If the elements W, X, Y, and Z have electronegativity values of 1.0, 2.0, 2.5, and 3.5, respectively, which bond is the least polar

Answers

Answer 1

Answer:

XY bond is the least polar

Explanation:

Given

[tex]W = 1.0[/tex]

[tex]X = 2.0[/tex]

[tex]Y = 2.5[/tex]

[tex]Z = 3.5[/tex]

Required

The least polar bond

First, we calculate the difference in the electronegativities

[tex]WX = X - W[/tex]

[tex]WX = 2.0 - 1.0[/tex]

[tex]WX = 1.0[/tex]

[tex]WY = Y - W[/tex]

[tex]WY =2.5 - 1.0[/tex]

[tex]WY =1.5[/tex]

[tex]WZ =Z-W[/tex]

[tex]WZ =3.5 - 1.0[/tex]

[tex]WZ =2.5[/tex]

[tex]XY = Y -X[/tex]

[tex]XY = 2.5 -2.0[/tex]

[tex]XY = 0.5[/tex]

[tex]XZ = Z -X[/tex]

[tex]XZ = 3.5 -2.0[/tex]

[tex]XZ = 1.5[/tex]

[tex]YZ = Z - Y[/tex]

[tex]YZ = 3.5 - 2.5[/tex]

[tex]YZ = 1.0[/tex]

The least of the above calculations will be the least polar.

Hence, XY is the least polar

The process of diffusion can be described as: Movement of water from the area of high concentration of solute to the area of low concentration of solute. Movement of solute from the area of low concentration of solute to the area of high concentration of solute. Movement of water from the area of low concentration of solute to the area of high concentration of solute. Movement of solute from the area of high concentration of solute to the area of low concentration of solute.

Answers

Answer:

Movement of water from the area of high concentration of solute to the area of low concentration of solute.

Explanation:

Diffusion can be defined as the movement of gas molecules from a region of high concentration to a region of lower concentration until an equilibrium is attained or reached. This mixing of gas molecules in the liquid or gaseous state is due to their kinetic energy of random motion i.e without requiring bulk motion.

This ultimately implies that, diffusion is a phenomenon through which gas molecules in either a gaseous or liquid state spread out in response to a concentration gradient, which is simply the difference in concentration of the gases across a space.

During diffusion, molecules move from areas of high concentration to areas of low concentration. Also, diffusion does not require energy to move molecules.

Hence, the process of diffusion can be described as movement of water from the area of high concentration of solute to the area of low concentration of solute.

A solute can be defined as a substance that is typically dissolved in a liquid solvent such as water, coffee, tea, etc., to produce a solution.

Which statement describes a condensation reaction?

A. monomers break away when one forms a double bond monomers break away with the addition of a water molecule.
B. Two monomers combine when one adds to the double bond of another.
C. Two monomers form a new bond with the loss of a water molecule .

Answers

The statement that describes a CONDENSATION reaction is that two monomers form a new bond with the loss of a water molecule . That is option C.

CONDENSATION REACTION involves the combination of two or more molecules(monomers) of water. In  reaction, a new bond is usually formed.

The characteristics of a condensation reaction includes:

formation of complex molecules (combination of two smaller monomers),water is usually given off as by product it requires a catalyst for a complete reaction to occur

A reaction is called a condensation reaction because a small molecule such as water is released as a byproduct.

A typical example of a condensation reaction is the condensation of amino acids to form dipeptide. The  −OH  from the carboxyl group of one amino acid combines with a hydrogen atom from the amine group of the other amino acid to produce water.

Therefore, the statement that describes a CONDENSATION reaction is that two monomers form a new bond with the loss of a water molecule. That is option C

What is a solution?

A solution is the mixture of solutes that can be more than one in a solvent that has the same composition all over (homogenous). A solution comprises two main elements called a solute and a solvent.

A solute is the part of the solution that has been added to the solvent for desolvation. On the other hand, the solvent is the substance that dissolves the solute in them to make a solution.

The homogenous mixture or the solution can be created by mixing salt and water, sugar and water, mercury in amalgamated zinc, coffee, vinegar, etc.

