Answer: Option (B) is the correct answer.
Explanation:
The given data is as follows.
pH for blood = 7.35,
For carbonic acid,
Therefore, calculate the pH of buffer solution as follows.
pH =
=
Now, putting the given values into the above formula as follows.
pH =
7.35 =
7.35 =
= 9.4
Therefore, we can conclude that the ratio of [bicarbonate]/[carbonic acid] at this pH is 9.4.
B reflecting light because the mirror interacts with the light reflection
Answer:
6
Explanation:
The coordination number of a particular crystal structure arrangement is defined as the number of nearest neighbor atoms or ions surrounding an atom or ion.
We must note that in salts of the type MX, the coordination number of each ion must be equal. The structure of LiCl is built by placing each unit cell next to another such that ions residing in the corner, edge or face sites are shared between adjacent unit cells. The LiCl is in FCC arrangement.
Hence in LiCl, each Li+ ion is surrounded by 6 chloride ions.
The formula of Silver (III) Sulfide is Ag2S3.

Fe is the element Iron, the 2+ is how many electrons is lost to make the ion, so 2 electrons are lost from the valence shell (to make a full outermost shell)
