A dative bond is a covalent bond, in which all of the shared valence electrons come from the ligand itself. The total number of unique dative bonds formed is the coordination number of the complex. Some ligands can bind to the metal cation using two different donor groups, so we call ...
What is the mass of 2 moles of HgO?HgO:HgO is a two-atom molecule made of mercury and oxygen. This is why it is also called mercy (II) oxide. It has a reddish-orange color. It is often used to produce pure samples of mercury because it decomposes rapidly, releasing the oxygen ...
What is the formula for mass number?Isotopes:Mass numbers are often used to identify the different isotopes of an element. Isotopes are variations in the composition of atoms that belong to the same element. Their elemental affiliation is determined by the number of protons in the nucleus, ...
What is the group number in the periodic table of X, a representative element, in each of the following ionic compounds. 1. X2O3 2. X2SO3 3. Na3X Representative elements: Representative elements involve the filling of s an...
The oxidation number of an atom or ion in a molecule or ion is determined by first finding the sum of the oxidation numbers of other atoms or ions that are attached to it and then equate the sum to the total charge on the ion or molecule....
The numerical subscript specifies the number of atoms existing in the molecule for every element. Answer and Explanation: The given information is that one formula unit of the given ionic compound consists of a total numb...
Solute, combined with the solvent, is a solution. It can be characterized as an aqueous solution if the solvent is water. The salt solution, for example, is an aqueous solution containing salt as a solute and water as a solvent. If the solvent is not water in a solution, it m...
