We have to get the maximum number of electrons in an atom that can have the given quantum numbers.
(a) The maximum number of electrons in an atom that can have quantum number n = 5, l = 3, 
= +3 is 2 (two).
(b) The maximum number of electrons in an atom that can have quantum number n = 3, l = 1, = -1 is 2 (two).
Here, n= principal quantum number, l= azimuthal quantum number and = magnetic quantum number.
l= 0 to (n-1) and = -l to +l including 0.
(a) n = 5, l = 3, = +3, this set of quantum number represents one 5f orbital which can contain maximum two electron of opposite spins.
(b) n = 3, l = 1, = -1, this set of quantum number represents one 3p orbital which can contain maximum two electron of opposite spins.
The % yield if 500 g of sulfur trioxide reacted with excess water to produce 575 g of sulfuric acid is calculated using the below formula
% yield = actual yield/ theoretical yield x100
actual yield =575 grams
to calculate theoretical yield
find the moles of SO3 used =mass/molar mass
= 500g/ 80 g/mol =6.25 moles
SO3+H2O=H2SO4
by use of mole ratio of SO3 : H2SO4 which is 1:1 the moles of H2SO4 is also= 6.25 moles
the theoretical yield of H2SO4 is therefore = moles /molar mass
= 6.25 x98= 612.5 grams
%yield is therefore= 575 g/612 g x100= 93.9 %
Answer:
c
Explanation:
sorry if im wrong my apolgies but i think c cus thats the only one that says equal amounts of something
like to test a drop of each so its balanced
Given : Density of Bromine = 3.12 g/mL
Formula : Density = Mass / Volume
Part A :
Given Volume = 125 mL
Density = Mass / Volume
So, Mass = Density x Volume
= 3.12 x 125
= 390 grams
Part B :
Given mass = 85.0 gm
Density = Mass / Volume
So, Volume = Mass / Density
= 85 / 3.12
= 27.24 mL
