write the structure of the major organic products formed in the reaction of ozonide with dimethyl sulfide (ch3)2s.

Answers

Answer 1

The following are the primary organic compounds generated by the reaction of ozonide with dimethyl sulphide (CH3)2S: (CH3)2SO dimethyl sulfoxide, and (CH3)2SO2 dimethyl sulfone.

When ozonide reacts with dimethyl sulphide (CH3)2S, two main organic products are formed: methyl sulfoxide (CH3SO) and dimethyl sulfoxide (CH3)2SO.

To generate the end products, the sulphide sulphur atom is nucleophilically added to the ozonide intermediate, followed by the migration of a methyl group and a proton shift.

These organic products' structures can be written as follows:

CH3SO (methyl sulfoxide): CH3-S-O

CH3-S(=O) dimethyl sulfoxide (CH3)2SO-CH3

solid lithium hydroxide is used in space vehicles to remove the carbon dioxide gas exhaled by astronauts. the hydroxide reacts with carbon dioxide to form solid lithium carbonate and liquid water. how many pounds (2.2 pounds per kilogram, 1000 grams per kilogram) of lithium hydroxide must be on board for three astronauts to spend 7 days in space, assuming each astronaut produces 1.1 kilograms of carbon dioxide per day? assume the reaction has a 100% yield.

Answers

3.794 lbs of LiOH must be on board for the three astronauts to spend 7 days in space.

First, let's calculate the total amount of CO2 produced by the three astronauts in 7 days:

1.1 kg/astronaut * 3 astronauts = 3.3 kg CO2 produced in 7 days

Next, let's find the moles of CO2 produced:

3.3 kg CO2 * 1000 g/kg = 3300 g CO2

1 mole of CO2 weighs 44 g, so:

3300 g / 44 g/mol = 75 moles CO2

The balanced equation for the reaction of LiOH with CO2 is:

LiOH + CO2 -> Li2CO3 + H2O

For every mole of CO2, 1 mole of LiOH is required, so:

75 moles LiOH needed

Finally, to find the weight in pounds, we need to convert moles to grams and then to pounds:

75 moles * 23 g/mol = 1725 g

1725 g / 1000 g/kg = 1.725 kg

1.725 kg * 2.2 lb/kg = 3.794 lbs of LiOH needed for the reaction.

cesium-139 undergoes radioactive decay by one mode and generates barium-139. what mode of decay is consistent with this product?

Answers

The product's beta decay mode is consistent.

Cesium-139 decays by beta decay to either the radioactive isotope of stable barium-139 or to barium-139m, which is a meta-stable form of barium with a half-life of roughly 30 years.

In the environment, cesium-139 decays by releasing beta particles. As mentioned earlier, barium-139m is the short-lived decay product of cesium-139. The latter isotope gives out moderately energetic gamma radiation, which afterwards transforms into a stable form of barium.

C degrades through a process known as beta decay. One of the neutrons which are in the carbon atom turns into a proton during this process, which results in the decay of a carbon atom into a nitrogen atom. By adding one more proton to the atom, this results in the formation of a nitrogen atom rather than a carbon atom.

which isomer of pentane has the lowest boiling point

Answers

The isomer of pentane which has the lowest boiling point is neo-pentane as it has a lower surface area due to its branched chain.

Pentane is an alkane which consists of five carbon atoms bound by single bonds. Pentane has three isomers namely n-pentane, iso-pentane and neo-pentane. Among these three isomers, neo-pentane has the lowest boiling point.

The boiling point of a particular alkane depends on the surface area of the molecule, that is, the higher the surface is, the higher will be the boiling point of that alkane. The branched-chain isomer of an alkane will have a lower surface area as compared to its straight-chain isomer and therefore the branched-chain isomer of the alkane will possess a lower boiling point than its straight-chain isomer.

Hence, we can say that the higher the number of branches, lower is the boiling point. Neo-pentane has the lowest boiling point among all the isomers of pentane.

