Answer: The partial pressure of H_2 is 737.5 mmHg.

Explanation: According to Dalton's law, the total pressure of a mixture of gases is the sum of individual pressures exerted by the constituent gases.

p_{total}=p_A+p_B

Thus p_{total}=p_{H_2O}+p_{H_2}

Given: p_{total}=755.0mmHg

p_{H_2O}=17.5mmHg

p_{H_2}= ?mmHg

Thus 755.0mmHg=17.5mmHg+p_{H_2}

p_{H_2}=737.5mmHg

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.
