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.
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 - 1. To make a chemical equation more informative, the physical states of the reactants and products are mentioned along with their chemical formulae. 2. The gaseous, liquid, aqueous and solid states of reactants and products are represented by the notations (g), (l), (aq) and (s) respectively. 3. The word aqueous (aq) is written if the reactant or product is present as a solution in water
Answer - Now look at the below Two points for better Understanding. This is because the s p 3 s p X 3 hybridized carbon in the alkyl group is electron donating towards the s p 2 s p X 2 hybridized carbon in the double bond. Electron density likes to flow from low to high s-character orbitals since the more s-character in an orbital, the lower the energy of the electrons in that orbital. As the electrons flow from the s p 3 s p X 3 carbon to the s p 2 s p X 2 carbon the energy of the electrons (and therefore the energy of the molecule) is lowered. A "shorthand" way to illustrate this electron flow is by drawing hyperconjugated resonance structures like the following. Consequently 2-butene (where we can draw 6 hyperconjugated resonance structures) is more stable than 1-butene (where we can only draw 2 hyperconjugated resonance structures). 2) Carbanion stability decreases in the order primary > secondary > tertiary As we've just shown above,...
