Answer - The chemical reactions in which oxidation and reduction takes place simultaneously are called redox reactions. ‘Red’ stands for reduction and ‘ox’ stands for oxidation
Answer - 1. When oxidation and reduction take place simultaneously in a given chemical reaction, it is called redox reaction or oxidation-reduction. 2. No oxidation can take place without reduction and there is no reduction without oxidation at the same time. 3. When carbon monoxide is passed over heated ferric oxide, carbon monoxide gains oxygen (i.e. gets oxidized) to form carbon dioxide. At the same time, iron oxide gets reduced to metallic iron by the loss of oxygen. 4. Fe 2 O 3 + CO → 2Fe +2CO 2 ↑
Answer - The slow process of decay or distinction ions of a metal due to the effect of air, moisture, acids, alkalies, or other chemicals on it is called corrosion.
