Answer is: C is equal to 2, D is equal to 6 and E is equal to 1.
C, D and E represent number of electrons on each atomic orbital in sodium atom.
Electron configuration of sodium atom: ₁₁Na 1s² 2s² 2p⁶ 3s¹.
Atomic number of sodium is 11, it means that it has 11 protons and 11 electrons, so atom of sodium is neutral.

<u>Answer:</u> The total number of electrons that must be shared between carbon and oxygen atoms are 8.
<u>Explanation:</u>
A covalent compound is formed when sharing of electrons takes place between the atoms forming a compound.
Carbon is the 6th element of the periodic table having electronic configuration of 
This element requires 4 electrons to complete its shell.
Oxygen is the 8th element of the periodic table having electronic configuration of 
This element requires 2 electrons to complete its shell.
So, in order to complete the octet of both the elements, 2 oxygen atoms are required for 1 carbon atom.
Hence, the total number of electrons that must be shared between carbon and oxygen atoms are 8.
Answer:
296.43 K is the temperature of a vessel when pressure reads 1.250 atm.
Explanation:
At STP, when pressure is 1.000 atm the value of temperature is 273,15 K.
If the pressure at temperature T reads as 1.250 atm.


Applying Gay Lussac's law:
(At constant volume)


296.43 K is the temperature of a vessel when pressure reads 1.250 atm.
