Below are five chemical equations Only one of them is a redox reaction. Identify which equation Is a redox reaction. 1 Calclum carbonatearrow Calclum oxlde+Carbon dloxide 2 Hydrochloric acid+Sodlum hydroxidearrow Sodlum chloride+Wate 3 4 Barium chloride+Sodlum sulfatearrow Barlum sulfate+Sodlum chloride Zinc+Copper(II)sulfatearrow Zinc sulfate+Co 5 Potasslum chloride+Silver nitratearrow Potassium nitrate+Silver chloride Barium chloride+Sodium sulfate-Barium sulfate+Sodium chloride Hydrochloric acid+Sodium hydroxidearrow Sodium chloride+Water Zinc+Copper(II)sulfate-Zincsulfate+Copper Calclum carbonate-Calclumoxise+Carbondioxide Potassium chloride+Silver nitrate - Potassium nitrate + Silver chloride

Answer 1

The correct answer is: 4.

Explanation: A redox reaction involves the transfer of electrons between two species. In the given equations, only equation 4 involves the transfer of electrons, where Zinc (Zn) is oxidized to Zinc sulfate (ZnSO4) and Copper(II) sulfate (CuSO4) is reduced to Copper (Cu).
