Show your reasoning in describing what would be the effect on the calculated equilibrium constant for each of the following mistakes.
1. Your buret was not rinsed with NaNCS solution before use and still contained traces of distilled water.
2. The spectrophotometer was set well-past infinite absorbance upon calibration with the sample holder empty.

Answers

Answer:

The readings of equilibrium constant is incorrect.

Explanation:

There is a mistake in the value of equilibrium constant if the burette contains traces of distilled water because the water will be present in the solution from which equilibrium constant is calculated. The spectrophotometer did not give the correct reading because its calibration is incorrect. If we want to gain correct readings from the spectrophotometer, we must have to calibrate the instrument correctly.

Incorrect value of equilibrium constant is obtained.

What is equilibrium constant?

Equilibrium constant of any reaction tells about the relative ration of the concentration of products to the reactants.

Value of equilibrium constant can be calculated in the aqueous medium where concentration of water also present. If we don't rinse the burette with the reaction solution then the already present traces of water affect the concentration of water during the calculation of equilibrium constant.

As the absorbance of any solution is also directly proportional to the concentration, so if the spectrometer is not calibrated accurately then incorrect value of absorbance also affects the value of equilibrium constant.

Hence, we get incorrect value of equilibrium constant for each of the given mistakes.

The ratio of the measured molar volume of a real gas to the measured molar volume if the gas
were to behave ideally is known as​

Answers

Answer: compressibility

Explanation:

The ratio of the measured molar volume of a real gas to the measured molar volume  of an ideal gas is known as​ compressibility.

Compressibility is defined by the symbol Z and is calculated by the formula :

[tex]Z=\frac{PV}{nRT}[/tex]

For a gas with ideal behavior, molar volume of an ideal gas is equal to the molar volume of a real gas so Z= 1.

Calculate the Rf value of compounds X and Y based on information (X travels 0.5.0 cm, Y travels 1.0 cm from the origin line; the solvent front is 3.0 cm). Comment on the polarity and separation of X and Y on the TLC plate.

Answers

Answer:

Retention factor or [tex]R_f[/tex] value is defined as the ratio of distance traveled by the unknown to the distance traveled by the solvent front.

[tex]R_f=\frac{\text{ distance by unknown}}{\text {distance by solvent}}[/tex]

Putting in the values we get:

[tex]R_f_{X}=\frac{0.50cm}{3.0cm}=0.16[/tex]

[tex]R_f_{Y}=\frac{1.0cm}{3.0cm}=0.33[/tex]

As the [tex]R_f[/tex] value of Y is more than X , it follows that Y compound will be retained less strongly than the compound X. Thus Y is more polar than X.

l need introduction about vitamin please​

Answers

Vitamins are organic compounds that are traditionally assigned to two groups fat-soluble(hydrophobic) or water-soluble (hydrophilic). This classification determines where they act in the body. Water-soluble vitamins act in the cytosol of cells or in extracellular fluids such as blood; fat-soluble vitamins are largely responsible for protecting cell membranes from free radical damage. The body can synthesize some vitamins, but others must be obtained from the diet.

Answer:

A vitamin is an organic molecule (or a set of molecules closely related chemically, i.e. vitamers) that is an essential micronutrient which an organism needs in small quantities for the proper functioning of its metabolism. Essential nutrients cannot be synthesized in the organism, either at all or not in sufficient quantities, and therefore must be obtained through the diet. Vitamin C

What substance is oxidized in the following reaction? 4HCl + MnO2 → Cl2 + 2H2O + MnCl2

Answers

Answer:

Cl⁻ was oxidized.

Explanation:

4HCl + MnO₂ → Cl₂ + 2H₂O + MnCl₂

Oxidation can be defined as the process in which the oxidation number of a substance increases.

On the left side of the equation, Cl has a charge of -1 (in HCl); while on the right side of the equation Cl has a charge of 0 in Cl₂.

Thus, Cl⁻ was oxidized.

A solution has a [OH-] of 1.43x10-9. What is the pH of this solution?
a. 5.2
b. 8.8
C. 9.1
d. 4.9

Answers

Answer:

a. 5.2

Explanation:

pOH = -log(1.43 x 10^-9) = 8.845

pH = 14 - pOH = 14 - 8.845 = 5.155 ≈ 5.2

Calculate the pH of a solution formed by mixing 550.0 mL of 0.30 M HClO with 275.0 mL of 0.20 M CsClO. The Ka for HClO is 2.9 × 10-8.

