Answer:
a)Anode-Zinc
Cathode - Iron
b) At the anode;
Zn(s) -----> Zn^+(aq) + 2e
At the cathode;
Zn^+(aq) + 2e -----> Zn(s)
c) ZnSO4
d) The electrode which is connected to the positive post of the battery is the anode.
The electrode which is connected to the negative post of the battery is the cathode.
Explanation:
Electroplating is an electrolytic process in which a metal is used to cover the surface of another metal. The plating substance is the anode while the plated substance is the cathode. The electrolyte is a salt of the plating metal.
The anode of an electrolytic cell must be maintained at a positive potential with respect to the cathode hence it is connected to the positive terminal of the battery. The cathode must be maintained at a negative potential hence it is connected to the negative terminal of the battery.

1. Causes air to vibrate 2. A hydroelectric dam generating electricity on a river
C I think is the right answer
Answer: Benzene is less reactive than methylbenzoate and more reactive than Nitrobenzene
Explanation:
This is because the methyl group on the benzene ring is an electron donating group leading to the activation of the ring and subsequently leading to more canonical resonance structure at the intermediate stage of the reaction enhancing the faster reactivity
However for the Nitrobenzene the nitro group is an electron withdrawing group leading to a slower activation and less resonance canonical structure at the reaction intermediate leading to a slower reaction than the reaction of benzene without the nitro group
