Modern definitions of “acid” and “base” (“proton donor” and “proton acceptor”, “producer of cation characteristic of the solvent” and “producer of anion characteristic of the solvent”, “oxide ion donor” and “oxide ion acceptor”, “electron pair acceptor” and “electron-pair ...
In chemistry, an equivalent refers to the amount of a substance that reacts with one mole of another substance. For the purposes of calculating normality, those substances are typically a solute and a solvent.Calculating equivalent unitsrequires looking up the molar mass of the chemicals being use...
All of the alkaline earths react with halogens to form halides. The halides are ionic crystals, except for beryllium chloride, which is acovalent compound. Fun Fact The alkaline earths get their names from their oxides, which were known to humankind long before the pure elements were isolated....
Zinc is a chemical element that is known by the symbol 'Zn.' It has an atomic number of 30, which means that there are 30 protons in its nucleus. Answer and Explanation:1 Chemical properties describe how an element behaves in the presence of other elements or substances. One of zinc's...
What are the properties of ionic bonds? What are the physical properties of covalent compounds? What one characteristic of an atom determines what type of element it is? What determines the chemical properties of an atom? What are the physical and chemical properties of halogens?
Given the electronegativity values of the following atoms, describe the characteristic of the chemical bond formed between them: N (3.0) and another N (3.0) a) nonpolar covalent b) pure covalent c) polar covalent d) ionic e) none of the above ...
