using reactions from this chapter as well as from the previous chapter, show how 1-hexanol can be converted into a grignard reagent.

Answers

Answer 1

In order to create the Grignard reagent from 1-hexanol, the matching halide must first be converted from it. You can accomplish this by reacting 1-Hexanol with a potent acid,

Like HCl. The appropriate alkyl chloride will be created during the reaction, and this alkyl chloride can then be combined with a primary alkyl halide, such as magnesium bromide, to create the Grignard reagent. The Grignard reagent will have the generic formula RMgX, where R is the alkyl group from 1-Hexanol and X is the halide. The reaction is normally carried out in an ether solvent. The synthesis of alcohols and other organic molecules can then be accomplished using the Grignard reagent.

to find the density of stopper I weighted it and found its mass to 4.8g. After that I filled a graduated cylinder with 32.1mL of water. After adding the stopper, the water level rose to 39.2mL. What is the density of the stopper?

Answers

Answer:

0.68g/ml

Explanation:

The density of an object is its mass per unit volume. It is calculated using the formula

Density = mass / volume

Mass of stopper weighed = 4.8g

The volume of stopper can be got by subtracting the (volume of water) from the (volume of water+stopper) i.e.

= 39.2ml - 32.1ml

= 7.1ml

Volume of stopper = 7.1ml

Density of stopper= 4.8/7.1

Density= 0.676056

Therefore, the density of the stopper is 0.68g/ml

The standard reduction potentials for these half-reactions are:

E°reduction(Pb4+/Pb2+) = -0.13 V

E°reduction(Co3+/Co2+) = +1.82 V

We then calculate as:

E°cell = E°reduction (Co3+/Co2+) - E°reduction (Pb4+/Pb2+)

E°cell = (+1.82 V) - (-0.13 V)

A 12.2 mL sample of liquid was found to have a mass of 10.4 g. Calculate the density of this liquid ( in g/mL).

Answers

Answer:

d=m/

Explanation:

d is density, m is mass, v is volume

Given: m =10.4g, v=12.2mL

substituting in equation,

d=10.4/ 12.2

d=0.8524g/mL

To learn more about density:

The density of the liquid is 0.852 g/mL.

To calculate the density of the liquid, we need to use the formula:

Density = Mass / Volume

Given that the mass of the liquid is 10.4 g and the volume is 12.2 mL, we can substitute these values into the formula:

Density = 10.4 g / 12.2 mL

Simplifying this expression, we find:

Density = 0.852 g/mL

Density is a physical property of a substance and is defined as the amount of mass per unit volume. In this case, the density tells us that for every milliliter of the liquid, there is 0.852 grams of mass. The units of grams per milliliter (g/mL) indicate that the density is a ratio of mass to volume.It is important to note that the density of a substance can vary with temperature, so this value is only valid under the conditions at which the measurement was made. Additionally, the density can provide valuable information about the identity of a substance, as different substances have different densities.

(A) It is thermodynamically unfavorable
(B) It is thermodynamically favorable and is driven by Delta S degree only.
(C) It is favorable and is driven by Delta H degree only.
(D) It is thermodynamically favorable and is driven by both Delta H degree and Delta S degree

Answers

Answer:

(C) It is favorable and is driven by ΔH° only.

Explanation:

Let's consider the following balanced equation.

2 Na₂O₂ + S + 2 H₂O → 4 NaOH + SO₂

To determine whether it will be favorable or not at 298 K, we need to calculate the standard Gibbs free energy (ΔG°).

If ΔG° < 0, the reaction will be favorable.If ΔG° > 0, the reaction will be unfavorable.

We can calculate ΔG° using the following expression.

ΔG° = ΔH° - T.ΔS°

As we can see from the expression above, the favorability will be driven if ΔH° < 0 and if ΔS° < 0. Since ΔH° = -610 kJ/mol and ΔS° = -73 J/K.mol, the favorability will be driven by ΔH°. Now, let's calculate the overall favorability.

ΔG° = ΔH° - T.ΔS°

ΔG° = -610 kJ/mol - 298 K.(-0.073 kJ/K.mol) = -588 kJ/mol

The reaction is favorable and is driven by ΔH° only.

What mass of NaCl is in 1.25L of 0.1035M solution?

