O Ethane, because its molecules can fit into the spaces between water molecules more easily than those of propanol can.
O Propanol, because its molecules have a greater mass than the molecules of ethane have.
O Propanol, because its molecules can form hydrogen bonds with water molecules.

Answers

Propanol, because its molecules can form hydrogen bonds with water molecules.

Reason:

Propanol contains a hydroxyl (-OH) group, which can form hydrogen bonds with the partially negative oxygen atoms in water molecules.This interaction increases the solubility of propanol in water.Ethane is a nonpolar hydrocarbon and it does not have any functional groups that can interact with water in this wayHydrogen bonding between propanol and water makes the solution more stable and thus more soluble.Nonpolar compounds like Ethane are not attracted to water molecules and are less likely to dissolve in them.

Therefore, propanol is more soluble in water than Ethane.

What volume (in L) of nitrogen will be produced from the reaction of 6. 8 L of carbon monoxide?


2CO(g)+2NO(g)>N2(g)+2CO2(g)

Answers

The volume of nitrogen produced from the reaction of 6.8 L of carbon monoxide is 3.7 L

In order to determine the volume of nitrogen produced from the reaction of 6.8 L of carbon monoxide, we need to use the balanced equation for the reaction:

2CO(g) + 2NO(g) -> N2(g) + 2CO2(g)

From the equation, we can see that for every 2 moles of CO that react, 1 mole of N2 is produced. The volume of a gas is directly proportional to the number of moles of the gas present.

If the initial volume of CO is 6.8 L, we can assume that the number of moles of CO is

6.8 L / 24.45 L/mol = 0.278 mol.

Therefore, the number of moles of N2 produced would be

0.278 mol CO * (1 mol N2 / 2 mol CO) = 0.139 mol N2.

Finally, using the ideal gas law PV = nRT (where P is pressure, V is volume, n is the number of moles, R is the ideal gas constant, and T is temperature), we can calculate the volume of N2 produced:

V = nRT / P

V = 0.139 mol N2 * (8.314 J/mol*K) * (273 K) / (1 atm) = 3.7 L

So, the volume of nitrogen produced from the reaction of 6.8 L of carbon monoxide is 3.7 L.

The activation energy of a first order reaction is 83. 5kJ/mol. The rate constant is 3. 54x10^-5s^-1 at 45 C. What is the rate constant at 65 C?

Answers

The rate constant at 65 C is k65= 4.8 x 10^-5 s^-1 .Below is the explanation for the answer

To find the rate constant at a different temperature, you can use the Arrhenius equation, which relates the rate constant to the activation energy and the temperature. The equation is:

k = A * e^(-Ea/RT)

where
k is the rate constant,
A is the pre-exponential factor (also known as the frequency factor),
Ea is the activation energy,
R is the universal gas constant,
T is the absolute temperature.

We are given that the activation energy is 83.5 kJ/mol and the rate constant at 45 C is 3.54 x 10^-5 s^-1. To find the rate constant at 65 C, we can substitute these values into the equation and solve for k.

k = A * e^(-Ea/RT)
k = 3.54 x 10^-5 s^-1 * e^(-(83.5 kJ/mol) / (8.314 J/mol*K * (45 + 273.15 K))

However, A is a constant that we don't know. To find the rate constant at 65 C, we can use the fact that the rate constant is proportional to the temperature. Therefore, we can find the ratio of the rate constants at 65 C and 45 C, then multiply it by the rate constant at 45 C to find the rate constant at 65 C.

k65/k45 = (T2/T1)^n
where
k65 is the rate constant at 65 C
k45 is the rate constant at 45 C
T2 is the temperature in Kelvin (65 + 273.15)
T1 is the temperature in Kelvin (45 + 273.15)
n is the order of the reaction, which is 1 in this case

we can find the rate constant at 65 C is:
k65 = k45 (T2/T1)^n
k65 = 3.54 x 10^-5 s^-1 * ( (65 + 273.15) / (45 + 273.15) )^1

Answers

His and Lys are deprotonated but Asp will be protonated.

