The pressures given are the partical pressures of the two gases.
The law of Dalton or of the partial pressures states that the total pressure of a mixture of gases is equal to the sum of the pressures of all the gases.
So, in this case:
Total pressure = pressure of nitrogen + pressure of carbon dioxyde.
Of course both terms must be in the same units.
i have found that the pressures for this problem are:
Pressure of nitrogen = 984 torr
Pressure of carbon dioxyde = 345 torr
Total pressure = 984 torr + 345 torr = 1329 torr.
Now convert to atm: 1 atm = 760 torr
=> 1329 torr * 1 atm / 760 torr = 1.74868 atm ≈ 1.75 atm
Answer: 1.75 atm
It is the s-orbital because the order of electrons is s-block, p-block, d-block, and f-block. The p, d, and I think f as well (not 100% about f though) can each hold 8 more valence electrons in their shells.

Pastoral farming is best described as a method of raising livestock and moving herds.
<h3>What is pastoral farming</h3>
Pastoral farming is a system of farming that aims at producing animals rather than crops.
In pastoral farming, the herd of animals are moved from one place to another in search of food and water.
Therefore, pastoral farming is best described as a method of raising livestock and moving herds.

Answer:
The concentration c is equal to Ka
Explanation:
The acid will ionize as observed in the following reaction:
HA = H+ + A-
H+ is the proton of the acid and A- is the conjugate base
. The equation to calculate the Ka is as follows:
Ka = ([H+]*[A -])/[HA]
Initially we have to:
[H+] = 0
[A-] = 0
[HA] = c
During the change we have:
[H+] = +x
[A-] = +x
[HA] = -x
During balance we have:
[H+] = 0 + x
[A-] = 0 + x
[HA] = c - x
Substituting the Ka equation we have:
Ka = ([H+]*[A-])/[HA]
Ka = (x * x)/(c-x)
x^2 + Kax - (c * Ka) = 0
We must find c, having as [H+] = 1/2c. Replacing we have:
(1/2c)^2 + (Ka * 1/2 * c) - (c * Ka) = 0
(c^2)/2 + Ka(c / 2 - c) = 0
(c^2)/2 + (-Ka * c/2) = 0
c^2 -(c*Ka) = 0
c-Ka = 0
Ka = c
