Answer:
C. Hb binds O2 more tightly than Mb.
Explanation:
<u>Hb and Mb are both oxygen carrier protiens which contain the heme group. Hb has 4 heme units in 1 moleucle which work via coperative effect. On the other hand, Mb has only one heme unit. </u>
<u>From above theory, statement A and B are correct.</u>
<u>Although the heme group of the Mb is identical to those of Hb, Mb has a higher affinity for carrying oxygen than hemoglobin.</u>
<u>Hence, Statement C is wrong.</u>
Thats why the function of hemoglobin is to transport oxygen and that of myoglobin is to store oxygen.
<u>When a curve is plotted between oxygen accepted and the pressure of the oxygen, Hb shows sigmoidal, whereas Mb shows hyperbolic oxygen saturation curves.</u><u> The statement D is correct.</u>
<u>Bohr effect and various factors decribe the statement : Hb-oxygen binding is dependent on physiological changes in pH, whereas Mb-oxygen binding is not. </u><u>The statement E is also correct.</u>
Answer:
[Cl₂] = 0.1804M
Explanation:
The reaction of Si with Cl₂ is:
Si(s) + 2Cl₂(g) ⇄ SiCl₄(g)
Where equilibrium constant, k, is:
k = 0.30 = [SiCl₄] / [Cl₂]²
<em>Si(s) is not in the equilibrium reaction because pure solids don't take part in the equilibrium.</em>
As initial concentration of SiCl₄ is 0.10mol / 1L = 0.10M, when the equilibrium is established, concentrations are:
[SiCl₄] = 0.10M - X
[Cl₂] = 2X
<em>Where X is the reaction coordinate.</em>
Replacing in k equation:
0.30 = [0.10-X] / [2X]²
0.30 = [0.10-X] / 4X²
1.2X² = 0.10 - X
1.2X² + X - 0.10 = 0
<em>Solving for X:</em>
X = - 0.92M → <em>False solution. There is no negative concentrations.</em>
X = 0.0902M → Right solution.
[Cl₂] = 2×0.0902M = 0.1804M
<h3> [Cl₂] = 0.1804M</h3>
