When dissolved together, this pair will form a buffer. CH3COOH is a weak acid (acetic acid AKA vinegar) with a Ka=1.8 * 10^ (-5). Ca (CH3COO)2 is calcium acetate, which will dissociate into Ca2+ (a spectator ion as far as the buffer is concerned), and two moles of CH3COO-, the conjugate base of CH3COOH ...
WebDec 22, 2024 · Let's compare sodium, which is the first element in period 3, with argon, the last element in period 3. You could see here that both sodium and argon have a total of three occupied electron shells, following the pattern of elements in the same period.

Since our given value is in grams, we need to convert it to moles. To do this, we will calculate the molar mass (g/mol) of C₂H₅OH using the molar mass of each element found on the periodic table: 2 (12.01g) + 6 (1.008g) + 16.00g = 46.07 g/mol.
WebDec 22, 2024 · Electrons travel from the anode to the cathode. A good way of remembering this is the phrase “ An Ox, Red Cat, ” which tells you that the anode is where oxidation occurs, and the cathode is where reduction occurs.
