10. What is the atmospheric pressure if the partial pressures of nitrogen, oxygen, and
sashaice [31]

Answer:

1.009 atm is the total pressure for the mixture

Explanation:

To determine the total pressure in atm, of the three gases (N₂, O₂ and Ar) we have to sum all the values.

Sum of partial pressures in a mixture = Total pressure

First of all, we need to convert the values from mmHg to atm

604.5 mmHg . 1atm / 760 mmHg = 0.795 atm

162.8 mmHg . 1atm / 760 mmHg = 0.213 atm

0.500 mmHg . 1atm / 760 mmHg = 6.58×10⁻⁴ atm

Partial pressure N₂ + Partial pressure O₂ + Partial pressure Ar = Total P

0.795 atm + 0.213 atm + 6.58×10⁻⁴ atm = 1.009 atm

Boron has an average atomic mass of 10.81. One isotope of boron has a mass of 10.012938 and a relative abundance of 19.80 percen
Georgia [21]
The average atomic mass is calculated by the expression:

Average atomic mass = Σzₓ(Aₓ)

where zₓ is the relative abundance of an isotope and Aₓ is the atomic mass of the isotope. 

We calculate the mass of the isotope as follows:

10.81 = .1980 (10.012938) + .8020 (x)
x = 11.00 -----------> mass of the isotope

Draw an electron
butalik [34]

Answer:

 . .

: Ne :

  . .

Explanation:

Let's take Neon as our example. In the Lewis dot structure, each dot corresponds to an electron in the valence shell of the atom. All atoms like to have a full valence shell. By the octet rule, this means that they need 8 electrons total to be electronically satisfied. Noble gases all have a full valence shell in their natural state. This is why they are inert, as they do not need extra electrons to be electronically satisfied.
