Delta S reaction= Delta S products- Delta S reactants

don't forget to mulitiply by coefficients

also

here is a really slow way to do it

you know the moles of gas increased

so Delta S is positive

so its B or D

then just do the units digit to see which one match up

At constant temperature and pressure, 5.0 L of SO2 is
Ne4ueva [31]
I've done this a few times and keep coming up with 5.0 L . I used the mole ratio, and SO 2 as the LR. That would make 2 moles of SO3 5.0 L but its not one of your choices. the temp and pressure are constant, so according to n/v = p/rt the volume is the same as the moles. hope this helps

The quantum numbers of six electrons are given bellow .Arrange them in order to increasing energies. (a) n= 4,l =2, m= -2, s= -1
krek1111 [17]

Answer:

e< d< b< c=f< a

Explanation:

Quantum numbers refers to values that exactly describe the energy of electrons within an atom or a molecule. Electrons are known to possess a set of four quantum numbers used in describing the energy state of such electron. These quantum numbers are solutions to the Schrödinger wave equation for the hydrogen atom.

In describing any electron within the atom, the relevant set of four quantum numbers are: principal quantum number (n), orbital, azimuthal, subsidiary or angular momentum quantum number (l), magnetic quantum number (ml), and spin quantum number (ms).

In the arrangement above, the electrons are arranged in order of increasing energy. Each arrangement of quantum numbers corresponds to a particular energy state of the electron.

How many moles are contained in 3.131 × 1024 particles?
Mnenie [13.5K]
One mole contains 6.02×10²³
If x mole contains 3.131×10²⁴

x = 3.131×10²⁴
-------------
6.02×10²³

x = 0.52×10²⁴¯²³

x = 0.52×10¹

x = 5.2moles....

Hope this helped...?
