Answer:
<h2>B</h2>
Explanation:
The proton motive force; is the free energy released during the oxidation of NADH or FADH2 and it is stored both as an electric potential and a proton concentration gradient across the inner membrane.
The purpose of proton motive force is that the movement of protons back across the inner membrane, driven by this force, is used to the synthesis of ATP from ADP and Pi by ATPase/ ATP synthase (F0F1 complex ).
Answer:
The salt is Zn(NO3)2
When the residue is allowed to cool, its colour changes from yellow to white
The equation of the reaction is; 2Zn(NO3)2(s) --->2ZnO(s) + 4NO2(g) + O2(g)
Explanation:
Decomposition of Zn(NO3)2 is one of the routes by which ZnO is obtained. ZnO is a white insoluble powder which has a yellow colour when hot and a white colour when cold. It is an amphoteric substance used as a white pigment in paints and as a filler for rubber.
In a very pure form, it is used in cosmetic powders and creams as well as in medicinal ointments and lotions.
Also recall that NO2 is a brown gas and oxygen gas rekindles a glowing splint.
