If a buffer has an initial pH of 6.34 and the acid has a Ka of 3.46 × 10-4, what is the ratio of conjugate base to weak acid in the buffer system?

Answers

Answer: The ratio of conjugate base to weak acid in the buffer system is 758 : 1

Explanation:

The dissociation constant for  acid = [tex]K_a=3.46\times 10^{-4}[/tex]

pH = 6.34

First we have to calculate the value of [tex]pK_a[/tex].

The expression used for the calculation of [tex]pK_a[/tex] is,

[tex]pK_a=-\log (K_a)[/tex]

Now put the value of [tex]K_a[/tex] in this expression, we get:

[tex]pK_a=-\log (3.46\times 10^{-4})[/tex]

[tex]pK_a=3.46[/tex]

Now we have to calculate the ratio of conjugate base to weak acid in the buffer system

Using Henderson Hesselbach equation :

[tex]pH=pK_a+\log \frac{[\text {conjugate base}]}{[Acid]}[/tex]

Now put all the given values in this expression, we get:

[tex]6.34=3.46+\log \frac{[\text {conjugate base}]}{[Acid]}[/tex]

[tex]\frac{[\text {conjugate base}]}{[Acid]}=758[/tex]

Therefore, the ratio of conjugate base to weak acid in the buffer system is 758: 1

0.450 moles of K2SO4 are dissolved in 195.0 mL of water. Calculate the molarity of the solution.

Answers

Answer:

2.31M

Explanation:

The following data were obtained from the question:

Mole of K2SO4 = 0.450 mole

Volume of water = 195.0 mL = 195/1000 = 0.195L

Molarity =...?

Molarity is defined as the mole of solute per unit litre of the solution. This can be expressed as:

Molarity = mole /Volume

With the above formula we can calculate the molarity of the K2SO4 solution as follow:

Molarity = mole /Volume

Molarity = 0.450/0.195

Molarity = 2.31M

following balanced equation.
2012(g) + 702(g) + 130 kcal yields 201207(9)

Answers

Answer: 780 kcal are required to produce 12.00 mol of [tex]Cl_2O_7[/tex]

Explanation:

Endothermic reactions are defined as the reactions in which energy of the product is greater than the energy of the reactants. The total energy is absorbed in the form of heat and written along with reactants.

The balanced chemical reaction is:

[tex]2Cl_2(g)+7O_2(g)+130kcal\rightarrow 2Cl_2O_7(g)[/tex]

According to stoichiometry :

2 moles of [tex]Cl_2O_7[/tex] are produced by absorption of energy = 130 kcal

Thus 12.00 moles of [tex]Cl_2O_7[/tex] are produced by absorption of energy = [tex]\frac{130}{2}\times 12.00=780kcal[/tex]

Thus 780 kcal are required to produce 12.00 mol of [tex]Cl_2O_7[/tex]

Suppose the yield of the first step is 71.% and the yield of the second step is 72.%. Calculate the mass of oxygen required to make 7.0 kg of iron.
Be sure your answer has a unit symbol, if needed, and is rounded to 2 significant digits.

Answers

Answer:

5.9 kg  

Explanation:

We must work backwards from the second step to work out the mass of oxygen.

1. Second step

Mᵣ:                                     55.84

            Fe₂O₃ + 3CO  ⟶  2Fe  +  3CO₂

m/kg:                                    7.0

(a) Moles of Fe

[tex]\text{Moles of FeO} = \text{7000 g Fe} \times \dfrac{\text{1 mol Fe}}{\text{55.84 g Fe}} = \text{125 mol Fe}[/tex]

(b) Moles of CO

[tex]\text{Moles of CO} = \text{125 mol Fe} \times \dfrac{\text{3 mol CO}}{\text{2 mol Fe}} = \text{188 mol CO}[/tex]

However, this is the theoretical yield.

The actual yield is 72. %.

We need more CO and Fe₂O₃ to get the theoretical yield of Fe.

(c) Percent yield

[tex]\begin{array}{rcl}\text{Percent yield} &=& \dfrac{\text{ actual yield}}{\text{ theoretical yield}} \times 100 \, \%\\\\ 72. \, \% & = & \dfrac{\text{188 mol}}{\text{actual yield}} \times 100 \,\%\\\\0.72 &= &\dfrac{\text{188 mol}}{\text{actual yield}}\\\\\text{Actual yield} & = & \dfrac{\text{188 mol}}{0.72}\\& = & \textbf{261 mol}\\\\\end{array}[/tex]

We must use 261 mol of CO to get 7.0 kg of Fe.

2. First step

Mᵣ:                32.00

            2C   +  O₂   ⟶  2CO

n/mol:                             261

(a) Moles of O₂

[tex]\text{Moles of O}_{2} = \text{261 mol CO} \times \dfrac{\text{1 mol O}_{2}}{\text{2 mol CO}} = \text{131 mol O}_{2}[/tex]

(b) Mass of O₂

[tex]\text{Mass of O}_{2}= \text{131 mol O }_{2} \times \dfrac{\text{32.00 g O}_{2}}{\text{1 mol O}_{2}} = \text{4180 g O}_{2}[/tex]

However, this is the theoretical yield.

