The reaction of hypochlorite ion with iodide ion in 1 M aqueous hydroxide solution

OCl- + I- OI- + Cl-

is first order in OCl- and first order in I-.

Complete the rate law for this reaction in the box below.

Use the form k(A)m(B)n..., where '1' is understood for m, n ... (don't enter 1) and concentrations taken to the zero power do not appear.

Rate = k(OCl)-(I)

In an experiment to determine the rate law, the rate constant was determined to be 78.6 M-1s-1. Using this value for the rate constant, the rate of the reaction when

(OCl−)=1.14×10−3 M and (I)]=2.64×10^−3

Answers

Answer 1

Answer: The rate of the reaction is [tex]2.36\times 10^{-4}Ms^{-1}[/tex]

Explanation:

Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.

[tex]OCl^-+I^-\rightarrow OI^-+Cl^-[/tex]

[tex]Rate=k[OCl^-]^m[I^-]^n[/tex]

where m = n = 1

[tex]Rate=78.6M^{-1}s^{-1}\times [1.14\times 10^{-3}M]^1\times [2.64\times 10^{-3}M]^1=2.36\times 10^{-4}Ms^{-1}[/tex]

The rate of the reaction is [tex]2.36\times 10^{-4}Ms^{-1}[/tex]

Methane reacts with chlorine to produce methyl chloride and hydrogen chloride. Once formed, the methyl chloride may undergo further chlorination to form methylene chloride (CH2Cl2), chloroform, and carbon tetrachloride. A methyl chloride production process consists of a reactor, a condenser, a distillation column, and an absorption column. A gas stream containing 80.0 mole% methane and the balance chlorine is fed to the reactor. In the reactor a single-pass chlorine conversion of essentially 100% is attained, the mole ratio of methyl chloride to methylene chloride in the product is 5:1, and negligible amounts of chloroform and carbon tetrachloride are formed. The product stream flows to the condenser. Two streams emerge from the condenser: the liquid condensate, which contains essentially all of the methyl chloride and methylene chloride in the reactor effluent, and a gas containing the methane and hydrogen chloride. The condensate goes to the distillation column in which the two component species are separated. The gas leaving the condenser flows to the absorption column where it contacts an aqueous solution. The solution absorbs essentially all of the HCl and none of the CH4CH4 in the feed. The liquid leaving the absorber is pumped elsewhere in the plant for further processing, and the methane is recycled to join the fresh feed to the process (a mixture of methane and chlorine). The combined stream is the feed to the reactor.

Required:
a. Choose a quantity of the reactor feed as a basis of calculation, draw and label a flowchart, and determine the degrees of freedom for the overall process and each single unit and stream mixing point. Then write in order the equations you would use to calculate the molar flow rate and molar composition of the fresh feed, the rate at which HCl must be removed in the absorber, the methyl chloride production rate, and the molar flow rate of the recycle stream. Do no calculations.
b. Calculate the quantities specified in Part (a), either manually or with an equation-solving program.
c. What molar flow rates and compositions of the fresh feed and the recycle stream are required to achieve a methyl chloride production rate of 1000 kg/h?

A student was directed to convert the mass of a boulder from kg to pounds.
Conversion factor: 1 pound = 454 g
The mass is 22 kg. The student calculated the weight to be 0.048 pounds.
Is this correct? If not, what went wrong?

Answers

Answer:

Incorrect

Explanation:

Given that,

The mass of a boulder, m = 22 kg

We need to find the weight of the student in pounds.

We know that,

1 pound = 454 g

or

1 g = (1/454 pounds)

22 kg = 0.022  grams

So,

0.022 grams = [tex]\dfrac{0.022}{454}\ pounds[/tex]

= 0.000048 pounds

The student says the weight is 0.048 pounds. It means he was incorrect.

How many molecules of CO2 at standard temperature and pressure in 5.4 moles of CO2

Answers

Answer:

3.25×10²⁴ molecules.

Explanation:

From the question given above, the following data were obtained:

Number of mole of CO₂ = 5.4 moles

Number of molecules of CO₂ =?

