Answer:
a= The oxidation state of zinc is changed from 0 to +2 so zinc get oxidized.
b= The oxidation state of H is reduced to +1 to 0. So hydrogen get reduced.
c = The reaction which involve the oxidation reduction are called redox reaction.
The given chemical reaction involve the oxidation of zinc and reduction of hydrogen that's why it is redox reaction.
Explanation:
Oxidation:
Oxidation involve the removal of electrons and oxidation state of atom of an element is increased.
Reduction:
Reduction involve the gain of electron and oxidation number is decreased.
Chemical equation:
Zn + 2H⁺ → Zn²⁺ + H₂
a= The oxidation state of zinc is changed from 0 to +2 so zinc get oxidized.
b= The oxidation state of H is reduced to +1 to 0. So hydrogen get reduced.
Redox reaction:
The reaction which involve the oxidation reduction are called redox reaction.
The given chemical reaction involve the oxidation of zinc and reduction of hydrogen that's why it is redox reaction.

Answer:
Yes, acetic acid could be used, but it would not be as effective as acetyl chloride or acetic anhydride. ... However, the acetic anhydride would still be reacting with an alcohol, so nothing changes in that respect. Also, the reaction would need to be done in basic solution.
C. Cells are made from pre-existing cells. :) Glad I can help