Answers

Answer:

Explanation:

To determine the mass of NaCl in 1.25L of 0.1035M solution, we can use the formula:

mass = concentration x volume x molar mass

where concentration is in molarity (M), volume is in liters (L), and molar mass is in grams per mole (g/mol).

The molar mass of NaCl is 58.44 g/mol.

Plugging in the given values, we get:

mass = (0.1035 M) x (1.25 L) x (58.44 g/mol)

mass = 7.3188 g

So, there is approximately 7.3188 grams of NaCl in 1.25L of 0.1035M solution.

When excess hydrogen is passed over 4.5g of heated oxide of metal X, 3.6 g of X are finally left. Calculate the RAM of X and the minimum volume of hydrogen (at stp) used in this reaction XO + H₂(g) → X + H₂O(g) ​

Answers

Answer:

We can use the information given in the problem to calculate the RAM (relative atomic mass) of X and the minimum volume of hydrogen used in the reaction.

First, we need to calculate the mass of oxygen in the oxide XO:

mass of oxygen = mass of oxide - mass of metal

mass of oxygen = 4.5 g - 3.6 g

mass of oxygen = 0.9 g

Next, we can use the mass of oxygen to calculate the number of moles of oxygen:

moles of oxygen = mass of oxygen / molar mass of oxygen

moles of oxygen = 0.9 g / 16.00 g/mol

moles of oxygen = 0.05625 mol

Since the oxide XO is formed by the combination of X and oxygen, we can assume that the mass of X in the oxide is equal to the mass of the oxide minus the mass of oxygen:

mass of X = mass of oxide - mass of oxygen

mass of X = 4.5 g - 0.9 g

mass of X = 3.6 g

We can use the mass of X and the number of moles of oxygen to calculate the number of moles of X:

moles of X = mass of X / atomic mass of X

moles of X = 3.6 g / atomic mass of X

Combining this with the stoichiometry of the reaction, which tells us that 1 mole of XO reacts with 1 mole of H2 to produce 1 mole of X and 1 mole of H2O, we can write:

moles of H2 = moles of X / 1 = (3.6 g / atomic mass of X) / 1

To determine the minimum volume of hydrogen at STP (Standard Temperature and Pressure), we can use the ideal gas law:

PV = nRT

where P is the pressure, V is the volume, n is the number of moles, R is the universal gas constant, and T is the temperature. At STP, the pressure and temperature are 1 atm and 273 K, respectively, and the universal gas constant is 0.08206 L atm/(mol K).

Substituting the given values and solving for V, we get:

V = nRT/P = [(3.6 g / atomic mass of X) / 1] * (0.08206 L atm/(mol K)) * 273 K / 1 atm

Simplifying and solving for the atomic mass of X, we get:

atomic mass of X = (3.6 g / V) * (1 mol/2 mol of H2) * (1 mol of XO/1 mol of X) * (16.00 g/mol of oxygen + atomic mass of X)

Substituting the given values, we get:

atomic mass of X = (3.6 g / V) * (0.5) * (1 / 1) * (16.00 g/mol + atomic mass of X)

Multiplying out, we get:

atomic mass of X = (1.8 g / V) * (16.00 g/mol + atomic mass of X)

Solving for atomic mass of X, we get:

atomic mass of X = (1.8 g / V) * 16.00 g/mol / (1 - 1.8 g / V)

Substituting V = 22.4 L (the volume of 1 mole of gas at STP), we get:

atomic mass of X = (1.8 g / 22.4 L) * 16.00 g/mol / (1 - 1.8 g / 22.4 L)

atomic mass of X ≈ 56.1 g/mol

Therefore, the RAM of X is approximately 56.1 g/mol, and the minimum volume of hydrogen used in the reaction is approximately 22.4 L at STP.

Answers

Answer:

141.89 dm^3

Explanation:

The equation of the reaction is;

2H2O2(aq) --------->2H2O(l) + O2(g)

Now , we are told that the mass of hydrogen peroxide decomposed was 315g. Number of moles of hydrogen peroxide in 315g of the substance is given by;

Number of moles= mass/molar mass

Molar mass of hydrogen peroxide= 34.0147 g/mol

Number of moles= 315g/34.0147 g/mol = 9.26 moles of hydrogen hydrogen peroxide.