The number of molecules of CO₂ in 5.4 moles can be obtained as follow:

From Avogadro's hypothesis,

1 mole of CO₂ = 6.02×10²³ molecules

Therefore,

5.4 moles of CO₂ = 5.4 × 6.02×10²³

5.4 moles of CO₂ = 3.25×10²⁴ molecules

Thus, 5.4 moles of CO₂ contains 3.25×10²⁴ molecules.

structure of 2,3-dimethylheptane

Answers

Answer:

Please find the structure of the hydrocarbon in the attachment section and details on how to draw it in the explanation section.

Explanation:

Heptane is a member of the alkane group, which has a general formula of CnH2n+2. If n in heptane is 7, this means that the chemical formula for heptane will be C7H16 i.e.

= C7H2(7) + 2

= C7H14+2

= C7H16

C7H16 is the chemical formula for heptane, which is a linear hydrocarbon with 7 carbon atoms and 16 hydrogen atoms. However, in the name of the hydrocarbon compound given in the question: 2,3-dimethylheptane;

- Two methyl groups (CH3) has a substituted two hydrogen atoms specifically at carbon 2 and 3 respectively. Therefore, the new chemical formula of 2,3-dimethylheptane will be: C7H14(CH3)2

Ok so N2+O2=2NO and my delta h is 180.5 kJ I need to know. If I react 10 g of nitrous gas with excess oxygen how many grams of Nitrogen monoxide will be produced

Answers

Answer:

21.6 grams

Explanation:

N₂ + O₂ → 2NO

First we convert 10 g of N₂ into moles, using its molar mass:

10 g ÷ 28 g/mol = 0.36 mol N₂

Then we convert 0.36 moles of N₂ into moles of NO, using the stoichiometric coefficients of the balanced reaction:

0.36 mol N₂ * [tex]\frac{2molNO}{1molN_2}[/tex] = 0.72 mol NO

Finally we convert 0.72 NO moles into grams, using its molar mass:

0.72 mol NO * 30 g/mol = 21.6 g

Karl-Anthony is trying to plate gold onto his silver ring. He constructs an electrolyte cell using his ring as one of the electrodes. He runs this cell for 90.6 minutes at 213.8 mA. How many moles of electrons were transferred in this process?

Answers

Answer:

0.012 mole of electron

Explanation:

From the question given above, the following data were obtained:

Time (t) = 90.6 minutes

Current (I) = 213.8 mA

Number of mole of electrons =?

Next, we shall convert 90.6 mins to seconds. This can be obtained as follow:

1 min = 60 s

Therefore,

90.6 mins = 90.6 × 60

90.6 mins = 5436 s

Next, we shall convert 213.8 mA to A. This can be obtained as follow:

1000 mA = 1 A

Therefore,

213.8 mA = 213.8 mA × 1 A / 1000 mA

213.8 mA = 0.2138 A

Next, we shall determine the quantity of electricity used in the process. This can be obtained as follow:

Time (t) = 5436 s

Current (I) = 0.2138 A

Quantity of electricity (Q) =?

Q = it

Q = 0.2138 × 5436

Q = 1162.2168 C

Next, the equation for the reaction.

Au⁺ + e —> Au

From the balanced equation above,

1 mole of electron was transferred.

Recall:

1 faraday = 96500 C = 1 e

Thus,

96500 C of electricity is needed to transfer 1 mole of electron.

Finally, we shall determine the number of mole electrons transferred by the application of 1162.2168 C of electricity. This can be obtained as follow:

96500 C of electricity is needed to transfer 1 mole of electron.

Therefore,

1162.2168 C of electricity will transfer = 1162.2168 / 96500 = 0.012 mole of electron

Thus, 0.012 mole of electron was transferred in the process.

Following are the calculation to the moles of electrons that transferred in the process:

Given

Current flows

time[tex]= 90.6\ min = 90.6 \times 60\ sec= 5436 \ sec\\\\[/tex]

For Step 1:

So:

Following are the calculation to the charges of electrons:

Following are the calculation to the electrons transferred:
