Top answer
Fe(s) + CuSO4 ⟶ Cu(s) + FeSO4 When an iron nail is dipped in copper sulphate solution, a brown coating of copper is formed on the surface of iron .
Answer: when we heat feso4 it decompose into fe2o3 , so2 , and so3
so the x compound formed is fe2o3 and the gas y formed is so2 and the gas z formed is so3
Explanation:
the color od compound x that is fe203 is brownish red that is also the basically rust , and the common element is oxides of sulphur
---- > when iron nail kept in cuso4 solution the highly reactive metal iron displace copper and makes feso4 and the iron nail become brown in color due to copper presence
