Answer:
See explanation
Explanation:
The number of electrons in each principal energy shell increases as the number of shells increases because more electronic orbitals become available to accommodate the electrons.
For instance, the n= 2 level only accommodates eight electrons in the s and p orbitals whereas the n=3 level accommodates 18 electrons in s, p and d orbitals respectively.
Each principal level accommodates 2n^2 electrons where n= the principal energy shell.
i think it's A. cause CH is 1:1 and if you reduce C2H2, the ratio would also be 1:1
Answer:
will have a greater partial charge.
Explanation:
A polar covalent bond is defined as the bond which is formed when there is a low difference of electronegativities between the atoms, thus resulting in charge difference. Example: 
Non-polar covalent bond is defined as the bond which is formed when there is no difference of electronegativities between the atoms and thus there is no charge difference. Example: 
Ionic bond is formed when there is complete transfer of electron from a highly electropositive metal to a highly electronegative non metal. The electronegative difference between the elements is high. The charges on cation and anion neutralise each other. Example: 
Thus as
will have greater partial charge.
Answer:

Explanation:
Hello,
In this case, for the given molarity and volume of such solution, the moles of sodium sulfate are computed below:

Now, by using the Avogadro's number, the ions result:

Best regards.
.......When they yield the same amount , *Reversible reactions* will reach chemical equilibrium........
