<span>The notation is not written in the correct order as the 4s subshell should appear before the 3d subshell.
</span>The correct order in an electron configuration would be:
1s , 2s , 2p , 3s , 3p , 4s , 3d , 4p , 5s , 4d , 5p , 6s , 4f , 5d , 6p ,..
So, for germanium the electronic configuration should be;
1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p²
It’s, D. Kinetic Energy.
Explanation: Energy associated with an object’s motion is called kinetic energy. A speeding bullet, a walking person, and electromagnetic radiation like light all have kinetic energy.
Hope this helped ;)
The first thing to do is to convert the mass of sodium
sulfate to moles. Since the given is in milligrams convert it to grams which
would be 0.02824 grams. The number of moles can be calculated by dividing the
converted weight with the given molar mass which is 139.04 g/mol. The number of
mols in the solution is 2.03x10^-4 mols. Then divide the number of moles with
0.02355 L. The molarity of the solution is 0.00862 M.
Answer: 
moles
Explanation:
According to avogadro's law, 1 mole of every substance weighs equal to molecular mass , occupies 22.4 L at STP and contains avogadro's number 
of particles.
To calculate the moles, we use the equation:
Given mass of ethanol = 0.2301
Molar mass of ethanol = 46.07 g/mol
Thus there are moles of ethanol are present in the sample.
