3 days ago · Answer. An acid, as defined by Brønsted and Lowry, is a substance that can lose or donate a proton ( H +) in a reaction. The nitric acid can donate a proton to become a nitrate ion ( N O 3 – ). As the acid is in solution, the water molecules can accept the proton to become hydronium ions ( H O 3 + ):
4 days ago · A metalloid is a type of chemical element which has a preponderance of properties in between, or that are a mixture of, those of metals and nonmetals. There is no standard definition of a metalloid and no complete agreement on which elements are metalloids. Despite the lack of specificity, the term remains in use in the literature of chemistry .
