How many molecules of water are used to completely hydrolyze a polymer that is 11 monomers long?.

Answers

Answer 1

The number of molecules of water required to completely hydrolyze a polymer that is 11 monomers long is 10. Hydrolysis is a chemical reaction in which water is used to break down molecules.

In the process of breaking down polymers, this reaction is used. When hydrolysis occurs, a water molecule is split into a hydrogen ion (H+) and a hydroxide ion (OH-) and these ions are used to break apart the polymer's chemical bonds. This process is repeated until the polymer is broken down into its constituent monomers.

In the process of hydrolysis, one molecule of water is needed to break the bond between each pair of adjacent monomers in the polymer. In other words, one molecule of water is required to break each bond. The number of bonds between the monomers in the polymer is one less than the number of monomers in the polymer. The hydrolysis of a polymer that is 11 monomers long would require 10 molecules of water to break all of the bonds.

Magnesium has a higher melting point than sodium. Calcium is used for the crucible because it has a higher melting point than sodium.

The melting and boiling points of metals increase across the period. Magnesium has a higher melting point because it contributes one additional electron per atom than sodium in the electron sea.

The crucible that will be used for melting sodium must have a higher melting point than sodium. Therefore, a calcium crucible should be used.

The metal that has the lowest melting point must be the metal that has the lowest density and therefor is easiest to bend. That is metal B.

A very important property of metals is ductility. It allows a metal to be drawn into sheets without breaking. Hence, the property of metals that explains the fact that the towers of the bridge does not break into pieces like glass but rather bends is called ductility.

Answers

The firm should order 65 units this week to meet the order-up-to level of 80 units and cover the backordered units.

To determine how many units a firm should order this week given an order-up-to level of 80 units, no on-hand units, 20 on-order units, and 5 backordered units, follow these steps:

1. Calculate the total units needed: Order-up-to level (80) minus on-hand units (0) equals 80 units needed.
2. Subtract the on-order units from the total units needed: 80 units needed minus 20 on-order units equals 60 units still required.
3. Account for the backordered units: 60 units still required plus 5 backordered units equals 65 units.

The equilibrium constant of this reaction is 1.80×10-5

Given data,

pH of solution = 2.873

Number of moles of acetic acid (m) = 0.05 moles

Volume of water (V) =  500 mL = 0.5L

So, concentration (C) = m/V in lit = 0.05/0.5 = 0.1 M

Equilibrium constant ( K ) = \([CH_{3} COO-]\)×\([H+_{} ]\)/\([CH_{3} COOH]\)

Since, acetic acid is weak acid,

So, Equilibrium constant ( K ) = \([H+]^{2}\)/\([CH_{3} COOH]\)   ....(i)

As the pH = 2.873, the \([H+_{} ]\) is antilog of -2.873 or 1.34×10-3 M.

A 3.5L flexible container holds a gas at 250K. What will the new volume be if the temperature is increased to 400K?

Answers

Answer: 5.6L

Explanation:

Just did it on an assignment

A 3.5L flexible container holds a gas at 250K. The new volume will be 5.6 L, if the temperature is increased to 400K.

What is Charles Law ?

Charles law is an ideal gas law which states that at a constant pressure volume of a gas is directly proportional to the absolute temperature.

It is expressed as

\(\frac{V_1}{T_1} = \frac{V_2}{T_2}\)

where,

V₁ = initial volume

T₁ = initial temperature

V₂ = final temperature

T₂ = final temperature

Now put the values in above formula, we get

\(\frac{V_1}{T_1} = \frac{V_2}{T_2}\)

\(\frac{3.5\ L}{250\ K} = \frac{V_2}{400\ K}\)

\(V_{2} = \frac{3.5\ L \times 400\ K}{250\ K}\)

\(V_{2} = \frac{1400}{250}\)

V₂ = 5.6 L

Thus, from the above conclusion we can say that A 3.5L flexible container holds a gas at 250K. The new volume will be 5.6 L, if the temperature is increased to 400K.

