Rusting of Iron – Explanation, Chemical Reaction, Prevention
WebSep 12, 2024 · Now, iron has the peculiar property that any fusion or fission reaction involving the iron nucleus is endothermic, meaning that energy is absorbed rather than produced. Hence, nuclear energy cannot be generated in an iron-rich core. Lacking an outward pressure from fusion reactions, the star begins to contract due to gravity. WebEquation of reaction of Ag and hot concentrated HNO 3. Ag + HNO 3 → AgNO 3 + NO 2 + H 2 O. In this reaction, silver is oxidized to +1 oxidation state of silver. Meanwhile nitric acid is reduced to +4 oxidation state (nitrogen dioxide) from +5 oxidation state. During the reaction of Ag and HNO 3, you can observe brown colour nitrogen dioxide ... how many brick can a bricklayer lay in a day
