D. CH3CH2CH2OH (1-butanol)

The intermolecular forces in these compounds can be ranked as follows:

1. A. CH3CH2CH2CH3 (n-butane): This compound consists of nonpolar covalent bonds and experiences only weak London dispersion forces between its molecules.

2. B. CH3COON (ethyl ethanoate): Ethyl ethanoate contains polar covalent bonds, and the intermolecular forces include London dispersion forces as well as dipole-dipole interactions. However, the dipole-dipole interactions are relatively weaker than the next two compounds.

3. C. CH3CH2OCH3 (dimethyl ether): Dimethyl ether has polar covalent bonds, leading to London dispersion forces and dipole-dipole interactions. The oxygen atom creates a stronger dipole moment than in ethyl ethanoate, resulting in slightly stronger intermolecular forces.

4. D. CH3CH2CH2OH (1-butanol): 1-butanol contains polar covalent bonds and experiences London dispersion forces, dipole-dipole interactions, and hydrogen bonding. Hydrogen bonding is the strongest intermolecular force among the four compounds, as the hydrogen atoms are directly bonded to the highly electronegative oxygen atom.

Answer:

(9,5) and (2,1)

Explanation:

Answer: m = 95.7 g

Explanation:

Use the equation q = m x Cs x delta T

Step 1: Identify what was provided in the problem.

q = 2000 J

m = ? (this is what we need to find)

Cs = 4.18 J/g °C

delta = 5°C

Step 2: Place known values into the equation.

q = m x Cs x delta T

2000 J = m x (4.18 J/g °C) x 5°C

Step 3: Isolate m by multiplying both sides of the equation by (4.18 J/g °C) x 5°C.

2000 J/(4.18 J/g °C) x 5°C = m

Step 4: Solve for m.

2000 J/(4.18 J/g °C) x 5°C = m

Note that J and °C units cancel and you are left with g only.

m = 95.7 g

To find the difference in pH, we can subtract pH1 from pH2:pH2 - pH1 = -log(3)Using a calculator, we can evaluate the right side of the equation:-log(3) ≈ 0.477Therefore, the pH increases by about 0.477 units when the concentration of positive hydrogen ions is decreased by two thirds.

When the concentration of positive hydrogen ions is decreased by two thirds, the pH increases by about 0.477 units. This can be calculated using the formula:

pH

= -log[H+],

where [H+] represents the concentration of positive hydrogen ions.Using this formula, we can find the initial pH:

pH1

= -log[H+1]

where [H+1] is the initial concentration of positive hydrogen ions. Let's say the initial concentration is x. Then:

pH1

= -log[x]

Now, if the concentration is decreased by two thirds, the new concentration is (1/3)x. Using this value, we can find the new pH:

pH2

= -log[(1/3)x]

= -log(x) - log(3)

Using the formula for pH1, we can substitute -log(x) for pH1:

pH2

= pH1 - log(3).

To find the difference in pH, we can subtract pH1 from pH2:

pH2 - pH1

= -log(3)

Using a calculator, we can evaluate the right side of the equation:

-log(3) ≈ 0.477

Therefore, the pH increases by about 0.477 units when the concentration of positive hydrogen ions is decreased by two thirds.

The stable isotopes of oxygen (O) in the hard skeletons of corals are an important paleothermometer.

Isotopes of an element have the same number of protons but differ in the number of neutrons. In the case of oxygen, the most abundant isotope is oxygen-16 (16O), which has 8 protons and 8 neutrons. However, there are also two less common isotopes: oxygen-17 (17O) with 8 protons and 9 neutrons, and oxygen-18 (18O) with 8 protons and 10 neutrons. The ratio of oxygen-18 to oxygen-16 in the skeletal structures of corals can provide valuable information about past ocean temperatures. This is because the incorporation of oxygen isotopes into the coral skeleton is influenced by the temperature of the surrounding seawater. When the seawater is warmer, corals tend to incorporate more oxygen-18 isotopes into their skeletons. Conversely, during colder periods, they incorporate more oxygen-16 isotopes. By analyzing the ratio of oxygen-18 to oxygen-16 in fossilized coral skeletons, scientists can estimate the temperature of the ocean at the time the coral was alive.

The bonds that hold tRNA molecules in the correct three-dimensional shape are hydrogen bonds.

Hydrogen bonding is defined as a special category of attractive intermolecular forces generated from the dipole-dipole interaction between a hydrogen atom attached to a very strong electronegative atom and another strong electronegative atom.

For example, In water molecules, an H-atom is bound together by an electronegative  O-atom. Hydrogen bonding in water molecules is due to the dipole-dipole interaction between the hydrogen atom of a water molecule and the oxygen atom of another water molecule.

The strength of hydrogen bonding is much more compared to dispersion force and dipole-dipole forces.

Therefore, intermolecular hydrogen bonding between bases of the tRNA molecules is in the correct three-dimensional shape.

At STP, 68.47 grams of water vapour occupy a volume of 22.4 litres.

At STP, the temperature is 273 K (0 °C) and the pressure is 1 atm. According to the Ideal Gas Law, PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature in Kelvin.

To determine the volume of 68.47 grams of water vapor at STP, we need to first convert the mass of water vapor into moles. The molar mass of water is 18.01528 g/mol. Therefore, the number of moles of water vapor is:

moles = mass / molar mass = 68.47 g / 18.01528 g/mol = 3.8001 mol

At STP, one mole of any gas occupies a volume of 22.4 liters. Therefore, the volume of 3.8001 moles of water vapor is:

V = n x 22.4 L/mol = 3.8001 mol x 22.4 L/mol = 84.93 L

Explanation:

_________________________

Using a technique called "dimensional analysis" ; as follows:

________________________

→  " \(\frac{2.34 mol Al}{1} * \frac{6.022*10^{23}atoms Al}{1 mol Al} = ?\)  

________________________

The units "mol Al" ["moles of aluminum"] cancel out; and we have:

________________________

→  "\([(2.34) * (6.022 * 10^{23})] = ?\) atoms of Al [aluminum].

________________________

Note that by definition: 1 (one) "mole" (abbreviated "mol") of anything consists of " \(6.022*10^{23}\) " units " of that particular thing.

 This number:  6.022*10^{23} —is known as:  "Avogadro's number".

________________________

→  [ 2.34 * 6.022 * 10^23] ;

     = 1.409148 * 10^24 ;

                → Round to 3 (Three) significant figures;

                →  since: "2.34" has 3 (Three) significant figures;

                  →  to get: " \(1.41 *10^{24}\)  atoms of aluminum (Al).