Therefore, option B. a solution is the addition of the substances that combine physically.

In a synthesis experiment you obtain a sample of product on which you do a melting point determination and find a melting point range of 114 to 125 degrees Celsius. The sample is supposed to be acetylsalicyclic acid. What preliminary conclusion(s) can you reach from this one determination

Answers

Answer:

The melting point determination may need improvement- it may not have been done properly, and make sure it was repeated at least once.

Explanation:

Given that we know the actual melting point of pure acetylsalicyclic acid to be 135°, it follows that the process followed to obtain the melting point range of 114 to 125 degrees Celsius must be inaccurate.

Therefore, we can conclude that, the melting point determination may need improvement. It may not have been done properly, and we must make sure it is repeated at least once.

Answers

Answer:

See explanation

Explanation:

When dealing with the Electromagnetic Spectrum, one should remember the acronym ROYGBIV. This will apply to visible spectrum but the non-visible spectra can de logically deduced from the sequence. That is ...

   R-Red > O-Orange > Y-Yellow > G-Green > B-Blue > I-Indigo > V-Violet

In relation to the three wave properties; wavelength (λ), frequency (ν) & energy (ΔE) ...

Wavelengths => Long λ                                                                       Short λ

Frequency     => Low  ν                                                                       High ν

Energy           => Low  ΔE                                                                    High ΔE  

Note that all 'L's' are on the 'Left'

On Left => Long wavelengths, Low frequency & Low energy; the 'opposites' are on 'the other end of the list'.

Therefore for other wavelengths outside the visible spectrum set up as follows, start with visible spectrum in the middle and insert the invisible spectra of interest.

                          Long λ <= Visible (R.0.Y.G.B.I.V.) => Short λ

 λ (cm):    10¹            10⁻²          10⁻³  (10⁻⁵- 10⁻⁶)    10⁻⁷       10⁻⁹    (10⁻¹¹ - 10⁻¹³)

100cm³ of ethane gas diffuses through a porous plug in 100 seconds.What is the molecular mass of the gas Q if 100cm³ of the gas diffuses through the same plug in 121 secknds under the same condition?(C=12.0,H=1.0)

Answers

Answer:

The molar mass of gas Q is 43.923 g/mol

Explanation:

The given volume of ethane gas that diffuses through a porous plug in 100 seconds = 100 cm³

Therefore;

The rate of diffusion of ethane gas through the porous plug, [tex]v_{ethane}[/tex], is given as follows;

[tex]v_{ethane}[/tex] = (100 cm³/100 s) = 1 cm³/s

The molar mass of ethane, C₂H₆ = 2×12 g/mol + 6×1 g/mol = 30 g/mol

The given volume of gas, Q, that diffuses through a porous plug in 121 seconds = 100 cm³

∴ The rate of diffusion of the gas, Q, [tex]v_Q[/tex] = 100/121 cm³/s

Graham's Law of diffusion states that the rate of diffusion of a gas is inversely proportional to the square root of the molecular mass of the gas

Mathematically, we have;

[tex]\dfrac{v_A}{v_B} =\sqrt{\dfrac{m_B}{m_A} }[/tex]

Where;

[tex]v_A[/tex] = The rate of diffusion of gas A

[tex]v_B[/tex] = The rate of diffusion of gas B

[tex]m_A[/tex] = The molar mass of the gas A

[tex]m_B[/tex] = The molar mass of the gas B

Therefore, for ethane and gas Q, measured under the same condition, we have;

[tex]\dfrac{v_{ethane}}{v_Q} =\sqrt{\dfrac{m_Q}{m_{ethane}} }[/tex]

[tex]\dfrac{1 \ cm^3/s}{\dfrac{100}{121} \ cm^3/s} =\sqrt{\dfrac{m_Q}{30 \ g/mol} }[/tex]

[tex]m_Q = \left ({\dfrac{121}{100} } \right) ^2 \times 30 \ g/mol = 43.923 \ g/mol[/tex]

The molar mass of gas Q, [tex]m_Q[/tex] = 43.923 g/mol.
