Answer:
electrons fill lower energy levels first before occupying higher energy levels.
Explanation:
The Aufbau's principle describes that electrons fill lower energy levels first before occupying higher energy levels.
In writing the electronic configuration of atoms, the Aufbau's principle is one of the most important principles to consider.
It states that "sublevels with with lower energies are filled up before those with higher energies".
Sublevels do not fill up in numerical order.
preferAnswer:
The octet rule refers to the tendency of atoms to prefer to have eight electrons in the valence shell. When atoms have fewer than eight electrons, they tend to react and form more stable compounds. Atoms will react to get in the most stable state possible

Answer:
2 oz. just multiply 56.8 with 0.03527
Explanation:
Potassium Chloride = KCl
KCl has a molar mass of: 39.0983g+35.4530g=74.5513g
The number of moles of KCL we are adding is:
2g/(74.5513g/mol) = 0.02683 mol
But you have to keep in mind that salts in
water dissociate:
KCl -> K+ + Cl-
So 1 mole KCl is 2 osmoles (because it’s
two particles)
So if you add 0.02683 moles, you are adding
0.02683*2 = 0.05366 osmoles.
If you dissolve them in 1 liter, you have a solution 0.05366 OsM = 53.66 mOsM
D5W = dextrose 260 mOsM
1/2 Normal Saline =
has half of the normal saline concentration - a normal saline solution has the
same sodium chloride concentration as blood serum = 154 mOsm
You have to sum up all the osmolarities:
<span>= </span>53.66 mOsM + 154 mOsM + 260 mOsM = 467.66 mOsM
