Answer 1

true,a multifaceted synthetic route to functional polyacrylates by trans-esterification of poly(pentafluorophenyl acrylates).

polyacrylate, any of a class of synthetic resins derived from the polymerization of acrylic esters. Polyacrylates are used primarily in paints and other surface coatings, adhesives, and textiles because they can be formed into plastic materials with notable clarity and flexibility using certain methods. They are strong and flexible, allowing for the creation of solid products with a supple texture. It is a large compound that cannot pass through the skin's barrier and has been shown to be safe for cosmetic use. Polyacrylate, also known as Acrylate polymers, is a type of polymer that is commonly referred to as a plastic. Transesterification is the process of exchanging the organic group R′′ of an ester with the organic group R' of an alcohol in organic chemistry. The addition of an acid or base catalyst frequently catalyses these reactions. Other enzymes, particularly lipases, can also be used to carry out the reaction.

pOH of the 0.001M NaOH solution is​

Answers

The pOH of the 0.001 M NaOH solution is approximately 3.

To determine the pOH of a solution, we need to know the concentration of hydroxide ions (OH-) in the solution.

In the case of a 0.001 M NaOH solution, we can assume that all of the NaOH dissociates completely in water to form Na+ and OH- ions. Therefore, the concentration of hydroxide ions in the solution is also 0.001 M.

The pOH is calculated using the equation:

pOH = -log[OH-]

Substituting the concentration of hydroxide ions, we have:

pOH = -log(0.001)

Using a calculator, we can evaluate the logarithm:

pOH ≈ 3

Therefore, the pOH of the 0.001 M NaOH solution is approximately 3.

the sample?
Express your answer to 3 significant figures.

Answers

Answer:

Hope this helps ;) don't forget to rate this answer !

Explanation:

To find the number of moles of Cr(NO3)3 in the sample, we need to determine the number of moles of each element present in the compound.

The chemical formula for Cr(NO3)3 tells us that for every 1 mole of Cr(NO3)3, there is 1 mole of chromium (Cr), 3 moles of nitrogen (N), and 9 moles of oxygen (O).

We are given that the sample contains 8.36 moles of oxygen. Since the ratio of oxygen to Cr(NO3)3 is 9:1, the number of moles of Cr(NO3)3 in the sample is 8.36 moles O / 9 moles O/mole Cr(NO3)3 = 0.93 moles Cr(NO3)3.

Rounded to 3 significant figures, the answer is 0.93 moles Cr(NO3)3.

Harnessing Human Energy Chapter 3 Lesson 3.3
Writing an Argument for the School Principal

The argument for Harnessing Human Energy  for the School Principal is written below

Dear Principal Tom,

Why we need to Harness Human Energy

Human power as we have been taught is the effort or energy created by a human being. It is one that can be said to be pace of work per time. The Muscles act as the main source of power, and body heat can also be used for tasks like warming food, shelters, or other people.

There are lot of reasons why we need to make use of these energy and this is coming form the fact that energy from the environment is transformed by humans into forms that are very beneficial for their activities.

An example to buttress this point is from the first person to understand that running a magnet via a copper wire could create an electric current was an English physicist named Michael Faraday. It was a truly remarkable finding. Magnets and copper wire coils are used in enormous power plants to create almost all of the electricity we use today. Therefore, harnessing human energy can do us more good than harm.

use the curves to determine the partial pressure of oxygen at 50% saturation for hemoglobin and myoglobin.

Answers

Based on the given oxygen-binding curve, partial pressure of oxygen at 50% saturation for hemoglobin is ≈ 28 pO2 and myoglobin ≈ 2 pO2. Myoglobin has a higher affinity for oxygen.

An oxygen-binding curve refers to the curve that illustrated the relationship between fractional saturation versus the concentration of oxygen. Fractional saturation indicates the presence of binding sites that have oxygen and range from zero (all sites are empty) to one (all sites are filled). Myoglobin and hemoglobin have slightly different properties due to their different structures which are commonly described by the oxygen binding curve. Based on the given curve, partial pressure of oxygen at 50% saturation for hemoglobin is ≈ 28 pO2 and myoglobin ≈ 2 pO2.  

Myoglobin demonstrated a regular curve as when the concentration of oxygen is increased, myoglobin becomes saturated very quickly and then levels off, implying that myoglobin has a high affinity for oxygen, binds oxygen strongly and does not release oxygen very easily. Hemoglobin displays a sigmoidal curve, implying that hemoglobin has a lower affinity for oxygen, binds oxygen relatively weakly and releases it more easily than myoglobin.

Note: The question is incomplete. The complete question probably is: The graph below shows the oxygen-binding curves for myoglobin and hemoglobin. Use the curves to estimate the partial pressure of oxygen at 50% saturation for hemoglobin and myoglobin. Can you derive from these values, which protein has a higher affinity for oxygen?

Suppose a different fatty acid molecule were used, with a molecular volume of 4.48 x 10-22 mL/molecule, and a molar mass of 235 g/mol. Use these data and the expected value for Avogadro's number to calculate its density (g/mL) by dimensional analysis. Hint: try starting with 235 g over 1 mole.

Answers

Density (g/mL) can be calculated as mass per volume.

Mass = molar mass (g/mol) * number of moles
Volume = molecular volume (mL/molecule) * Avogadro's number

Mass = 235 g/mol * 1 mole
Volume = 4.48 x 10^-22 mL/molecule * 6.022 x 10^23 molecules/mol

Density (g/mL) = Mass / Volume
Density (g/mL) = 235 g/mol / (4.48 x 10^-22 mL/molecule * 6.022 x 10^23 molecules/mol)

This calculation yields a density of approximately 0.77 g/mL

if this decay has a halflife of 2.60 years what mass of 72.5g sodium-22 will remain after 15.6 years? how many grams?

Answers

The remaining mass is subject to random fluctuations due to the probabilistic nature of radioactive decay. After 15.6 years, only 1.133 grams of the original 72.5 grams of sodium-22 will remain.

Sodium-22 undergoes radioactive decay with a half-life of 2.60 years. This means that after 2.60 years, half of the original mass of sodium-22 will decay, and after another 2.60 years, half of the remaining mass will decay, and so on.

To calculate the mass of sodium-22 remaining after 15.6 years, we can use the formula:

mass remaining = initial mass x (1/2)^(t/half-life)

where "t" is the time that has elapsed, "half-life" is the half-life of the radioactive substance, and "initial mass" is the original mass of the substance.

Plugging in the values given in the problem, we get:

mass remaining = 72.5g x (1/2)^(15.6/2.60) = 72.5g x (1/2)^6 = 72.5g x 0.015625 = 1.133g

It's important to note that the formula used here assumes that the decay rate of the substance is constant over time, which may not be the case in reality.

How does the mean free path in a sample of gas vary with temperature in a constant-volume container ?

Answers

Answer:

The mean free path in a sample of gas is the average distance traveled by a gas molecule between successive collisions with other molecules. In a constant-volume container, the mean free path is influenced by temperature.

As temperature increases, the kinetic energy of gas molecules also increases. This leads to higher molecular speeds and more frequent collisions between molecules. Consequently, the average distance traveled by a gas molecule between collisions decreases, resulting in a shorter mean free path.

Therefore, in a constant-volume container, as temperature increases, the mean free path of gas decreases.
