b)the zinc strip became thinner
c)the zinc strip became thicker
d)the colour of the zinc strip changed​

Answer 1

Answer:

Explanation:

B is correct answer because copper is less reactive than zinc ,so it is not able to replace zinc from its solution . Hence the copper strip remained as it was. A single replacement reaction is one in which a more reactive element displaces a less reactive element from its salt solution.
