Answer : The number of moles of sulfur needed to oxidize will be, 3 moles
Solution : Given,
Moles of zinc = 3 moles
The balanced reaction will be,
By the stoichiometry, 1 mole of 
ion react with the 1 mole of 
to give 1 mole of zinc sulfide.
From the balanced reaction, we conclude that
As, 1 mole of zinc react with 1 mole of sulfur
So, 3 moles if zinc react with 3 moles of sulfur
Hence, the number of moles of sulfur needed to oxidize will be, 3 moles
Answer: the statement that is wrong about uncouplers is option A ( they allow ATP synthesis with no electron transport).
Explanation:
An uncoupler is a molecule that disrupts oxidative phosphorylation by dissociating the reactions of ATP synthesis from the electron transport chain. They allow electron transport without ATP synthesis. Their mechanism of action is basically to transport protons back into the matrix, preventing the required buildup of charge on the other side.
2,4-DNP is an example of an uncoupler.

Answer:
A. Metallic bond
Explanation:
Think about it: copper and tin are both common metals. That's how we know it's a metallic bond!
Why not B: Covalent bonds are between two nonmetals.
Why not C: Ionic bonds are between a nonmetal and a metal.
Why not D: Paired bond isn't a common phrase in chemistry.