Atoms are actually larger than electrons, which are subatomic particles that orbit the nucleus of an atom. The nucleus of an atom contains protons and neutrons, while electrons exist in energy levels surrounding the nucleus. Atoms can combine with other atoms to form compounds, which are made up of two or more different types of atoms bonded together.

Answers

The natural abundance of each isotope can be calculated using the average atomic mass and the isotopic masses of 6li and 7li.  The natural abundance of 7li is much higher than 6li in lithium.

The atomic mass of 6li is 6.01512 amu and the atomic mass of 7li is 7.01600 amu. To find the natural abundance of each isotope, we can use the following formula:
(6li abundance x 6.01512 amu) + (7li abundance x 7.01600 amu) = 6.941 amu
Solving for the abundances, we get:
6li abundance = 0.0759 or 7.59%
7li abundance = 0.9241 or 92.41%
Therefore, the natural abundance of 7li is much higher than that of 6li in lithium.

In conclusion, the natural abundance of each isotope of lithium can be determined using the average atomic mass and isotopic masses. The natural abundance of 7li is much higher than 6li in lithium.

Answers

at the given temperature, HI will decompose into H2 and I2.

Given that the following reaction has an equilibrium constant value of

K = 46 at 783K: H2 (g) + l2 (g) = HI (g).

Initial pressures were given to be 55kPa for both hydrogen and iodine and 78kPa for hydrogen iodide which is at equilibrium. In this problem, Qp is the reaction quotient for pressures at the given instant. Qp has the same expression as Kp, but with initial pressures instead of equilibrium pressures.

Qp = p(HI) / [p(H2) . p(I2)] = 78 / [55 . 55] = 0.0241

K is the equilibrium constant and Q is the reaction quotient.Q is less than K. This implies that the reaction quotient will increase to match the equilibrium constant.

As a result, the reaction will shift forward to produce more HI. Thus, at the given temperature, HI will decompose into H2 and I2.

what is the importance of polar covalent and hydrogen bonds in the structure of water?​

Answers

Answer:

Water is a remarkable substance, and its unique properties are largely due to the presence of polar covalent bonds and hydrogen bonds in its structure. These characteristics play a crucial role in the physical and chemical properties of water, making it essential for life as we know it.

Explanation:

The polar covalent bonds in water arise from the unequal sharing of electrons between oxygen and hydrogen atoms. This results in the oxygen atom having a partial negative charge (δ-) and the hydrogen atoms having partial positive charges (δ+). These charges create polarity within the water molecule, leading to the formation of hydrogen bonds.

Hydrogen bonds occur when the partially positive hydrogen atom of one water molecule is attracted to the partially negative oxygen atom of another water molecule. These hydrogen bonds are relatively weak individually, but when present in large numbers, they contribute to the cohesion, surface tension, and high boiling point of water.

The importance of these bonds is manifold. The cohesion between water molecules due to hydrogen bonding enables water to form droplets, have a high surface tension, and flow freely, facilitating transport within organisms and in the environment. Additionally, hydrogen bonding leads to the high specific heat capacity and heat of vaporization of water, making it an effective regulator of temperature in living organisms and ensuring stable environmental conditions.

Furthermore, hydrogen bonds play a crucial role in the unique properties of water as a solvent. The polar nature of water allows it to dissolve a wide range of substances, including ionic compounds and polar molecules, facilitating various biological processes such as nutrient transport and chemical reactions in cells.

In the first step, a base abstracts a proton from the carbonyl compound, resulting in the formation of a negatively charged species called the enolate ion. This deprotonation step increases the nucleophilicity of the carbonyl carbon.

In the second step, the enolate ion, acting as a nucleophile, attacks the halogen atom, which leads to the formation of a carbon-halogen bond. This step is an example of nucleophilic substitution.