Answers

Answer:

pH = 7.08

Explanation:

We can solve this problem using Henderson-Hasselbach's equation:

pH = pKa + log[tex]\frac{[ClO^-]}{[HClO]}[/tex]

With the given concentrations and volumes, we can calculate the new values for [ClO⁻] and [HClO] when the solutions are mixed:

Total volume = 550.0 mL + 275.0 mL = 825.0 mL[HClO] = 550 mL * 0.30 M / 825 mL = 0.20 M[ClO⁻] = 275 mL * 0.20 M / 825 mL = 0.07 M

Now we calculate pKa:

pKa = -log(Ka) = 7.54

Finally we calculate the pH:

pH = 7.54 + log[tex]\frac{0.07}{0.2}[/tex] = 7.08

I can easily work out the molar mass of Ca3PO4 - but I do not see any reason to do this.

There is no such compound

If you want the molar mass of tricalcium phosphate , then the correct formula is Ca3(PO4)2 .

For purposes of calculating the molar mass it is easier to write: Ca3P2O8

Ca = 40.078g/mol *3 = 120.234g

P = 30.974g/mol *2 = 61.948g

O = 15.999g/mol *8 = 127.992g

Total = 310.174g/mol

Mass of 4.5 mol = 310.174g/mol *4.5mol = 1395.783g

g An oxidized silicon (111) wafer has an initial field oxide thickness of d0. Wet oxidation at 950 °C is then used to grow a thin film gate of 500 nm in 50 minutes. What is the original field oxide thickness d0 (in nm)?

Answers

Answer:

Explanation:

From the information given:

oxidation of oxidized solution takes place at 950° C

For wet oxidation:

The linear and parabolic coefficient can be computed as:

[tex]\dfrac{B}{B/A} = D_o \ exp \Big [\dfrac{-\varepsilon a}{k_BT} \Big][/tex]

Using [tex]D_o[/tex] and [tex]E_a[/tex] values obtained from the graph:

Thus;

[tex]\dfrac{B}{A} = 1.63 \times 10^8 exp \Big [ \dfrac{-2.05}{8.617 \times 10^{_-5}\times 1173}\Big] \\ \\ = 0.2535 \ \ \mu m/hr[/tex]

[tex]B= 386 \ exp \Big [-\dfrac{0.78}{8.617 \times 10^{-3} \times 1173} \Big] \\ \\ = 0.1719 \ \mu m^2/hr[/tex]

So, the initial time required to grow oxidation is expressed as:

[tex]t_{ox} = \dfrac{x}{B/A}+ \dfrac{x^2}{B} - t_o (initial)[/tex]

[tex]where; \\ \\ t_{ox} = 2 \ hrs;\\ \\ x = 0.5 \\ \\ B/A = 0.2535 \\ \\ B = 0.1719[/tex]

[tex]2= \dfrac{0.5}{0.2535}+ \dfrac{0.5^2}{0.1719} - t_o (initial)[/tex]

[tex]2 = 3.4267 - t_o (initial) \\ \\ t_o(initial) = 3.4267 - 2 \\ \\ t_o(initial) = 1.4267 \ hr[/tex]

NOW;

[tex]1.4267 = \dfrac{d_o}{0.2535} + \dfrac{d_o^2}{0.1719} \\ \\ 1.4267 = 3.9448 \ d_o + 5.8173 \ d_o^2 \\ \\ d_o^2 + 0.6781 \ d_o = 0.2453[/tex]

[tex]d_o = \dfrac{-b \pm \sqrt{b^2-4ac}}{2a}[/tex]

[tex]d_o = \dfrac{-(0.6781) \pm \sqrt{(0.6781)^2-4(1)(-0.245)}}{2(10)}[/tex]

[tex]d_o = \dfrac{-(0.6781) \pm \sqrt{0.45981961+0.98}}{20}[/tex]

[tex]d_o = \dfrac{-(0.6781) \pm \sqrt{1.43981961}}{20}[/tex]

[tex]d_o = \dfrac{-(0.6781) + \sqrt{1.43981961}}{20} \ OR \ \dfrac{-(0.6781) - \sqrt{1.43981961}}{20}[/tex]

[tex]d_o =0.02609 \ OR \ -0.0939[/tex]

Thus; since we will consider the positive sign, the initial thickness [tex]d_o[/tex] is ;

Four students are gathering information on elements to determine their identity.
Student 1 counts both neutrons and electrons.

Student 3 counts the number of valence electrons.
Student 4 counts the number of protons.
Which of the following students will correctly identify the element based on their
data?

Answers

Answer:

Student 4

Explanation:

In the structure of the atom of an element, there are protons, electrons and neutrons. The number of protons in the atom of such element determines the atomic number of the element. For example, if Calcium contains 20 protons, the atomic no of Calcium will be 20. Since this is so, it means that the identity of an element on the periodic table can be known using the number of protons/atomic no.

According to this question, four students are gathering information on elements to determine their identity. Based on the explanation above, it takes only the number of protons = atomic no. of the element to identify it. Hence, student 4, who counts the number of protons will correctly identify the element using his/her data.
