2. These compounds are water soluble if they have fewer than four carbon atoms.
3. When comparing ethers and alcohols of similar molecular weights, these compounds have the lower boiling point.

Answers

Answer 1

Explanation:

1. Only alcohols forms hydrogen bond  between themselves and with other compounds containing an O-H, N-H, or F-H bond, such as water.

2. Alcohols up to 4 carbons are miscible in water because they have hydrogen bonded to oxygen and can form hydrogen bond with water. However, it is not possible for ethers.

3. When comparing ethers and alcohols of similar molecular weights, ethers have lower boiling point than alcohol. This is because of the presence of hydrogen bond in alcohols.

Answer 2

The given statements can be classified as a property of both(ether and alcohol), both(ether and alcohol), and ether, respectively.

The given property of ethers, alcohols, or both ethers and alcohols are classified as:

This statement is a property of both ethers and alcohols. Both ethers and alcohols can form hydrogen bonds due to the presence of oxygen atoms in their molecules, which can interact with other compounds containing O-H, N-H, or F-H bonds, such as water.This statement is a property of both ethers and alcohols. Both ethers and alcohols can be water-soluble if they have fewer than four carbon atoms. The presence of the oxygen atom in ethers and alcohols allows them to form hydrogen bonds with water molecules, increasing their solubility.This statement is a property of ethers. When comparing ethers and alcohols of similar molecular weights, ethers generally have lower boiling points than alcohols. This is because ethers do not have hydrogen atoms directly bonded to the oxygen atom, which reduces the strength of intermolecular hydrogen bonding compared to alcohols. As a result, ethers have weaker intermolecular forces and lower boiling points.

Hence, the statements can be classified as shown above.

Answers

Answer:

480.0 mL

Explanation:

Step 1: Given data

Initial volume (V₁): 500.0 mLInitial temperature (T₁): 27.0 °CFinal volume (V₂): ?Final temperature (T₂): 15.0 °C

Step 2: Convert the temperatures to the Kelvin scale

We will use the following expression.

K = °C + 273.15

K = 27.0°C + 273.15 = 300.2 K

K = 15.0°C + 273.15 = 288.2 K

Step 3: Calculate the final volume

Assuming ideal behavior and constant pressure, we can calculate the final volume using Charles' law.

V₁ × T₂ = V₂ × T₁

V₂ = V₁ × T₂ / T₁

V₂ = 500.0 mL × 288.2 K / 300.2 K = 480.0 mL

How many moles would be present in a gas contained in a 100.0 mL vessel at 25.0oC at a pressure of 2.50 atm?

Answers

Answer:

n = 0.0102 mol.

Explanation:

Hello there!

In this case, according to the ideal gas law, which allows us to set up a relationship among volume, pressure, temperature and moles, we can define it as:

[tex]PV=nRT[/tex]

Thus, given the volume in liters (0.1000 L), temperature in kelvins (298.15 K) and pressure in atmospheres (2.50 atm), we can solve for moles as shown below:

[tex]n=\frac{PV}{RT}[/tex]

Thereafter, we plug in the aforementioned values to obtain:

[tex]n=\frac{2.50atm*0.1000L}{0.08206\frac{atm*L}{mol*K}*298.15K}\\\\n=0.0102mol[/tex]

Answers

Answer:

pOH = 11.5

[H⁺] = 0.003 M

[OH⁻] = 3 × 10⁻¹² M

Explanation:

The computation is shown below:

Given that

pH = 2.5

Based on the above information

We know that

pH + pOH = 14  ⇒  pOH = 14 - pH

pOH = 14 - 2.5

pOH = 11.5

[H⁺] = 10^(-pH) = 10^(-2.5)

[H⁺] = 0.003 M

[OH⁻] = 10^(-pOH)

= 10^(-11.5)

= 3 × 10⁻¹² M

[OH⁻] = 3 × 10⁻¹² M

Hence, the above represents the answer

Calculate the number of copper atoms in a 63.55 g
sample of copper.​

Answers

Answer:

there are N_A, "Avogadro's number" of copper atoms in a 63.55*g mass of copper wire. And N_A, "Avogadro's number" = 6.022xx10^23 individual copper atoms. I look on the Periodic Table, and at Z=29, i.e. copper, the quoted atomic mass is 63.55*g.

Explanation:

One mole of every substance contains 6.022×10²³ atoms. The atomic mass of copper is 63.55 g. Thus it is one mole of copper which contains copper 6.022×10²³ atoms.

What is copper?

Copper is 29th element in periodic table. It is a transition metal classified into d-block. Transition metals are named so because they in between the metals and non-metals in periodic table.

Transition metals have varying oxidation state. Copper exists in +1, +2 and +3 oxidation states.

Any substance containing 6.022×10²³ atoms is called one mole of that substance. This number is called Avogadro number. Hence one mole of each element contains avogadro number of its atoms.

Similarly one mole of each compound contains 6.022×10²³ number of molecules. Here, the atomic mass of copper is 63.55 g. That is one mole of copper weighs 63.55 g. Hence, number of atoms in 63.55 g of copper is 6.022×10²³ atoms.

