1.	What is two types of reducing agent used to reduce metal oxide?
Answer» PLEASE READ FULL ANSWER Whenever there is a metal which is oxidising(or rusted or corrosing), it is always affected by air and water. To reduce their OXIDE or to prevent oxiding, these are two different case. CASE 1: Before oxidising- Oil paints and Galvalisation (a process in which a layer of zinc and other non- corrosive metal's layer is PLAYED on SURFACE to AVOID further corrosion). CASE 2: After oxidising- Carbon is one of the best reducing agent to prevent it. Or same materials can also be applied. ****THANK YOU********