What is amino acids?

Organic substances that possess both amino and carboxylic acid functional groups are known as amino acids. Although hundreds of amino acids occur in nature, the alpha-amino acids that constitute proteins are by far the most significant. The genetic coding contains only 22 alpha amino acids. Amino acids are chemicals that make proteins when they combine. The building blocks of life are amino acids and proteins. Amino acids are left over after proteins are digested or broken down. To support the body, the human body utilizes amino acids to build proteins: Food should be broken down.

Here,

As the pH is given as 7.4 and pK of His is given as 6.00. There will occur a positive charge on His when it's pH < pK therefore, it is neutral at the given pH.

As the pK value of Lys is 10.53 that is greater than the pH of 7.40. Therefore, charge on Lys is positive.

As the pK value of Asp is 3.65 which is less than the pH value of 7.40. Hence, Asp has a negative charge.

D. Are the following instructions for diluting a 10.0 M solution to a 1.00 M solution correct: "Take 100.0 mL of the 10.0 M solution and add 900.0 mL water"? enter either true or false

Answers

(A) Vol. of solvent is 119.8 ml, (B) Molarity (M) of sol. is 5.00 M, (C) V1 of copper nitrate solution is 187.5 ml, (D) The instruction given is false.  

(A). To calculate the volume (ml) of a 2.25 M potassium hydroxide solution that contains 15.0 g of solute, we can use the formula:

The unit of measurement for molarity (M) is moles of solute per liter of solvent.

Rearranging the formula to solve for liters of solvent:

Molecularity = moles of solute / liters of solvent (M)

We know that the molar mass of potassium hydroxide (KOH) is 56.1 g/mol. To find the moles of solute, we can divide the given mass (15.0 g) by the molar mass of KOH:

15.0 g / 56.1 g/mol = 0.2679 moles

Now we can plug this value into the formula above:

Liters of solvent = 0.2679 moles / 2.25 M

Liters of solvent = 0.1198 L or 119.8 ml (rounded to 3 significant figures)

(B). To calculate the molarity of a solution containing 1.25 moles of glucose in 250. ml of solvent, we can use the formula:

The unit of measurement for molarity (M) is moles of solute per liter of solvent.

Plugging in the given values:

Molarity (M) = 1.25 moles / 0.250 L

Molarity (M) = 5.00 M

(C). To calculate the volume of a 10.00 M copper(II) nitrate solution that must be added to water to prepare 750.0 ml of a 2.500 M solution, we can use the formula:

M1V1 = M2V2

Where M1 and V1 are the concentration and volume of the original solution, and M2 and V2 are the concentration and volume of the final solution.

We know that the final solution has a volume of 750.0 ml and a concentration of 2.500 M, so we can plug in these values for V2 and M2:

M1V1 = 2.500 M x 750.0 ml

Now we can solve for V1 (the original volume) by rearranging the formula:

V1 = M2V2 / M1

V1 = (2.500 M x 750.0 ml) / 10.00 M

V1 = 187.5 ml (rounded to 4 significant figures)

(D). The instructions "Take 100.0 mL of the 10.0 M solution and add 900.0 mL water" are not correct for diluting a 10.0 M solution to a 1.00 M solution.

To achieve this dilution, you would need to take a smaller volume of the 10.0 M solution and add a larger volume of water, because the final volume should be larger than the starting volume.

For example, you could take 10.0 mL of the 10.0 M solution and add 90.0 mL of water, which would give you a final volume of 100.0 mL and a concentration of 1.00 M. The instruction given above is false.

I saw nothing like this, but when we listened very carefully, we couldhear their hum of gentle chattering. Bats use sound to situate themselves;their capacity for echolocation is what guldes them, what elucidates theirsense of space and substance, what locates their prey.
