D. Should be correct- the other ones don’t make sense
<span>sulfurs electronic configuration is
1s2 2s2 2p6 3s2 3p4
so for the 3p sublevel
principal quantum no - 3
angulum quantum no - 1
magnetic quantum no - (-1) or 0 or (-1)
spin quantum no - (+1/2) or (-1/2)
so the quantum numbers will be
[ 3 , 1, -1 , +1/2 ] or [ 3 , 1, -1 , -1/2 ]
[ 3 , 1, 0 , +1/2 ] or [ 3 , 1, 0 , -1/2 ]
[ 3 , 1, 1 , +1/2 ] or [ 3 , 1, 1 , -1/2 ]

Hi!
All rocks are connected in a cycle of creation, change, and destruction called the Rock Cycle. The rock cycle begins with molten rock (magma below ground, lava above ground), which cools and hardens to form igneous rock.
Hope this helps!

Answer:
4.8 %
Explanation:
We are asked the concentration in % by mass, given the molarity of the solution and its density.
0.8 molar solution means that we have 0.80 moles of acetic acid in 1 liter of solution. If we convert the moles of acetic acid to grams, and the 1 liter solution to grams, since we are given the density of solution, we will have the values necessary to calculate the % by mass:
MW acetic acid = 60.0 g/mol
mass acetic acid (the solute) = 0.80 mol x 60 g / mol = 48.00 g
mass of solution = 1000 cm³ x 1.010 g/ cm³ (1l= 1000 cm³)
= 1010 g
% (by mass) = 48.00 g/ 1010 g x 100 = 4.8 %
Answer:
C would be the right answer
