What is named first the cation or anion? correct answer: Cation How many Ligands are in [Cr(NH3)6](NO3)3 correct answer: 6 How many Ligands are in K[Au(OH)4] correct answer: 4 Oxidation number of the metal in K[Au(OH)4]? correct answer: +3 explanation: hydroxide has a charge of -1, since there are a total of 4 hydroxides the total (-) charge is -4. The charge of K is +1. Therefore the charge of Au must be +3. +4 + (-4)=0 Within a complex ion ligands are named in _____________ ord...

What is the principal form of benzoic acid at pH 8.2 if the pKa value is 4.2 correct answer: So, at pH 4.20, there is a 1:1 mixture of benzoic acid (HA) and benzoate ion (A-). At pH = pKa + 1 (= 5.20), the quotient [A-]/[HA] is 10:1. At pKa + 2 (= 6.20), the quotient [A-]/[HA] is 100:1. As pH increases, all the way to pKa + 4 the [A-]/[HA] is 10000:1 *The predominant form of benzoic acid at pH 8 is the benzoate anion For a monoprotic system, the species ___ is the predominant form when ...

Electronegativity A measure of the force of an atom's attraction for the electrons it shares in a chemical bond with another atom -increases from left to right -increases from bottom to top Covalent bond Forms when electron pairs are shared between two atoms whose difference in electronegativity is 1.9 or less Polar covalent bond The more electronegative atom has a partial negative charge, indicated by the 8- The less electronegative atom has a partial positive charge, indicated by the ...
