WebWhy is iron more soluble in HCL than HNO3. According to the some web resources in the internet, they says using HNO 3 acid can make nitric oxide (NO) gas. Nitric oxide gas can be turned to nitrogen dioxide gas easily. Nitrogen dioxide is a toxic gas. This happnes because nitric acid is an oxidizing acid. But, HCl is not a oxidizng acid. WebNitric acid is composed of three elements. One is hydrogen, and the other two elements are nitrogen and oxygen. The valence electrons of nitric acid are the sum of the total valence … flippin gymnastics
Nitric acid - Wikipedia
2 HNO3 ⇌ [NO2]+ + NO− 3 + H2O Reactions with metals Nitric acid reacts with most metals, but the details depend on the concentration of the acid and the nature of the metal. Dilute nitric acid behaves as a typical acid in its reaction with most metals. Magnesium, manganese, and zinc liberate H2 : Mg + 2 HNO3 → … See more Nitric acid is the inorganic compound with the formula HNO3. It is a highly corrosive mineral acid. The compound is colorless, but older samples tend to be yellow cast due to decomposition into oxides of nitrogen. … See more Commercially available nitric acid is an azeotrope with water at a concentration of 68% HNO3. This solution has a boiling temperature of 120.5 °C (249 °F) at 1 atm. It is known as … See more Nitric acid is made by reaction of nitrogen dioxide (NO2) with water. 4 NO2 + 2 H2O → 2 HNO3 + NO + NO2 + H2O See more Nitric acid is a corrosive acid and a powerful oxidizing agent. The major hazard posed by it is chemical burns, as it carries out acid hydrolysis with proteins (amide) … See more Acid-base properties Nitric acid is normally considered to be a strong acid at ambient temperatures. There is some disagreement over the value of the acid … See more The main industrial use of nitric acid is for the production of fertilizers. Nitric acid is neutralized with ammonia to give ammonium nitrate. This application consumes 75–80% … See more The discovery of mineral acids such as nitric acid is generally believed to go back to 13th-century European alchemy. It has sometimes been claimed that nitric acid occurs in various … See more WebYou need twice as much H2 as CO since their stoichiometric ratio is 1:2. So 12.7 mols of CO would require twice the amount of mols of H2, or 25.4 mols of H2. If you wanted to use up the entire 32.2 mol supply of H2, you would need 1/2 of the 32.2 mols for the required mols of CO, or 16.1 mols of CO. WebNov 18, 2024 · The chemical formula of an element is a statement of the composition of its molecule in which symbol tells us the element and the subscript tells us how many atoms are present in one molecule. One molecule of hydrogen element contains two atoms of hydrogen, therefore, the formula of hydrogen is H 2. greatest theologians
