Answer the questions given below :-. What is rusting?. What are the necessary things for rusting?. Write steps to prevent rusting?. Write the chemical formula for rusting? |
|
Answer» Answer: 1-Rust is a chemical reaction (oxidation) of iron that OCCURS over a period of TIME as the bare metal surface comes in contact with OXYGEN present in the air or water. Rust "eats" away the metal, rendering it weak and fragile. ... Avoid contact with water or moisture. . 2-Rusting is an oxidation reaction. The iron REACTS with water and oxygen to form hydrated iron(III) oxide, which we see as rust. Iron and steel rust when they come into contact with water and oxygen – both are needed for rusting to occur. . 3- 1.Paint it - Paint the metal with any durable acrylic paint. ... 2.Keep moisture at Bay - Avoid contact with water or moisture. ... 3.Coat it with Oil - Use of oil or grease significantly reduces the chances of developing rust in iron. . 4-Rust is hydrated ferric oxide and its chemical FORMULA is Fe2O3. . . . hope you it is helpful to you. |
