WebMar 25, 2024 · Hydrogen chloride is a colourless gas of strong odour. It condenses at −85 °C (−121 °F) and freezes at −114 °C (−173 °F). The gas is very soluble in water: at 20 °C (68 °F) water will dissolve 477 times its own volume of hydrogen chloride. Because of its great solubility, the gas fumes in moist air.

WebList of chemical elements. This is a list of the 118 chemical elements that have been identified as of 2024. A chemical element, often simply called an element, is a type of atom which has the same number of protons in its atomic nucleus (i.e., … WebExplanation: The periodic table arranges the elements into families and periods (vertical and horizontal rows). The elements in each family have similar properties. As you go across a row, the properties vary gradually from one element to the next. The table tells you what elements may have similar chemical and physical properties.
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. Web3. (Nitric acid) Lewis Structure. HNO 3 (Nitric acid) lewis stricture is drawn step by step by using valence electrons of each element. In the lewis structure of nitric acid, there is a +1 charge on nitrogen atom and one double bond between nitrogen and one oxygen atom.

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. flannel with grey hoodWebYou 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.
