What was the initial volume of a gas that had an initial temperature of 20.65 C if it reached a final temperature of 41.77 C and final volume of 16.14 L.

Answers

Answer 1

If a gas had an initial temperature od 20.65 C and a final temperature of 41.77 C, its initial volume would be 7.979.

How are volume and example used?

The volume of any solid in three dimensions is equal to the area it occupy. These solids include shapes like a cube, cuboid, conical, cylinder, and sphere. The form affects how much volume there is.

What does a gas' volume mean?

The space occupied by the gaseous particles under typical pressure and temperature circumstances is referred to as the volume of gas. It has the symbol "V." The symbol for volume in the SI is "liters," or "L". When the gas is at normal temperature, a mole has a volume of 24 m3, or 24 000 cm3. The molar volume of a gas is this quantity.

concentrated nitric acid usually has a density of 1.4 g/ml and is 70% hno3 by mass (the rest is water). find the concentration of water in such a solution in mol/l.

Answers

The concentration of water in such a solution in mol/l is 0.0157 M.

Molar concentration is a measure of the concentration of a chemical species, particularly of a solute in an answer, in phrases of quantity of a substance per unit quantity of solution. In chemistry, the most commonly used unit for molarity is the range of moles consistent with liter, having the unit symbol mol/L or mol/dm³ in the SI unit.

Molarity (M) is the quantity of a substance in a certain volume of solution. Molarity is described as the moles of a solute consistent with liters of an answer. Molarity is likewise called the molar attention of a solution.

Calculation:-

The density of the solution is 1.41 g/mL.

1000 g of the solution will have a volume = Mass/ Density

                ​ =  1000 / 1.41

                     =709 ml.

The mass percent of nitric acid is 70%.

1000 g of the solution will have = 1000× 70/100

                                                       =690 g of nitric acid.

The molarity of the solution is  = Mass of nitric acid / The molar mass of nitric acid ×Volume of solution.

does a change in temperature affect the solubility of nh3? if yes, at which temperature would nh3 be most soluble? does pressure change has effect on the solubility of nh3? if yes, at which pressure would nh3 be most soluble?

Answers

Yes as the temperature increases the solubility of NH3 will decrease and as we increase the pressure solubility of NH3  increases.

Solubility is defined as the maximum amount of substance that will dissolve in a given amount of solvent at a given or specified temperature. Based on solubility different types of solutions can be obtained. A saturated solution is a solution where a saturated solution is a solution where a given amount of solute is completely soluble in the solution.

Whereas a supersaturated solution are those where solute starts precipitating out after a certain concentration.

Temperature does effect the solubility of NH3 because as  the temperature increases the hydrogen bonding also decreases, due to which the NH3 molecules are no longer able to bind to water molecules hence their solubility decreases.

But as we increase the pressure on NH3 molecules the bonding with the water molecules will be higher and therefore the solubility also increases.

A typical Heliox mixture contains He at a partial pressure of 0.75 atm and O2 at a partial pressure of 0.35 atm. What is the total pressure of the Heliox mixture?

Answers

Considering the Dalton's partial pressure, the the total pressure of the Heliox mixture is 1.1 atm.

Dalton's partial pressure

Dalton's law states that the total pressure of a gas mixture is equal to the sum of the pressures that each gas would exert if it were alone:

[tex]P_{T}[/tex]= P₁ +P₂ + ... + Pₙ

where n is the amount of gases present in the mixture.

This relationship is due to the assumption that there are no attractive forces between the gases.

Total pressure of the Heliox mixture

In this case, the total pressure of the Heliox mixture is calculated as:

[tex]P_{T} =P_{He} +P_{O_{2} }[/tex]

Being:

[tex]P_{He}[/tex]= 0.75 atm[tex]P_{O_{2} }[/tex]= 0.35 atm

the total pressure of the Heliox mixture is

[tex]P_{T}[/tex]= 0.75 atm + 0.35 atm

[tex]P_{T}[/tex]= 1.1 atm

Finally, the total pressure is 1.1 atm.

What are Ionic compounds ?

Ionic compounds can be defined as ionic bonds or chemical bonds formed by oppositely charged ions held together by electrostatic forces.

These are usually formed between metals and non-metals. Atoms always tend to acquire stable electronic configurations when atoms lose electrons to form cations, and anions are formed when atoms gain electrons. These two oppositely charged atoms together form an ionic bond, which is called an ionic bond.

Ionic compounds, also called ionic compounds, are held together by electrostatic forces. Ionic compounds are also formed when the electronegativity difference between two atoms is large. This causes one atom to attract more electrons than the other, resulting in electron loss and electron gain within the atom.

Verified by Toppr

It is the prior distribution of electrons that constitutes the electrostatic force of interaction..

Explanation:

Commonly, ions are formed by (i) the loss of electrons from metals... electron rich materials from the left of the Periodic Tables as we face the Table, whose valence electrons are furthest removed from the positively charged nuclear core... and (ii) the gain of electrons by non-metals to the right of the Periodic Table as we face it.

We could represent these processes by the reaction...

M→M

n+

+ne

X+e

reduction

We add the two redox processes together in such a way that the electrons are eliminated as virtual particles and we get a neutral salt... of a material and a non-metal that are held together by a strong electrostatic force of attraction...

M+nX→MX

And thus the electrons are formally redistributed to give positive and negative ions that combine to form NEUTRAL SALTS.

Answers

The number of mole of air in the ball, given that the volume of the ball is 5.2 litres is 0.13 mole (Option A)

How to determine the number of mole of air

We'll begin by listing out the given parameters from the question. This is given below:

Pressure (P) = 61 kilopascalsVolume (V) = 5.2 litresTemperature (T) = 32 °C = 32 + 273 = 305 KGas constant (R) = 8.314 L.KPa/Kmol Number of mole (n) =?

From the above parameters, we can obtain the number of mole as follow

PV = nRT

61 × 5.2 = n × 8.314 × 305

317.2 = n × 2535.77

Divide both sides by 2535.77
