What is the most polar? <br><br> A) C-N <br> B) C-O <br> C) C-C <br> D) C-Cl <br> E) C-F
Nutka1998 [239]
I would say that the most polar is E) C-F, because polarity is proportional to the difference in electronegativity. Since carbon is the same in each molecule, you need to focus on non-carbon atom, which is the most polar.

47.0ml of a HBr solution were titrated with 37.5ml of a 0.215M LiOH solution to reach the equivalence point. what is the molarit
faltersainse [42]

Hello!

The molarity of the HBr solution is 0,172 M.

Why?

The neutralization reaction between LiOH and HBr is the following:

HBr(aq) + LiOH(aq) → LiBr(aq) + H₂O(l)

To solve this exercise, we are going to apply the common titration equation:

M1*V1=M2*V2

M1=\frac{M2*V2}{V1}= \frac{0,215 M * 37,5 mL}{47 mL}=0,172 M

Have a nice day!

N and ca can mix with each othe to make compound-explain
postnew [5]

Answer:

Yes, the formed product is calcium nitride, Ca_3N_2.

Explanation:

Hello,

In this case, the answer is yes, since nitrogen in gaseous state is able to react with calcium in solid state to form calcium nitride as shown below:

N_2+Ca\rightarrow Ca_3N_2

This is possible since calcium losses two electrons and nitrogen gains three electrons to remain positively and negatively charged respectively, forming the aforementioned ionic compound.

Best regards.
