That decreases its MnO_4^(2-) +4H_2O + 2S^(2-) =2 S+ Mn^(2+) + 8 OH^- Mn reduceds itself from N° of oxidation +6 to +2 buying 4 electrons. To balance the semireaction i write 8 OH^- on the right because the reaction happen in basic environment, and because i must balanced the 6 negative charges on the left MnO_4^(2-) + 4 e^(-)+4H_2O = Mn^(2+) + 8 OH^- S oxidizes itself from -2 to 0 S^(2-) = S+ 2 e^- multiplying On the product side the Carbonic Acid (#H_2CO_3#) is the Conjugate Acid as it is the hydrogen donor to the Conjugate Base (#OH^-#) as it receives the hydrogen ion. You started with "0.

Regardless, what matters for neutralization is what amount of "NaOH" you add to what number of mols of "HCl". 3072 g" We want the standard enthalpy of formation for Ca (OH)_2. 45 M" = "n"/"0. color (white) (mmmmmmmm)"HF" + "H"_2"O" ⇌ "H The balanced chemical equation for the partial dissociation of the base looks like this "BOH"_text ( (aq]) rightleftharpoons "B"_text ( (aq])^ (+) + "OH"_text ( (aq])^ (-) By definition, K_b will be equal to K_b = ( ["B"^ (+)] * ["OH"^ (-)])/ ( ["BOH"]) Rearrange this to get K_b/ ( ["OH"^ (-)]) = ( ["B"^ (+)])/ ( ["BOH"]) color (blue) ( ( ["BOH The added water to reach "100.