Depending on the specific carbonyl compound and reaction conditions, a rearrangement step may occur if there is a possibility for a more stable carbocation intermediate to form. Rearrangement can lead to the formation of different constitutional isomers halogenation.

Finally, after the halogen has been attached to the carbonyl compound, the reaction is complete, and the resulting product is the halogenated carbonyl compound.

It is important to note that the exact mechanism and conditions may vary depending on the specific carbonyl compound and halogen used in the reaction.

Cordell bought new tires for his bicycle. As he rode his bike on the hot street, the temperature of the air in the tires increased. If the volume of the air stayed the same, what happened to the pressure inside the tires?
A. It decreased. B. It increased. C. It stayed the same. D. It was inversely proportional to the temperature

Answers

Answer: The answer is B. The pressure inside the tires increased.

Explanation:

The relationship between the pressure, volume, and temperature of a gas is described by the ideal gas law, which is usually written as:

\($$PV = nRT$$\)

where:

- \(\(P\)\) is the pressure,

- \(\(V\)\) is the volume,

- \(\(n\)\) is the number of moles of gas,

- \(\(R\)\) is the ideal gas constant, and

- \(\(T\)\) is the temperature (in Kelvin).

In this case, the volume \(\(V\)\) and the number of moles \(\(n\)\) of air in the tires stay the same. The temperature \(\(T\)\) is increasing. Therefore, for the equation to remain balanced, the pressure \(\(P\)\) must also increase.

So, the answer is B. The pressure inside the tires increased.

Compare the compressibility of solids and liquids. Support your answer by describing the arrangement of particles in solids and liquids.(Does,t need to be very long or detailed)

Answers

Liquids are more compressible than solids.

In liquids there is space between the molecules, not a lot, but there is enough space to offer some compressibility. Solids are arranged in regular patterns and their molecules are almost fixed close together.

How do you prepare 500ml of 1.77M H2SO4 solution from an 18.0M H2SO4 Stock solution

Answers

Answer:

Take 49.2-ml of 18.0 M H2SO4 stock solution and pour it into a 500-ml volumetric flask. Fill to the 500-ml line with distilled water to make 1.77M H2SO4 solution.

Explanation:

use the formula M1V1=M2V2

volume must be in liters(L)

\((1.77)(500 \times {10}^{ - 3} ) = (18)v2 \\ 0.885 = 18v2 \\ v2 = \frac{0.885}{18} \\ v2 = 0.04916\)

0.04916L × 1000 = 49.16 ml = 49.2 ml

ionizing radiation is more effective than nonionizing radiation in killing microbes.

Answers

True; "ionizing radiation is more effective than nonionizing radiation in killing microbes".

What is ionizing radiation?

Ionizing radiation, including nuclear radiation, consists of subatomic particles or electromagnetic waves that have sufficient energy to ionize atoms or molecules by detaching electrons from them.

Non-ionizing radiation refers to any type of electromagnetic radiation that does not carry enough energy per quantum to ionize atoms or molecules—that is, to completely remove an electron from an atom or molecule.

Thus, based on the definition above, we can conclude that the statement is true; "ionizing radiation is more effective than nonionizing radiation in killing microbes".

what is a solution of a homogeneous mixture of one or more solutes dissolved in a solvent

Answers

A homogenous mixture of one or more solutes that have been dissolved in a solvent is known as a solution. Keep in mind that the substance that is present in the highest amount is the solvent.

In a homogenous mixture, what is the solution?

Solutions are homogenous solutions made up of at least two different compounds, referred to as the solute and solvent. The thing that dissolves is called the solute. The emulsifying agent is the solvent. It is impossible to tell the difference between the solvent and the solute when looking at a solution. A solution is a specific kind of homogenous mixture made up of two or more different substances. A mixed type with a homogeneous composition is called a homogeneous mixture. This indicates that it is difficult to separate the chemicals from one another.

The composition and features of homogeneous solutions are constant. Several examples include a cup of coffee, fragrance, cough syrup, a saltwater or sugar water solution, etc.
