Answer: They are close to each other by 41.03 m^3

Explanation:

From Ideal gas equation, PV = nRT

Where n is negligible

R is gas constant = 8.314 J/mol.k

T = 30 + 273 = 303K

P = 1.02 * 103351.5 = 103351.5 Pascal

Then;

PV = RT

V = P/RT

V = 103351.5/(8.314*303)

V = 41.03m^3

Answer:

See explanation below

Explanation:

This question is incomplete, however, I answered this question on another website, so, I will assume that you need the same answer, cause is the same exercise. If it's not, then please say what's your real question in this exercise.

First of all, you need to know that 1 mole of an ideal gas always occupies 22.4 L. Therefore, using the ideal gas equation, we can solve for the volume that the gas at 1.02 atm occupies, and this will be:

(1 atm x 22.4 L /273 K) x (303 K /1.02 atm ) L = 24.37 L

Converting liter to m³:

24.37 / 1000 = 0.02437 m³

We also know by avogadros number, that 1 mole has  6.02 x 10^23 molecules, and if 1 mole at 1.02 atm has the volume above, then:

0.02437/6.02x10^23 m^3 = 4.05x10^-26 m³

With this result, we can know the length of an edge of the small cube, and we also know that the volume of a cube is a³. We have the volume that the gas occupies, so, we can solve for the length:

l = ∛4x10^-26 m³ = 3.43x10^-9 m

With this, we can compare the distance with the diameter of  a molecule which is 10^-10 m so:

distance = 3.43x10^-9 / 10^-10 = 34.33

This means that is 34 times the diameter of a molecule.

How do sociologists talk about how the individual is related to the larger society?
Viktor [21]

Answer:

Sociologist view that an individual is a reflection of a society to which he or she have belonged.

Explanation:

It is not an individual or a society, but both of them together allows us to reveal the fundamentals of human existence. The extreme view of the person or society has been discarded for quite some time. The concept of society indicates a reciprocal giving-and-take by the individuals involved in the form of mutual corporations, interaction, or the more subtle types of social interaction such as letter writing, festival greeting, sending and accepting presents, telephone communication, e-mailing, internet chatting, and public relations engagement.

What would diluting the vinegar do to the rate of a reaction between vinegar and sodium hydroxide? decrease the rate of reaction
GarryVolchara [31]
Vinegar is aceti acid diluted in water.

The reaction of vinegar with sodium hydroxide is:

CH3COOH + NaOH ---> CH3COONa + H2O

That is an acid-base reaction.

The speed of reaction is proportional to the concentrations of the reactants.

Then, given thatn when you dilute the vinegar you decrease the concentration of CH3COOH, the rate of reaction will decrease.

Answer: decrease the rate of reaction.

How many grams of aluminum is produced when 82.4 grams of aluminum chloride
yKpoI14uk [10]

Answer:

16.6 g of Al are produced in the reaction of 82.4 g of AlCl₃

Explanation:

Let's see the decomposition reaction:

2AlCl₃ →  2Al  + 3Cl₂

2 moles of aluminum chloride decompose to 2 moles of solid Al and 3 moles of chlorine gas.

We determine the moles of salt:

82.4 g . 1mol/ 133.34g = 0.618 moles

Ratio is 2:2. 2 moles of salt, can produce 2 moles of Al

Then, 0.618 moles of salt must produce 0.618 moles of Al.

Let's convert the moles to mass → 0.618 mol . 26.98g /mol = 16.6 g