From the reaction equation;

2 moles of hydrogen peroxide yields 1 mole of oxygen

9.26 moles of hydrogen peroxide yields 9.26 ×1/2 = 4.63 moles of oxygen

From the ideal gas equation;

Volume of the gas V= the unknown

Pressure of the gas P= 0.792 atm

Temperature of the gas= 23°C +273 = 296 K

Number of moles of oxygen = 4.63 moles of oxygen

R= 0.082atmdm^3K-1mol-1

Hence, from PV=nRT

V= nRT/P

V= 4.63 × 0.082 × 296/0.792 = 141.89 dm^3

5. You have 2 Liters of a 5 M Solution of H3PO4. How many grams are present?

Answers

Answer

979.94 grams

Explanation

Given:

Volume of solution = 2 L

Molarity = 5 M

What to find:

The mass in grams of H3PO4 present in the solution.

Step-by-step solution:

The first step is to calculate the moles of H3PO4 present using the molarity formula below:

\(\begin{gathered} Molarity=\frac{Moles}{Volume\text{ }in\text{ }L} \\ \\ \Rightarrow Moles=Molarity\times Volume\text{ }in\text{ }L \end{gathered}\)

Put the values of the given parameters into the formula to get the moles:

\(Moles=5M\times2L=10\text{ }mol\)

The moles of H3PO4 present in the solution = 10 mol.

Therefore, the mass present can be determined using the mole formula:

\(\begin{gathered} Moles=\frac{Mass\text{ }in\text{ }grams}{Molar\text{ }mass} \\ \\ \Rightarrow Mass\text{ }in\text{ }grams=Moles\times Molar\text{ }mass \end{gathered}\)

From the periodic table, the molar mass of H3PO4 can be known as 97.994 g/mol.

So putting moles = 10 mol and molar mass = 97.994 g/mol, then the mass is:

\(Mass=10\text{ }mol\times97.994\text{ }g\text{/}mol=979.94\text{ }grams\)

Therefore, the mass in grams of H3PO4 present in the solution = 979.94 grams.

Since it has expanded, it is less dense than the fluid next to it, so it rises above it. In the atmosphere, with sea and land breezes, as either the ground or sea is warmer than the other, it heats the air above it. This air rises above the cooler air next to it.

What is true about dominant alleles? a They almost never appear as the trait. b They appear as the trait only when there are two of them c They appear as the trait over a recessive allele d They appear as the trait if there is not recessive allele

Answers

They appear as the trait over a recessive allele. Statement C) is true about the dominant alleles.

Dominant alleles are genetic variants that, when present in an individual's genotype, are expressed phenotypically, meaning they determine the visible or observable traits. Dominant alleles are represented by capital letters, while recessive alleles are represented by lowercase letters in genetics.

In terms of inheritance, if an individual has at least one copy of the dominant allele, it will be expressed in the phenotype, regardless of the presence of a recessive allele. This is because dominant alleles exert their influence over recessive alleles, thus "dominating" their expression.

To illustrate this, let's consider a specific example using a trait controlled by a single gene with two possible alleles: dominant (A) and recessive (a). If an individual is homozygous dominant (AA), meaning they possess two copies of the dominant allele, the dominant trait will be expressed.

However, if an individual is homozygous recessive (aa), with two copies of the recessive allele, the recessive trait will be expressed since there are no dominant alleles to override it.

Therefore, dominant alleles appear as the trait over recessive alleles, regardless of the presence or absence of a recessive allele. The presence of even a single copy of the dominant allele is sufficient for its expression in the phenotype. Option C

Formula
4 points
P₁V₁ = P₂V₂
P₁ = first pressure
P2 = second pressure
V₁ = first volume

Answers

The gas law that is calculated with the pressure and volume variables at a constant temperature is Boyle's Law. Boyle's Law states that the pressure (P) of a gas is inversely proportional to its volume (V) when temperature (T) is held constant.

Mathematically, it is expressed as P₁V₁ = P₂V₂, where P₁ and V₁ represent the initial pressure and volume, and P₂ and V₂ represent the final pressure and volume.According to Boyle's Law, if the volume of a gas is reduced while keeping the temperature constant, the pressure will increase proportionally.

Similarly, if the volume is increased, the pressure will decrease. This relationship holds as long as the temperature remains constant throughout the process. Boyle's Law is one of the fundamental gas laws and provides insights into the behavior of gases under changing pressure and volume conditions at a constant temperature.
