Explanation:

We were told that one of two different oxidizing agents were used H2CrO4 and H2SO4 or PCC/CH2Cl2.

Now, we must know that when we use H2CrO4 and H2SO4, primary alcohols are converted to aldehydes and then to carboxylic acids while secondary alcohols are converted to ketones.

When we use PCC/CH2Cl2 primary alcohols are converted to aldehydes and does not move further to convert to carboxylic acids while secondary alcohols are converted to ketones.

Recall that tertiary alcohols are not oxidized at all.

Answer:

0.71 g/mL

The liquid is diethylamine

Explanation:

Mass of the liquid = 1.23 kg of 1.23 * 10^3 g

Volume of the liquid = 1737.cm3

Let us remember that density is obtained as;

Density= mass/volume

Density= 1.23 * 10^3 g/1737cm^3

Density= 0.71 g/cm^3

Since we know that 1 mL=1 cm3 . So, 1 g/mL=1 g/cm3

So we can also write;

Density= 0.71 g/mL

The liquid is diethylamine

Explanation:

Esterification is a reaction of an alkanol and an alkanoic acid to yield an ester and water as products. It is analogous to inorganic neutralization reaction.

The process may be acid catalyzed. As mentioned in the question, the process of ester formation between pentanoic acid and n‑propanol first involves the carbonyl in going through an sp3 hybridized intermediate before returning to sp2 hybridized state in the product.

The image of the neutral form of this intermediate as well as the final structure of the ester are both shown in the image attached to this answer.

Answer:

Elements with the same number of electrons in their outermost shell show similar chemical properties. Example 1: Fluorine, chlorine, bromine, and iodine each have 7 electrons in their outermost shell. These so-called halogens are also quite similar in their chemical behavior.

Answer:

47 L will be the volume STP

Answer:

118.776 mmHg

Explanation:

The equation of the reaction is;

C4H10(g) + 13/2 O2(g) ------> 4CO2(g) + 5H20(g)

Now the mole ratio  according to the balanced reaction equation is;

1 : 6.5 : 4 : 5

Hence, the total number of moles present = 1 + 6.5 + 4 + 5 = 16.5 moles

Mole fraction of water vapour = 5/16.5 = 0.303

We also know that;

Partial pressure= mole fraction * total pressure

Partial pressure of H20(g) = 0.303 *  392 mmHg = 118.776 mmHg

The pressure (in mmHg) of water vapor is 118.78 mmHg

Butane reacts with oxygen according to the following equation

2C₄H₁₀ + 13O₂ —> 8CO₂ + 10H₂O

Mole fraction = mole / total mole

Mole fraction of water = 10 / 33

Mole fraction of water = 0.303

Partial pressure = mole fraction × total pressure

Partial pressure of water = 0.303 × 392

Partial pressure of water = 118.78 mmHg

Answer:

5.88 dL = 0.588 litre

Explanation:

We need to find a conversion from 5.88 dL to liters.

We know that the conversion is as follows :

1 deciliter = 0.1 litre

To find 5.88 dL to liters, we use the unitary method. So,

5.88 dL= (0.1×5.88) litre

5.88 dL = 0.588 litre

So, there are 0.588 liters in 5.88 dL.

tin nitrite Formula:Sn(NO2)2

The formula for tin (II) nitrite Sn(NO2)2.

Two atoms together chemically form a molecule. The chemical formula for a molecular compound's molecular formula lists the variety of atoms that make up the molecule.

A subscript under oxygen in CO2, for instance, indicates that there are two oxygen atoms present, but a subscript under carbon indicates that there is just one carbon atom present.

A nitronium salt is produced when tin(IV) nitrate and trifluoroacetic acid anhydride combine. Trifluoroacetic acid produces a similar molecule when it is solvated with it.

The number of each atom contained in a given molecule is indicated by the molecule's molecular formula. In essence, it is a list of the elements that are present in a molecule and how many of each there are.

Therefore, The formula for tin (II) nitrite Sn(NO2)2.

What is Charge ?

Charge is a basic property of matter that is associated with the presence or absence of electrons. Objects can have positive or negative charge, or they can be neutral, which means they have an equal number of positive and negative charges. In physics, charge is one of the fundamental concepts used to explain the behavior of matter and energy in the universe. The interaction between charges is described by Coulomb's law, which states that the force between two charges is proportional to the product of their charges and inversely proportional to the square of the distance between them.

Answer:

the answer is Covalent compounds separate into neutral molecules when they dissolve in water.

Explanation: covalent doesn’t conduct electricity in water

The common salt transforms the distilled water into an electrical conductor. But sugar molecule is a covalent compound which dissolve in water. So the white sugar does not show any conductivity.

The electrical conductors are defined as the materials which allow electricity to flow through them easily. The property of conductors which allow them to conduct electricity is defined as the conductivity. The metals are good conductors of electricity.

The distilled water does not contain any contaminants and it is incapable of conducting even very minute amount of electricity. But during the addition of ordinary salt or sodium chloride to the distilled water, it becomes electrically conductible.

The presence of chlorine and sodium ions makes the distilled water to conduct electricity. Here sugar is a covalent compound which separate into neutral molecules when they dissolve in water. So covalent compounds does not conduct electricity.

Answer:

Is there supposed to be a picture??

Explanation:

Answer:

781×10¯² g of MgCl₂.

Explanation:

The balanced equation for the reaction is given below:

Mg + 2HCl —> MgCl₂ + H₂

Next, we shall determine the mass of HCl that reacted and the mass of MgCl₂ produced from the balanced equation. This is illustrated below:

Molar mass of HCl = 1 + 35.5

= 36.5 g/mol

Mass of HCl from the balanced equation = 2 × 36.5 = 73 g

Molar mass of MgCl₂ = 24 + (35.5×2)

= 24 + 71

= 95 g/mol

Mass of MgCl₂ from the balanced equation = 1 × 95 = 95 g

SUMMARY:

From the balanced equation above,

73 g of HCl reacted to produce 95 g of MgCl₂.

Finally, we shall determine the mass of MgCl₂ produced by the reaction of 6 g of HCl. This can be obtained as follow:

From the balanced equation above,

73 g of HCl reacted to produce 95 g of MgCl₂.

Therefore, 6 g of HCl will react to produce = (6 × 95)/73 = 781×10¯² g of MgCl₂.

Thus, 781×10¯² g of MgCl₂ were obtained from the reaction.

Answer:

The ratio of f at the higher temperature to f at the lower temperature is 5.356

Explanation:

Given;

activation energy, Ea = 185 kJ/mol = 185,000 J/mol

final temperature, T₂ = 525 K

initial temperature, T₁ = 505 k

Apply Arrhenius equation;

[tex]Log(\frac{f_2}{f_1} ) = \frac{E_a}{2.303 \times R} [\frac{1}{T_1} -\frac{1}{T_2} ][/tex]

Where;

[tex]\frac{f_2}{f_1}[/tex]  is the ratio of f at the higher temperature to f at the lower temperature

R is gas constant = 8.314 J/mole.K

[tex]Log(\frac{f_2}{f_1} ) = \frac{E_a}{2.303 \times R} [\frac{1}{T_1} -\frac{1}{T_2} ]\\\\Log(\frac{f_2}{f_1} ) = \frac{185,000}{2.303 \times 8.314} [\frac{1}{505} -\frac{1}{525} ]\\\\Log(\frac{f_2}{f_1} ) = 0.7289\\\\\frac{f_2}{f_1} = 10^{0.7289}\\\\\frac{f_2}{f_1} = 5.356[/tex]

Therefore, the ratio of f at the higher temperature to f at the lower temperature is 5.356
