Answer:

The amount of CaCO₃ Jeeves needs to find is approximately 71.392 grams

Explanation:

The given parameters are;

The mass of the CaO required = 40 g

The chemical reaction for the production of CaO from CaCO₃ is given as follows;

CaCO₃(s) → CaO(s) + CO₂(g)

Therefore, 1 mole of CaCO₃ produces 1 mole of CaO and 1 mole of CO₂,

The molar mass of CaO = 56.0774 g/mol

Number of moles, n = Mass/(Molar mass)

The number of moles of CaO = 40 g/(56.0774 g/mol) ≈ 0.7133 moles of CaO

Therefore, given that 1 mole of CaO is produced from 1 mole of CaCO₃ 0.7133 moles of CaO will be produced from 0.7133 moles of CaCO₃

The molar mass of CaCO₃ = 100.0869 g/mol

Mass = The number of moles × The molar mass

∴ The mass of CaCO₃ Jeeves needs to find = 0.7133 moles × 100.0869 g/mol ≈ 71.392 g

The mass of CaCO₃ Jeeves needs to find ≈ 71.392 grams.

Answer:

The new volume of the air inside when the cabin is pressurized to 75 kPa is 37818.[tex]\overline 6[/tex] m³

Explanation:

The given 747 airplane parameters are;

The volume of air in the airplane, V₁ = 28,000 m³

The pressure of the air on the ground, P₁ = 101.3 kPa

The pressure of the air once it is in flight, P₂ = 75 kPa

Let V₂ represent the new volume of the air inside when the cabin is pressurized to 75 kPa

Boyle's Law states that the pressure of a given mass of air is inversely proportional to its volume at constant temperature

Therefore, by Boyle's law, we have;

P ∝ 1/V and P₁·V₁ = P₂·V₂

Which gives;

V₂ = P₁·V₁/P₂

Substituting the known values, we get;

V₂ = 101.3 kPa × 28,000 m³/(75 kPa) = 37818.[tex]\overline 6[/tex] m³

The new volume of the air inside when the cabin is pressurized to 75 kPa = V₂ = 37818.[tex]\overline 6[/tex] m³.

Answer:

b. 0.50 moles

Explanation:

To solve this problem we use Avogadro's number (6.023x10²³ atoms/mol).

By dividing the number of atoms (or molecules) by that number, we can calculate how many moles they represent.

So the answer is option b. 0.50 moles.

Answer is : It is a good thermal and electrical conductor. -The main point to be noted is that aluminium is a highly reactive element and still it is used for making cooking utensils. The reason is that aluminium has a very high affinity for oxygen. So, it reacts with oxygen and forms a layer of aluminium oxide on its surface.

Answer:

This is because aluminium reacts with oxygen present in air to form a thin layer of aluminium oxide . This oxide layer is very stable and prevents further reaction of aluminium with oxygen . Also , it is light in weight and a good conductor of heat Hence , it is used to make cooking utensils .

There are 1.4754246675000002e+24 atoms of Hydrogen within the measurement of 2.45 moles of hydrogen!

Explanation:

There are 1.93 x 10²⁴ particles

Given

3.2 moles of Neon gas

Required

Number of particles

Solution

The mole is the number of particles(molecules, atoms, ions) contained in a substance  

1 mol = 6.02.10²³ particles

Can be formulated

N=n x No

N = number of particles

n = mol

No = Avogadro's = 6.02.10²³

So the number of particles for 3.2 moles :

N = 3.2 x 6.02.10²³

N = 1.93 x 10²⁴

or

we can describe it using Avogadro's number conversion factor

Answer:

399.88 [tex]\frac{4.05*10^{23} }{6.022*10^{23} }[/tex] =269

Explanation:

399.88 is the molar mass of iron(III) sulfate.

The mass of 4.05 × [tex]10^{23[/tex] formula units of Fe2(SO4)3 is approximately 6.48 × [tex]10^{25[/tex] grams.

To calculate the molar mass of Fe2(SO4)3, we need to determine the atomic masses of the individual elements involved and multiply them by their respective subscripts:

Fe2(SO4)3 consists of 2 iron atoms, 3 sulfur atoms, and 12 oxygen atoms:

Molar mass of Fe2(SO4)3 = (2 * 55.845) + (3 * 32.06) + (12 * 16.00) = 159.69 g/mol

To calculate the mass of 4.05 × 10^23 formula units of Fe2(SO4)3, we can use the molar mass:

Mass = (4.05 × 10^23) * (159.69 g/mol) = 6.48 × 10^25 g

Rounded to two decimal places, the mass of 4.05 × [tex]10^{23[/tex] formula units of Fe2(SO4)3 is approximately 6.48 × [tex]10^{25[/tex] grams.

Explanation:

In the container with a volume of 893 liters, there are 39.9 moles of air at STP conditions.

We can find the number of moles with the Ideal gas law equation:

[tex] PV = nRT [/tex]

Where:

P: is the pressure = 1 atm (STP)

V: is the volume = 893 L

n: is the number of moles =?

R: is the gas constant = 0.082 L*atm/(K*mol)

T: is the temperature = 273 K

Hence, the number of moles is:

[tex] n = \frac{PV}{RT} = \frac{1 atm*893 L}{0.082 L*atm/(K*mol)*273 K} = 39.9 moles [/tex]

Therefore, there are 39.9 moles in the container.

Answer:

(c) only solute present

Explanation:

In chemistry, the mole fraction, denoted by X, refers to the number of moles of a substance in a compound/mixture divided by the total number of substances in the same compound or mixture.

In this case, we can say that mole fraction represents the number of solutes to the number of solutes and solvent in the solution i.e. X = nA/nA + nB

Where; nA = number of solutes

nB = number of solvent

X = mole fraction.

Based on this analogy, When the mole fraction of solute is 1, there is only solute present. That is; X = 1 / 1 + 0

X = 1/1 = 1.
