What is the Combine Gas Law?
Boyle's Law
, Charles Law, and Gay-Lussac Law are combined to form the combined gas law. It claims that a constant exists between the ratio of a gas's absolute temperature to the product of its pressure and volume. The ideal gas law is produced when Avogadro's law is paired with the combined gas law. The combined gas law has no recognized discoverer, unlike the named gas laws. When temperature, pressure, and volume are held constant, the combined gas law is just a combination of the other gas laws that operates. There are a few standard equations for expressing the combined gas law. The established law connects Boyle's law with Charles law as follows:

PV/T = k
We know that,
1 kPa = 0.00987 atm
So,
P = 0.00987*98 = 0.967atm
T= 248K

Now, the ideal gas equation
PV=nRT
again, n= m/M
where,
m= Mass, M =Molar mass
and density(d) = m/v
now, PV= mRT/M
therefore, d = PM/RT
Molar mass of CO2= 44g/mol

Therefore, d = 0.967atm * 44 g/mol / 0.82Latm/Kmol * 248 K = 2.09g/L

suppose that daniel has a 2.50 l bottle that contains a mixture of o2 , n2 , and co2 under a total pressure of 4.80 atm. he knows that the mixture contains 0.230 mol n2 and that the partial pressure of co2 is 0.250 atm. if the temperature is 273 k, what is the partial pressure of o2 ?

Answers

If the mixture contains 0.230 mole N₂ and that the partial pressure of CO₂

is 0.250 atm and if the temperature is 273 k, the partial pressure of O₂ should 2.67 atm.

First we have to find the number of mole of CO₂ :

P = 0.25atm

V = 2.5L

T = 273K

So, find number of moles using:

PV = nRT

0.25 atm × 2.5 L = n × 0.08206 atm.L/ K × 273 K

n = 0.0279 mole

Now, the total mole of gas :

P = 4.8 atm

V = 2.5L

T = 273K

find number of moles using :

PV = nRT

4.8 atm × 2.5 L = n × 0.08206 atm.L/ K × 273 K

n = 0.5357 mole

Now, find mole of O₂ :

mole of O₂ = total mole - mole of CO₂ - mole of N₂

mole of O₂ = 0.5357 - 0.0279 - 0.21

Mole of O₂ = 0.2978 mole

finally, find pressure of O₂ :

V = 2.5 L

n = 0.2978 mole

T = 273K

PV = nRT

P × 2.5 L = 0.2978 × 0.08206 atm.L/ K × 273 K

P = 2.67 atm

So, the partial pressure of O₂ is 2.67 atm.

The number of electrons, protons of neutrons for a particular element in its uncharged state can be found out using its Atomic number( as Z = No. of protons).

For the stability of element the number of electrons and the number of protons present in the atom of an element are equal. While the number of neutrons present in the atom can be found out by subtracting the Atomic number from the atomic mass(as A= no. of neutrons + protons)

To attain the stable valence configuration atoms may loose or attain electrons changing them to a charged ion.

The Atomic no.(Z) of Oxygen is 8, the electronic configuration of Oxygen is

2,6 so Oxygen gains 2 e⁻ to attain the stable valance shell 2,8.

Thus Oxygen a charge of 2⁻.

Then,

The number of protons present in the isotope O⁻² is 8 (Z)

The number of electrons present in the isotope O⁻² is 8 +2 = 10 (Due to the gain of the 2 additional e⁻)

The number of Neutrons present in the isotope O⁻² is A -Z; A= 8

Dehydration can have causes that aren't due to underlying disease. Examples include heat, excessive activity, insufficient fluid consumption, excessive sweating, or medication side effects.

What is dehydration of an alcohol?

One route to the synthesis of alkenes is the dehydration of alcohols. This is the process by which alcohols lose water and form double bonds via E1 or E2 mechanisms. Dehydration reactions of alcohols to form alkenes occur by heating alcohols in the presence of strong acids such as sulfuric acid and phosphoric acid at elevated temperatures.

Alcohol is amphoteric. They act as both acids and bases. The lone pair of electrons on the oxygen atom makes the -OH group weakly basic. Oxygen can donate two electrons to an electron-poor proton. Therefore, in the presence of a strong acid, R-OH acts as a base and is protonated to the strongly acidic alkyloxonium ion +OH 2 (protonated tertiary alcohols have pKas as low as -3.8). I can). This fundamental property of alcohols is essential for dehydration reactions with acids to form alkenes.

Electron configuration is the arrangement of electrons in atomic orbitals. It shows the electrons in numbers, It doesn’t show the details on the spin of electrons like the orbital diagram. Electronic configuration of the Vanadium atom in ascending order of orbital energies,

         1s2 2s2 2p6 3s2 3p6 4s2 3d3

The neutral atom of vanadium is Argon. so, the electronic configuration of vanadium can also be written as,

     [Ar] 3d³ 4s²
