Answer:

3) 2KOH(aq) + H2SO4(aq) ⇒ K2SO4(aq) + 2H2O(l)

Explanation:

KOH is a strong base and a H2SO4 is a strong acid. The two react in a neutralization reaction, producing a salt and water.

Answer:

See explanation and image attached

Explanation:

The mechanism of this reaction is shown in the image attached. The image was obtained from HomeworkLib.

The first step in the reaction is protonation and loss of -OH2. A carbocation is now created which undergoes a 1,2 hydride shift. This yields a tertiary carbocation which is more stable.

A racemic mixture of two products, major and minor are now obtained as shown.

Answer:

A reaction that can only move towards the right.

Explanation:

For a reversible reaction when one of the products of the reaction is removed the reaction moves towards right hand side. More and more reactants will be converted into products. This will nullify the effect of removal of product.

Answer:

Precipitation falls in liquid and solid

Evaporation changes liquid water to gas

Explanation:

Precipitation exists in snow, rain, sleet, many forms liquid or solid but NOT gas.

Evaporation is from a liquid to a gas change, also called vaporization.

Explanation:

The reaction of phenol with bromine is known as bromination of phenol. Solvent has great influence on the reaction. In different solvents, different products are obtained. The action of bromine on phenol can be explained as:

Reaction with bromine in water:—-

Reaction with bromine in water

Phenol reacts with bromine water to give 2,4,6-tribromophenol.

In water, ionisation is facilitated. Phenol gets ionised to form phenoxide ion, which is even better ortho,para-directing. Bromine also gets ionised to a larger extent to form a large number of bromonium ions. And Bromine ions are highly stabilized in ionic solvents. So the formation of strong o,p-directing group and stabilization of Br+ enhances the formation of tribromophenol.

Reaction with bromine in CS2:—-

Reaction with bromine in non-polar organic solvents

Phenol reacts with bromine in a presence of Carbon disulphide to form a mixture of o-bromophenol and p-bromophenol. Among which p-bromophenol predominates. In CS2 ionisation is not facilitated that much. As it is a non-polar solvent it doesn't the Br+ on. Also −OH group is moderately o,p-directing. So as usual para-product is more formed.

Explanation:

1: 10 mol CO2

2: C10H24

3: 12 mol H2O

4: 0.5 mol

5: 16 mol O2

The compound is C5H10.

From the information  available in the question;

Number of moles of carbon dioxide = 440.00 g/44 g/mol = 10 moles

Number of moles of water vapor = 216.00 g/18 g/mol = 12 moles

Mass of carbon = 10 moles × 12 g/mol = 120 g of carbon

Moles of hydrogen = 12 moles  × 2 g/mol = 24 g of hydrogen

Number of moles of carbon = 120 g/12 g/mol = 10 moles

Number of moles of hydrogen = 24 g/1 g/mol =24 moles

Divide through by the lowest number of moles =

C - 10/10   H - 24/10

C - 1          H - 2

The empirical formula is CH2

Molar mass of the compound = 72 g/mol

[12 + 2(1)]n = 72

14n = 72

n = 5

The compound is C5H10.

Answer: 1. [tex]2C_8H_{18}(l)+25O_2(g)\rightarrow 16CO_2(g)+18H_2O(g)[/tex]

2. The volume of carbon dioxide gas that is produced is 537 L

Explanation:

1. Combustion is defined as the type of chemical reaction where a hydrocarbon is combusted in the presence of oxygen to give carbon dioxide and water.

The balanced reaction for combustion of octane is:

[tex]2C_8H_{18}(l)+25O_2(g)\rightarrow 16CO_2(g)+18H_2O(g)[/tex]

2.

To calculate the moles :

[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]   [tex]\text{Moles of octane}=\frac{0.330\times 1000g}{114.23g/mol}=2.89moles[/tex]

According to stoichiometry:

2 moles of octane produce = 16 moles of carbon dioxide

2.89 moles of octane produce = [tex]\frac{16}{2}\times 2.89=23.1moles[/tex] of carbon dioxide

According to ideal gas equation:

[tex]PV=nRT[/tex]

P = pressure of gas = 1 atm

V = Volume of gas = ?

n = number of moles = 23.1

R = gas constant =[tex]0.0821Latm/Kmol[/tex]

T =temperature =[tex]10.0^0C=(10+273)K=283K[/tex]

[tex]V=\frac{nRT}{P}[/tex]

[tex]V=\frac{23.1\times 0.0821Latm/K mol\times 283K}{1atm}=537L[/tex]

Thus the volume of carbon dioxide gas that is produced is 537 L

Answer: The suspected and crime scene fingerprint patterns are similar which means they belong to the same individual.

Explanation:

A:  Ending ridge between two lines forming a loop like structure common in both suspected and crimes scene patterns.

B: Bifurcation which includes the formation of fork like shape of the ridge.

C: Island is a dot or point like structure which is common in both patterns.

D: It includes delta which is seen in the case of loop and whorl patterns of the fingerprint in loop there is only one delta and in case of whorl there are two deltas. The delta have an island and a bifurcation in it which is common in both patterns of the fingerprints.

E: Intersection occurs when two ridges changes their directions. It is common in the two patterns.

Answer:

0.0986M is the concentration of the Na₂S₂O₃ solution

Explanation:

Potassium iodate, KIO₃, reacts with sodium thiosulfate, Na₂S₂O₃, as follows:

KIO₃ + 6Na₂S₂O₃ +5KI + 3H₂SO₄ → 3H₂O + 3K₂SO₄ + 3Na₂S₄O₆ + 6NaI

To solve this question we must find the moles of sodium thiosulfate that reacts as follows:

Moles KIO₃:

0.0250L * (0.0100mol / L) = 2.5x10⁻⁴moles KIO₃

Moles Na₂S₂O₃:

2.5x10⁻⁴moles KIO₃ * (6mol Na₂S₂O₃ / 1mol KIO₃) = 1.5x10⁻³ moles Na₂S₂O₃

Molar concentration:

1.5x10⁻³ moles Na₂S₂O₃ / 0.01521L =

Answer: The final pressure is 0.81 kPa

Explanation:

The combined gas equation is,

[tex]\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}[/tex]

where,

[tex]P_1[/tex] = initial pressure of gas = 0.58 kPa

[tex]P_2[/tex] = final pressure of gas = ?

[tex]V_1[/tex] = initial volume of gas = v

[tex]V_2[/tex] = final volume of gas = [tex]v-\frac{40}{100}\times v=0.6v[/tex]

[tex]T_1[/tex] = initial temperature of gas = [tex]25^0C=(25+273)K=298K[/tex]

[tex]T_2[/tex] = final temperature of gas = [tex]-22^0C=(-22+273)K=251K[/tex]

Now put all the given values in the above equation, we get:

[tex]\frac{0.58\times v}{298}=\frac{P_2\times 0.6v}{251}[/tex]

[tex]P_2=0.81kPa[/tex]

The final pressure is 0.81 kPa
