion can be calculated using this formula

Mathematically,

pH=-log[H⁺]

Therefore, scientist use pH scale to classify substances that are either an acid or a base.

Potash is commonly measured in pounds or kilograms, so you may need to convert the units accordingly. Additionally, it's always recommended to consult with a professional or refer to specific guidelines for accurate recommendations

To determine the amount of Potash needed to purchase for 11 acres with a recommendation of \(3 K2O/acre\), you can follow these steps:
1. Calculate the total amount of Potash needed for 11 acres:
 \(3 K2O/acre * 11 acres = 33 K2O\)
2. Convert K2O to Potash (K2O is the chemical formula for Potash):
\(33 K2O * (1 Potash / 1 K2O) = 33 Potash\)

Therefore, you would need to purchase 33 units of Potash for 11 acres with a recommendation of\(3 K2O/acre\).
It's important to note that the specific unit of measurement for Potash was not provided in the question

Answer:

Why are small quantities of chlorofluorocarbons so harmful to the ozone layer?  Free oxygen atoms can replace the chlorine in chlorine monoxide, releasing a free atom of chlorine which can then recombine with an oxygen atom in ozone, destroying more ozone.

Explanation:

The statement for small quantities of chlorofluorocarbons so harmful to the ozone layer is "Free oxygen atoms can replace the chlorine in chlorine monoxide, releasing a free atom of chlorine which can then recombine with an oxygen atom in ozone, destroying more ozone."

The ozone layer is a thin layer of air in the Earth's atmosphere that absorbs nearly all of the sun's damaging UV radiation.

CFCs (chlorofluorocarbons) are harmless and nonflammable compounds made up of carbon, chlorine, and fluorine atoms.

The earth's protective ozone layer is destroyed by chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), and halons, which shield the earth from damaging ultraviolet (UV-B) rays released by the sun. CFCs and HCFCs also warm the earth's lower atmosphere, causing global climate change.

When some substances are exposed to high UV radiation in the stratosphere, they emit chlorine or bromine. Ozone-depleting chemicals are compounds that contribute to ozone depletion (ODS). Chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), carbon tetrachloride, and methyl chloroform are examples of ODS that produce chlorine. Halons and methyl bromide are two ODS that emit bromine.

Because there isn't much ozone in the atmosphere, what little there is is critical for protecting the Earth's surface from excessive UV light from the Sun. It turns out that it reacts with chlorine, which means that chlorine effectively eliminates ozone.

When the chlorine in CFCs combines with ultraviolet light, it releases chlorine, which then reacts with ozone, reducing the protection humans get from ultraviolet light, allowing more CFCs to release chlorine, and so on. Multiple ozone molecules will interact with one free chlorine atom, which is free because UV light has hit the CFC molecule. As a result, the damage it can cause is likely to be significantly more than you might imagine.

Hence the correct option is c.

Answer:

6 m/s²

Explanation:

Given, Initial velocity (u) = 20m/s

Final velocity (v) = 50m/s

The bond order for a second-period diatomic particle containing five electrons in antibonding molecular orbitals and eight electrons in bonding molecular orbitals is 1.5

Bond order is defined as the number of electrons in bonding molecular orbitals minus the number of electrons in antibonding molecular orbitals divided by two. As a result, we may determine the bond order of this diatomic particle by the formula: Bond order = (number of bonding electrons - number of antibonding electrons) / 2

Bond order = (8 - 5) / 2

Bond order = 1.5.

This diatomic molecule, according to the bond order, is a stable molecule since the bond order is greater than 1, indicating that it is a double bond. The molecule has an overall bond strength that is greater than a single bond, but not as strong as a triple bond. So therefore he bond order for a second-period diatomic particle containing five electrons in antibonding molecular orbitals and eight electrons in bonding molecular orbitals is 1.5

We have an alkene due to the presence of a double bond in the chain. Alkenes are named by placing the ending -ene at the end of the word.

Now, to name the initial part we must count the carbons present in the molecule. We start by counting from the side closest to the double bond so that the carbon that has the double bond has the lowest possible value. Let's see how the numbering would be:

We see that the molecule has 5 carbons, so it will start with pent-, and the double bond is located at carbon number two. So the name of the molecule will be: 2-pentene