Aqueous copper (II) sulfate reacts with aqueous potassium fluoride to produce
a precipitate of copper (II) phosphate and aqueous potassium sulfate.

Answers

Answer:

CuSO₄(aq) + 2 KF(aq) = CuF₂ + K₂SO₄

Explanation:

The question is missing but I think it must be about writing and balancing the equation.

Let's consider the unbalanced equation for the reaction that occurs when aqueous copper (II) sulfate reacts with aqueous potassium fluoride to produce  a precipitate of copper (II) fluoride (I fixed a mistake here) and aqueous potassium sulfate. This is a double displacement reaction.

CuSO₄(aq) + KF(aq) = CuF₂ + K₂SO₄

Since only K and F atoms are not balanced, we will get the balanced equation by multiplying KF by 2.

CuSO₄(aq) + 2 KF(aq) = CuF₂ + K₂SO₄

what type of forces are unequal forces that cause a change in an object's motion such as speed or direction

Answers

Answer:

Unbalanced forces are not equal, and they always cause the motion of an object to change the speed and/or direction that it is moving.

Explanation:

When two unbalanced forces are exerted in opposite directions, their combined force is equal to the difference between the two forces.

The magnitude and direction of the net force affects the resulting motion

This combined force is exerted in the direction of the larger force

For example, if two students push on opposite sides of a box sitting on the floor, the student on the left pushes with less force (small arrow) on the box than the student on the right side of the box (long arrow).

The resulting action (net force: smaller arrow to the right of the = shows that the box will change its motion in the direction of the greater force

If unbalanced forces are exerted in the same direction, the resulting force (net force) will be the sum of the forces in the direction the forces are applied.

When forces act in the same direction, their forces are added. When forces act in opposite directions, their forces are subtracted from each other.

Unbalanced forces also cause a nonmoving object to change its motion

If there is no net force acting on the object, the motion does not change. If there is a net force acting on an object, the speed of the object will change in the direction of the net force.

A diver takes a balloon with a volume of 2.5Lfrom the surface, where the pressure is 1.0 atm, to a depth of 20m, where the pressure is 3.0 atm. What happen to the volume of the balloon? What if the end of the subnerged balloon is on a long pipe that goes to the surface and is attached to another balloon?

Answers

Answer:

The explanation is given below:

Explanation:

As we know that the volume is inversely proportional to the volume. If the pressure is rising from 1 atm to 3 atm so the volume of the ballon would decrease

P_1V_1 = P_2V_2

1.0 × 2.5L = 3 × V_2

V_2 = 0.833L

Since the air is moving from high pressure to low pressure and the two ballons are interconnected via a long pipe so the movement of the air is from bottom to top

Determine the enthalpy of neutralization in Joules/mmol for a solution resulting from 19 mL of 1 M NaOH solution and 19 mL of a HCl with the same molarity. If separately, each had a temperature of 28.6 degrees Celsius, and upon addition, the highest temperature reached by the solution was graphically determined to be 37.3 degrees Celsius. Round to the nearest whole number.

Answers

Answer:

[tex]\Delta _{neutralization}H=-73\frac{J}{mmol}[/tex]

Explanation:

Hello there!

In this case, by considering this calorimetry problem, it is possible to realize that the heat released by the reaction between HCl and NaOH is absorbed by the reaction mixture, which can be assumed to have the same density and specific heat of pure water; thus, we calculate this heat as a function of the specified temperature change:

[tex]Q_{rxn}=-Q_{solution}\\\\Q_{rxn}=-m_{solution}C_{solution}(T_2-T_1)[/tex]

Thus, we plug in the data, by also considering that the total volume of solution is 19mL+19mL=38mL:

[tex]Q_{rxn}=-(38mL*\frac{1g}{1mL} )(4.184\frac{J}{g\°C}) (37.3\°C-28.6\°C)\\\\Q_{rxn}=-1383.2J[/tex]

Next, since the reaction between NaOH and HCl is:

[tex]NaOH+HCl\rightarrow NaCl+H_2O[/tex]

Whereas there is 1:1 mole ratio of NaOH to HCl, we infer they both react with the same moles, defined by the volume and molarity:

[tex]n_{rxn}=0.019L*1mol/L\\\\n_{rxn}=0.019mol[/tex]

Finally, to compute the enthalpy of neutralization we divide the total heat due to the reaction by the reaction moles to obtain:

[tex]\Delta _{neutralization}H=\frac{Q_{rxn}}{n_{rxn}=}\\\\ \Delta _{neutralization}H=\frac{-1383.23J}{0.019mol}\\\\\Delta _{neutralization}H=-72801.6\frac{J}{mol}*\frac{1mol}{1000mmol}\\\\\Delta _{neutralization}H=-73\frac{J}{mmol}[/tex]

Answers

Molarity = moles of solute/volume of solution in liters.

From this relation, we can figure out the number of moles of solute by multiplying the molarity of the solution by the volume in liters.

We have 53.1 mL, or 0.0531 L, of a 12.5 M, or 12.5 mol/L, solution. Multiplying 12.5 mol/L by 0.0531 L, we obtain 0.664 moles. So, in this volume of solution, there are 0.664 moles of solute (HCl).