Answers

Answer:

Explanation:The equation for the reaction between barium chloride and sulfuric acid is:

BaCl2(aq) + H2SO4(aq) -> BaSO4(s) + 2HCl(aq)

(a) Using the equation, we can calculate the number of moles of barium chloride and sulfuric acid:

n(BaCl2) = 0.04163 * 12.45 mL = 0.5138 mol

n(H2SO4) = 1.732 * 15.00 mL = 0.2601 mol

Since the ratio of barium chloride to sulfuric acid is 1:2, the limiting reagent (the reagent that determines the amount of product formed) is the sulfuric acid. The maximum amount of barium sulfate that can be formed is equal to the amount of sulfuric acid used, which is 0.2601 mol.

(b) To find the amount of barium chloride required to react with ammonium phosphate, we need to write the balanced equation for the reaction. The balanced chemical equation for the reaction between barium chloride and ammonium phosphate is not known.

(c) The equation for the reaction between barium chloride and potassium carbonate is:

BaCl2(aq) + K2CO3(aq) -> BaCO3(s) + 2KCl(aq)

Using the equation, we can calculate the number of moles of barium chloride and potassium carbonate:

n(BaCl2) = 0.04163 * 35.15 mL = 1.4506 mol

n(K2CO3) = 1.28 * 35.15 mL = 0.4536 mol

Since the ratio of barium chloride to potassium carbonate is 1:2, the limiting reagent (the reagent that determines the amount of product formed) is the potassium carbonate. The maximum amount of barium carbonate that can be formed is equal to half the amount of potassium carbonate used, which is 0.4536/2 = 0.2268 mol.

The volume of barium chloride is :

(a) 12.45 mL of 1.732 M sulfuric acid is 0.050 L.

(b) 15.00 g of the ammonium phosphate is 0.027 L.

(c) 35.15 mL of 1.28M the potassium carbonate is 0.018 L.

The molarity of the barium chloride = 0.4163 M

(a) The volume of sulfuric acid = 12.45 mL = 0.01245 L

The molarity = 1.732 M

Moles = molarity × volume

         = 1.732 × 0.01245

         = 0.021 mol

The volume of the BaCl₂ = moles / molarity

                                          = 0.021 / 0.4163

                                          = 0.050 L

(b)  3BaCl₂  +  2(NH₄)₃PO₄  ---->  Ba(PO₄)₂   +   6NH₄Cl

The mass of the ammonium phosphate = 15 g

The moles of ammonium phosphate = 15 / 149

                                                              = 0.100 mol

Moles of (NH₄)₃PO₄ = (2/3) 0.100

                                  = 0.066

The volume of the  BaCl₂  = 0.066 × 0.4163

                                            = 0.027 L

(c) The moles of the potassium carbonate = 0.03515 × 1.28

                                                                      = 0.044 mol

The volume of the BaCl₂ = moles / volume

                                         = 0.044 / 0.4163

                                        = 0.018 L.

a reaction has a rate law of rate = (1.25 m⁻²s⁻¹)[a][b]². what concentration of [b] would give the reaction a rate of 0.0891 m/s if the concentration of [a] is 0.250 m?

Answers

The reaction has a rate law of the rate = (1.25 m⁻²s⁻¹)[A][B]². The concentration of [B] will give the reaction of rate of 0.0891 m/s if the concentration of [A] is 0.250 M is [B] is 0.52 M.

The concentration of [A] = 0.250

The Rate = (1.25 m⁻²s⁻¹)[A][B]²

By solving the equation , we get :

0.0857 = 1.25 [A] [B]²

0.0857 = 1.25 × 0.250 × [B]²

0.0857 = 0.3125 [B]²

[B]² = 0.27424

[B] = 0.52 M

Thus, the concentration of the [B] is 0.52 M with the  reaction has a rate law of rate = (1.25 m⁻²s⁻¹)[A][B]².

Find the number of moles of calcium chloride required to react with 350 grams of silver nitrate - Really looking for a well written explanation with steps

Answers

Calcium chloride (CaCl2) and silver nitrate (AgNO3) react to form calcium nitrate (Ca(NO3)2) and silver chloride (AgCl) according to the following balanced equation:

CaCl2 + AgNO3 → Ca(NO3)2 + AgCl

In order to find the number of moles of calcium chloride required to react with 350 grams of silver nitrate, we can use the concept of stoichiometry. Stoichiometry is the study of the quantitative relationships between the reactants and products in a chemical reaction. By using the balanced equation and molar masses of the reactants and products, we can calculate the number of moles of one substance required to react with a certain number of moles of another substance.

