Answer:
It is Though the transfer of charges from one object to another, or (A).
Answer:
D H2PO4– + HPO42–
Explanation:
The acid dissociation constant for
are
respectively.



The reason while option D is the best answer is that, the value of pKa for both
lies on either side of the desired pH of the buffer. This implies that one is slightly over and the other is slightly under.
Using Henderson-Hasselbach equation:

1. 8
2. It's a Noble gas
3. No because it doesn't need any more electrons
4. Physical - odorless yellow inflammable and conductive when it's a plasma
Chemical - unstable

Answer:
Explanation:
The mass percentages of chlorine and fluorine:
Given:
Mass of chlorine = 5.753g
Mass of fluorine = 9.248g
Find the total of the masses given:
Total mass = mass of chlorine + mass of fluorine = 5.753 + 9.248 = 15.001g
% of Cl =
x 100
% of Cl =
x 100 = 38.35%
% of F =
x 100
% of F =
x 100 = 61.65%
<span>The answer is scientific law. This continuously relates in the same circumstances, and suggests that there is a fundamental association connecting its elements. Truthful and well-confirmed statements like "Mercury is liquid at STP" are measured too exact to be suitable as scientific laws. </span>
