Answer:
I think non-polar although not 100% sure
hope this helps X3
> How many valence electrons does a helium atom have?
The electron configuration of Helium is simply 1s2. We see
that its outermost shell is the s shell and it contains 2 electrons, therefore
the number of valence electrons is also 2.
> What is the formula of the ion formed when potassium
achieves noble-gas electron configuration?
Potassium has a electron configuration of [Ar] 4s1. To
have an electron configuration of only [Ar] which is a noble gas, the one electron
from 4s1 should be removed, hence:

Answer : The expression for reaction quotient will be :
![Q_c=\frac{[Zn^{2+}]}{[Ag^{+}]^2}](https://tex.z-dn.net/?f=Q_c%3D%5Cfrac%7B%5BZn%5E%7B2%2B%7D%5D%7D%7B%5BAg%5E%7B%2B%7D%5D%5E2%7D)
Explanation :
Reaction quotient (Qc) : It is defined as the measurement of the relative amounts of products and reactants present during a reaction at a particular time.
The given redox reaction is :
In this expression, only gaseous or aqueous states are includes and pure liquid or solid states are omitted.
The expression for reaction quotient will be :
The specific proteins produced by cell B in response to the foreign substance are antibodies.
<h3>What are antibodies?</h3>
Antibodies are specific proteins produced by the immune cells of the body in response to a foreign substance called antigen which produces the immune response.
Antibodies are released by immune cells such as B cells.
The antibodies bind to antigen and tag them for destruction by phagocytes.
Therefore, cell B will produce antibodies.
