Answer: The Avogadro number = 6.022\times 10^{23}.

Explanation:

Avogadro number is defined as number of atoms or molecules or particles in one mole of the substance. It is denoted by symbol N_A

N_A=6.022\times 10^{23} atoms or molecules or particles

This constant number is given by an Italian scientist Amedeo Avogadro in 19th century.

The Avogadro`s number is 6.022 × 10 ^ 23 or 6.0221409 × 10^23 
Avogadro`s number is the number of units in one mole of any substance :)))

A container is filled with a mixture of helium, Xenon, and neon gases. The total pressure inside the container is 1,788 mmHg. If
dmitriy555 [2]

Answer: The partial pressure of Xenon in a container filled with a mixture of helium, Xenon, and neon gases and a total pressure inside the container is 1,788 mmHg with the pressure of the helium gas as 760 mmHg, the pressure of the neon gas as 200 mmHg is 828 mmHg

Explanation:

NOTE :

Dalton's law of partial pressures states that in a mixture of gases the pressure exerted by each gas is the same as that which it would exert if it alone occupied the container.

How to determine the partial pressure

Total pressure = Partial pressure of Neon + Partial pressure of Xenon + Partial pressure of helium

Partial pressure of Xenon = ? mmHg

Partial pressure of Helium = 760 mmHg

Partial pressure of Neon = 200 mmHg

Total pressure of gases = 1, 788 mmHg

Partial pressure of Xenon = Total pressure - Partial pressure of Helium - Partial pressure of Neon

Partial pressure of Xenon = 1, 788 - 760 -200

Partial pressure of Xenon = 1,788 - 960

                                           = 828 mmHg

Thus, the partial pressure of Xenon is 828 mmHg

Element A has seven valence electrons. How does its reactivity compare to that of element B, which has four valence electrons?
nignag [31]

Element A is more reactive. Take Fluorine for example. Since its in group 17, it needs one more electron to have an octet. Compared with carbon, group 14 with 4 valence electrons, Fluorine wants and is able to get an electron much more easily.

sertanlavr [38]

Answer:

76.5g is present in 2.55mol of diazine

Explanation:

no. of mole equals mass over molar mass

molar mass of diazine equals 30g/mol.. then substitute to get the mass in grams which is 76.5g
