The buoyant force is one that acts against the weight of an object suspended in a fluid. The value of the buoyant force on each are:

i. Buoyant force on the cube of iron = 25.0 N

ii. Buoyant force on the cube of wood = 1.20 N

Upthrust is a force which acts against the direction of the weight of an object when suspended in a fluid. It acts majorly upwards against gravity, and it can be referred to as a buoyant force.

The amount of upthrust on object in a fluid sometimes depends on the density, volume and gravity acting on the object.

So that;

Upthrust = density x volume x gravity

Thus from the given question;

i. The buoyant force on the cube of iron can be determined by:

Upthrust = 7.86 x [tex]10^{3}[/tex] * 3.25 x [tex]10^{-4}[/tex] * 9.8

              =  25.034

Upthrust = 25.0 N

Therefore, the buoyant force on the cube of iron is 25.0 N.

ii. The buoyant force on the cube of wood can be determined by:

Upthrust = 3.73 x [tex]10^{2}[/tex] * 3.25 x [tex]10^{-4}[/tex] * 9.8

              = 1.1880

Upthrust = 1.20 N

Therefore, the buoyant force on the cube of wood is 1.20 N.

If 75J of heat are applied to 8.4 L of a gas at 732 mmHg and 298K, what is the final temperature, in K, of the gas? Cp for an ideal gas is 20.79 J/mol*K.

Answers

Answer:

309 K

Explanation:

Step 1: Convert the pressure to atm

We will use the conversion factor 1 atm = 760 mmHg.

732 mmHg × 1 atm/760 mmHg = 0.963 atm

Step 2: Calculate the moles (n) of the ideal gas

We will use the ideal gas equation.

P × V = n × R × T

n = P × V/R × T

n = 0.963 atm × 8.4 L/0.0821 atm.L/mol.K × 298 K

n = 0.33 mol

Step 3: Calculate the temperature change

We will use the following expression.

Q = n × Cp × ΔT

ΔT = Q/n × Cp

ΔT = 75 J/0.33 mol × 20.79 J/mol.K

ΔT = 11 K

Step 4: Calculate the final temperature

T = 298 K + 11 K = 309 K

e. Pb3(AsO4)2, Ksp = 4.0x10^-36

Answers

Answer:

a. PbSO4, Ksp = 1.7x10^-8.

Explanation:

Hello!

In this case, since the solubility product indicates how likely a solid is able to ionize and consequently dissolve in water, we can infer that the larger the solubility product Ksp, the more ions are able dissolve in water; therefore the proper answer goes with the largest Ksp, which is a. PbSO4, Ksp = 1.7x10^-8 since the power goes closer to 1 than the other options.

A sheet of aluminum measures 55.0 cm by 23.3 cm. If the volume is 2.90 cm^3 what is the thickness of the foil?

Express your answer with the appropriate units.

Answers

Answer:

0.0023 cm

Explanation:

The following data were obtained from the question:

Length (L) = 55 cm

Breadth (B) = 23.3 cm

Volume (V) = 2.9 cm³

Thickness (T) =?

Thus, we can obtain the thickness of the aluminum foil as illustrated below:

V = L × B × T

2.9 = 55 × 23.3 × T

2.9 = 1281.5 × T

Divide both side by 1281.5

T = 2.9/1281.5

T = 0.0023 cm

Therefore, the thickness of the aluminum foil is 0.0023 cm

Answers

The atomic radius trend on the Periodic Table is as follows:

- Atomic radius increases down a column (or group)

- Atomic radius decreases across rows (or periods) from left to right

Looking at my Periodic Table, calcium, chromium, cobalt and copper are in that order from left to right in the same period, which simplifies things significantly.

Since these elements are in the same period, and given that we know atomic radius decreases across periods from left to right, we can see that calcium has the largest atomic radius.

A system absorbs 191 kJkJ of heat and the surroundings do 120 kJkJ of work on the system. Part A What is the change in internal energy of the system?

Answers

Answer: the change in internal energy of the system is 311 kJ

Explanation:

Given that;

A system absorbs a heat dQ = 191 kJ

And the the surroundings do work on the system dW = 120 kJ

change in internal energy of the system = ?

We take a look at the first law of thermodynamic

Initially the system absorbs energy ( dQ =1 91 kJ) as heat.

Then the surroundings do work (dW = 120kJ) on the system,

Hence the system gains 120 kJ more.

The total energy change is = heat + work

dU = dQ + dW

dU = 191 + 120

dU = 307 kJ

change in internal energy = 311 kJ

Therefore the change in internal energy of the system is 311 kJ

A gas has a pressure of 645 Torr at 128 ºC. What is the temperature (ºC) of the pressure increases to 824 Torr at constant volume and moles?

Answers

Answer:

512 K

Explanation:

Initial pressure P1 = 645 Torr

Initial Temperature T1 = 128 ºC + 273 = 401 K (Upon converting to kelvin temperature)

Final Pressure P2 = 824 Torr

Final Temperature T2 = ?

The relationship between the variables is given as;

P1 / T1  = P2 / T2

Making T2 subject if formula we have;

T2 = P2T1 / P1

Inserting the values we have;

T2 = 824 * 401 / 645 = 512 K

How many π electrons are there in adenine? State which atoms contribute one electron to the π MOs and which atoms contribute two electrons?

Answers

Answer:

12 π electrons.

Explanation:

The structure of adenine can be seen below.

From the diagram, the total number of electrons in adenine is 70 electrons where 20 of them are core electrons.

Also from this same structure, we will notice that we have a total number of  12 π electrons.

i.e.

Each one of these five atoms described takes part in the π electron. These are N-1, N-3, N-7 which comprise of 2σ bonds, and also each of three N contributes one π electron.

Similarly, N-9 and N-10 contain 3σ bonds; Hence, each of them donates two electrons.

Thus;

5C = 5π electrons

3N = 3π electrons

2N = 4π electrons

     = 12π electrons

The mass of 16.6 × 10²³ molecules of barium nitrate is 718.7g

The number of moles of a substance can be calculated by dividing the mass by its molar mass. That is;

no. of moles = mass(g) ÷ molar mass (g/mol)

no. of moles of Ba(NO3)2 = 16.6 × 10²³ ÷ 6.02 × 10²³

no. of moles = 2.75 × 10⁰

no. of moles = 2.75moles.

Molar mass of Ba(NO3)2 = 261.34g/mol

mass of Ba(NO3)2 = 261.34 × 2.75

Mass of Ba(NO3)2 = 718.7g

Therefore, the mass of 16.6 × 10²³ molecules of barium nitrate is 718.7g.