Here's the step by step process:

Determine the molar mass of silver nitrate (AgNO3). The molar mass of AgNO3 is 169.87 grams/mole.

Convert the given mass of silver nitrate to moles. To do this, divide the mass by the molar mass:

350 grams AgNO3 / 169.87 grams/mole = 2.05 moles AgNO3

Use the stoichiometry of the balanced equation to determine the number of moles of calcium chloride required to react with 2.05 moles of silver nitrate. The coefficients in the balanced equation indicate the molar ratios between the reactants and products. In this case, the coefficients are 1:1, meaning that for every 1 mole of calcium chloride that reacts, 1 mole of silver nitrate also reacts. Therefore, the number of moles of calcium chloride required is 2.05 moles.

In conclusion, to react with 350 grams of silver nitrate, we need 2.05 moles of calcium chloride.

a 0.20 m sodium chlorobenzoate (nac7h4clo2) solution has a ph of 8.65. calculate the ph of a 0.20 m chlorobenzoic acid (hc7h4clo2) solution.

Answers

A 0.20 m sodium chlorobenzoate ([tex]NaC7H4ClO2[/tex]) solution has a pH of 8.65 the pH of a 0.20 m chloro-benzoic acid ([tex]HC7H4ClO2[/tex]) solution is 2.35

Given the concentration of sodium chlorobenzoate (M) = 0.2M

The pH of sodium chlorobenzoate ([tex]NaC7H4ClO2[/tex]) solution = 8.65

The pOH of the solution = 5.35

The concentration of chloro-benzoic acid ([tex]HC7H4ClO2[/tex]) solution = 0.2

The pH of chloro-benzoic acid ([tex]HC7H4ClO2[/tex]) solution = P

From the pH the  ([tex]NaC7H4ClO2[/tex]) is a weak base, so determine the Ka for C7H4ClO2. Then, [OH-]= 10^-5.35 = 4.5 * 10^-4M = x

Kb = (x)^2/(0.2 - x) = (4.5 * 10^-4)^2/(0.2- 4.5 * 10^-4) = 1 * 10^-10

The chloro-benzoic acid is a weak acid such that ka = kw/kb = 10^-14/10^-10 = 10^-4

Then, (x)^2/(0.2 - x) = 10^-4

x = [H+] = 4.5 * 10^-2M

pH = 2.35

Select the TRUE statements below regarding Friedel-Crafts reactions. a. Friedel- Crafts reactions are sensitive to the presence of electron-withdrawing groups on the benzene ring. Friedel-Crafts reactions give poor yields when a strong or moderately deactivating substituent is present on the benzene ring. b. The use of a primary, secondary, or tertiary amine group on the benzene ring results in a better yield because the Lewis acid used in the Friedel-Crafts reaction reacts with the lone pair on the nitrogen atom to form an adduct and these substances are strong activators toward EAS reactions. c. Aryl and vinyl halides do not readily form carbocations and are not used in Friedel-Crafts reactions. d. Polyalkylations are worrisome in the Friedel-Crafts alkylation reaction. An alkyl group is an activator, and when one alkyl group has been placed onto a benzene ring, this activates the ring for further alkylations. e. Polysubstitutions are a problem in the Friedel-Crafts acylation reaction. The acyl group is a deactivator toward EAS and does not promote a further acylation of the benzene ring.

Answers

Regarding Friedel-Crafts reactions, statements in options a and d are accurate.

In order to attach substituents to an aromatic ring, Charles Friedel and James Crafts created a series of reactions in 1877 known as the Friedel-Crafts reactions.Alkylation reactions and acylation reactions are the two primary categories of Friedel-Crafts processes. Both work by substituting electrophilic aromatics.

When water or any liquid i poured into a beaker and then more i added, will it DENSITY increae?
Be ure to add an EXPLANATION entence to your repone

Answers

When water or any liquid is poured into a beaker and then more is added, density will remain the same for any volume of water.

Density is defined as how much space an object or substance takes up (its volume) in relation to the amount of matter in that object or substance (its mass). The other way to put it is that density is the amount of mass per unit of volume.

The formula for density is given as,

Density = Mass / Volume

S.I. unit of mass is kg and S.I. unit of volume is m³. Hence, S.I. unit of density is given as kg / m³.

The density for any liquid is always fixed for any volume as it is a characteristic property of liquid.
