Answer:
The ice chunk will take 2.47 seconds to hit the water.
Explanation:
Height from which ice chunk fell = h = 30.0 m
Initial velocity of the ice chunk = u = 0 m/s
Time taken by ice chunk to cover 30.0 m of height = t
Acceleration due to gravity = g 
Using second equation of motion ;



The ice chunk will take 2.47 seconds to hit the water.
Answer:

Answer: Reduced
Explanation: Oxidation reaction is defined as the reaction in which a substance looses its electron. The oxidation state of the substance gets increased.

Reduction reaction is defined as the reaction in which a substance gains electrons. The oxidation state of the substance gets reduced.

Given :
Thus as in the given reaction the oxidation state of the metal has decreased from 0 to-1, it is getting reduced.