The actual yield is 71. %.

We need more C and O₂ to get the theoretical yield of CO.

(c) Percent yield

[tex]\begin{array}{rcl}71. \, \% & = & \dfrac{\text{188 mol}}{\text{actual yield}} \times 100 \,\%\\\\0.71 &= &\dfrac{\text{4180 g}}{\text{actual yield}}\\\\\text{Actual yield} & = & \dfrac{\text{4180 g}}{0.71}\\\\& = & \text{5900 g}\\& = & \textbf{5.9 kg}\\\end{array}[/tex]

We need 5.9 kg of O₂ to produce 7.0 kg of Fe.

1. What are the trends for atomic size across a period and down a group for the
main group elements?
2. Draw the following Lewis structures:
a) ammonium ion b) sulfur trioxide c) hydrogen cyanide
3. Using formal charge formula (or electronegativity differences), to determine
the following the best structure, OCS, COS or CSO.

Answers

Answer:

Here's what I get  

Explanation:

1. Trends in atomic size

Atomic size tends to decrease from left to right across the Periodic Table.

You are adding one electron at a time. the electrons repel each other, so the size should increase.

You are also adding a proton to the nucleus. The additional attraction should pull the electrons closer to the nucleus.

The nuclear pull wins, so the atoms get smaller from left to right

Atomic size increases from top to bottom of a Group.

You are adding electrons to an extra shell, so the size should increase.

You are also adding protons to the nucleus, so the size should decrease.

The size of the outer shell wins, so the atomic size increases going down a Group.

2. Lewis structures

(a) Ammonium ion

N is the central atom. The N atom has the positive charge.

(b) Sulfur trioxide

S is the central atom, with a double bond to each of the three O atoms.

(c) Hydrogen cyanide

C is the central atom, with a triple bond to the N atom.

3. COS

The best structure is that of O=C=S. It has no formal charges.

The Lewis structures for the other arrangements have formal charges.

The correct answers of this question is given below.

1. The atomic size increases going down a Group.2. (a) Ammonium ion : The N atom has the positive charge.    (b) Sulfur trioxide : Having double bond to each of the three O    atoms.    (c) hydrogen cyanide : Having a triple bond to the N atom.3. COS and it has no formal charges

The temperature of a sample of gas in a steel


tank at 30.0 kPa is increased from -100.0°C to


25.0 °C. What is the final pressure inside the


tank?


A. 5.17 kPa


B. 51.7 kPa


C. 517 kPa


D. 5170 kPa

Answers

Answer:

[tex]P_2=51.7kPa[/tex]

Explanation:

Hello,

In this case, we apply the Gay-Lussac's law which allows us to understand the pressure-temperature behavior via a directly proportional relationship:

[tex]\frac{P_1}{T_1}=\frac{P_2}{T_2}[/tex]

Thus, since we are asked to compute the final pressure we solve for it in the previous formula, considering the temperature in absolute Kelvin units:

[tex]P_2=\frac{P_1T_2}{T_1}=\frac{30.0kPa*(25.0+273)K}{(-100.0+273)K} \\\\P_2=51.7kPa[/tex]

Best regards.

Answer:

B = Pressure = 51.7kPa

Explanation:

P1 = 30kPa

T1 = -100°C = (-100 + 273.15)K = 173.15K

T2 = 25°C = (25 + 273.15)K = 298.15K

P2 = ?

This question involves the use of pressure (p) law which states that the pressure of a fixed mass of gas is directly proportional to its temperature(t) provided that the volume of the gas is kept constant.

Mathematically,

P = kT, k = P / T

P1 / T1 = P2 / T2 = P3 / T3 =.......= Pn / Tn

P1 / T1 = P2 / T2

Solve for P2,

P2 = (P1 × T2) / T1

P2 = (30 × 298.15) / 173.15

P2 = 8944.5 / 173.15

P2 = 51.66kPa

The pressure of the gas is approximately 51.7kPa

Explain the different principles that allow roller coasters to rip and roar around the tracks. In your response, include how energy is transferred back and forth between kinetic and potential.

Answers

Answer:

In the roller coasters the potential energy that is given is the gravitational potential energy, which this energy increases its value as the object moves away from the earth, that is to say, the more height the roller coaster acquires the more gravitational potential energy it will have, and Said train where people usually get on the roller coaster will descend or descend with greater acceleration.

This gravitational potential energy once the mountain begins to descend or descend is converted into kinetic energy

Explanation:

This that we wrote above is considering that the roller coaster does not have curved routes but rectilinear, in the case that it had curved routes, a force would be added in addition to those written that is the centripetal force, it is the same force that appears in the centrifuges or dryers of clothes or the same washing machine. This force, the centripetal force is the force that draws a moving object, in a curvilinear path, towards the center of the curvature.
