Vitamin B12 and the Elderly. Vitamin B12 and the elderly is especially important because as we age, our ability to absorb nutrients from food declines. This condition is called atrophic gastritis and is one of the most common causes for vitamin B12 deficiency among the elderly.
Best Answer: A nonelectrolyte is a substance that doesn't split up into ions when dissolved into solution. LiF is an ionic compound that is soluble in water, completely splitting up into ions. HCl is a strong acid, completely splitting up into ions when dissolved in water. Acetic acid is a weak acid. When dissolved in water, a small percentage of it splits into ions, so it still is an electrolyte. Sucrose does NOT split up into ions when dissolved in water so it is a nonelectrolyte.
Best Answer: An example of a gaseous solution is air (oxygen and other gases dissolved in nitrogen). Since interactions between molecules play almost no role, dilute gases form rather trivial solutions.In part of the literature, they are not even classified as solutions, but addressed as mixtures.If the solvent is a liquid, then gases, liquids, and solids can be dissolved.Here are some examples: Gas in liquid: Oxygen in water. Carbon dioxide in water is a less simple example, because the solution is accompanied by a chemical reaction (formation of ions).olid in liquid: Sucrose (table sugar) in water Sodium chloride or any other salt in water forms an electrolyte: When dissolving, salt dissociates into ions. the solvent is a solid, then gases, liquids, and solids can be dissolved.
