(c) write the chemical equation.​

Answer 1

Answer:

write the chemical equation.suppose you take a copper sulphate solution in a beaker and drop a clear iron nail into it and leave it for about an hour.

(a) what changes will you to observe?

(b) Are these changes are a chemical change? if yes how?

(c) write the chemical equation.

Answer 2

Answer:

a) From the given statement, expected changes are given below:

i) Colour turns from blue to green.

ii) A brown colour is found to be deposited on iron nail surface.

b) Yes, the nature of these changes are chemical. The reason behind this is 'iron sulphate' and copper are produced in the reaction.

c) The reaction is:

Copper sulphate(Blue)+Iron(Shining white)→Iron sulphate(Green)+Copper(Brown).
