1. What was the purpose of creating a sodium bicarbonate solution? What was the purpose of adding soap to the solution?
1 answer:
Answer:
1. Source of carbon
2. Removal of cuticle
Explanation:
You may have been doing a photosynthesis lab in a biology course.
1. NaHCO₃
The purpose of creating a sodium bicarbonate solution was to provide the carbon that the plant needs for photosynthesis.
2. Soap solution
The soap solution acted as a detergent. It removed some of the waxy, water-repelling cuticle from the leaf's surface and made it easier for the sodium carbonate solution to get inside.

Explanation:
More is the electronegativity difference between the combining atoms more polar is the compound. Hence, more ionic it will be in nature.
(a) Electronegativity value of P = 2.19
Electronegativity value of Cl = 3.16
Electronegativity value of Br = 2.96
Electronegativity value of F = 3.98
Electronegativity difference of a P-Cl bond = 3.16 - 2.19 = 0.97
Electronegativity difference of a P-Br bond = 2.96 - 2.19 = 0.77
Electronegativity difference of a P-F bond = 3.98 - 2.19 = 1.79
Since, a P-F bond has the highest electronegativity difference. Therefore, is the most ionic compound and
is the least ionic compound.
(b) Electronegativity value of B = 2.04
Electronegativity value of N = 3.04
Electronegativity value of C = 2.55
Electronegativity value of F = 3.98
Electronegativity difference of a B-F bond = 3.98 - 2.04 = 1.94
Electronegativity difference of a N-F bond = 3.04 - 3.98 = 0.94
Electronegativity difference of a C-F bond = 3.98 - 2.55 = 1.43
Since, a B-F bond has the highest electronegativity difference. Therefore, is the most ionic compound and
is the least ionic compound.
(c) Electronegativity value of Se = 2.55
Electronegativity value of Te = 2.1
Electronegativity value of Br = 2.96
Electronegativity value of F = 3.98
Electronegativity difference of a Se-F bond = 3.98 - 2.55 = 1.43
Electronegativity difference of a Te-F bond = 3.98 - 2.1 = 1.88
Electronegativity difference of a Br-F bond = 3.98 - 2.19 = 1.02
Since, a Te-F bond has the highest electronegativity difference. Therefore, is the most ionic compound and
is the least ionic compound.

The tissue cells
Explanation:
I think you mean this
It all starts from Carbondioxide. This Carbondioxide is dissolved in the blood and taken by red blood cell and converted into carbonic acid. It then dissociates to form a bicarbonate ion and a hydrogen ion
This <--> means that the whole process is reversible. It is a buffer system to maintain the pH in the blood and duodenum. And also to support proper metabolic function.
