When the acid is hydrolyzed, the reaction is
HA --> H⁺ + A⁻
So,
Ka = [H⁺][A⁻]/[HA]
Apply the ICE approach:
HA --> H⁺ + A⁻
I 0.3 0 0
C -X +X +X
E 0.3-X X X
Ka = [X][X]/[0.3-X]
X = H⁺ = A⁻
The formula for pH is:
pH = -log[X]
5.2 = -log[X]
Solving for X,
X = 6.31*10⁻⁶
Therefore,
Ka = [6.31*10⁻⁶][6.31*10⁻⁶]/[0.3-6.31*10⁻⁶]
<span>Ka = 1.33×10⁻¹⁰</span>
Covalent bonds do not involve electron transfer because in covalent bonds, the electrons are shared between the atoms to form the molecule rather than being transferred to form ions as it is in the case of ionic bonds.<span />
Answer:
The description of that same scenario is listed mostly in the explanation portion following.
Explanation:
This same respiratory system involves several lungs, as well as the systemic circulation concerning this same human heart, which operates in conjunction to pick up more oxygen as well as expel CO2 from the body.
- These same lungs encourage O2 to pass both through alveoli via the blood capillaries surrounding off the front of the alveoli, that are otherwise interconnected to the arterial circulation, which carries O2 rich blood something to human heart through which O2 rich blood was indeed transported to many other blood vessels via the artery
- Consequently, those system works together to promote the transmission of gas throughout tissues and organs and also to ensure sustainable the tissue functions required during metabolic functions.
