In a mixture of 3 gases what is the total pressure of the gases if Gas A exerts a pressure
kirill [66]

Answer:

760 mm of Hg

Explanation:

If the gases A , B and C are non reacting , then according to <u>Dalton's </u><u>Law </u><u>of</u><u> </u><u>Partial </u><u>Pressure</u> the total pressure exerted is equal to sum of individual partial pressure of the gases .

If there are n , number of gases then ,

P_{total}= P_1+P_2+P_3+\dots +P_n

Here ,

  • Partial pressure of Gas A = 400mm of Hg
  • Partial pressure of Gas B = 220 mm of Hg
  • Partial pressure of Gas C = 140mm of Hg

Hence the total pressure exerted is ,

P_{total}= P_{Gas\ A }+P_{Gas\ B }+P_{Gas\ C }

Substitute ,

P_{total}=( 400 + 220 + 140 )mm\ of \ Hg

Add ,

P_{total}= 760\ mm\ of \ Hg

<u>Hence</u><u> the</u><u> </u><u>total</u><u> pressure</u><u> exerted</u><u> by</u><u> the</u><u> </u><u>gases </u><u>is </u><u>7</u><u>6</u><u>0</u><u> </u><u>mm </u><u>of </u><u>Hg</u><u>.</u>

What is the second quantum number of the 3p1 electron in aluminum 1s22s22p63s23p1?
Brut [27]
There are 4 quantum numbers that can be used to describe the space of highest probability an electron resides in.
First quantum number is the principal quantum number- n , states the energy level.
Second quantum number states the angular momentum quantum number - l,
states the subshell and the shape of the orbital
values of l for n energy shells are from 0 to n-1
third is magnetic quantum number - m, which tells the specific orbital.
fourth is spin quantum number - s - gives the spin of the electron in the orbital

here we are asked to find l for 3p1
n = 3
and values of l are 0,1 and 2
for p orbitals , l = 1
therefore second orbital for 3p¹ is 1.
