When hydrogen sulfide gas is bubbled into a solution of sodium hydroxide, the reaction forms sodium sulfide and water. How many grams of sodium sulfide are formed if 2.00g of hydrogen sulfide is bubbled into a solution containing 2.00g of sodium hydroxide assuming that the sodium sulfide is made in 92.0 % yield?

If 200.0g of copper(ll) sulfate react with an excess of zinc metal, what is the theoretical yield of copper

10-14. (a) when 100.0 ml of weak acid ha were titrated with 0.093 81 m naoh, 27.63 ml were required to reach the equivalence point. find the molarity of ha. (b) what is the formal concentration of a- at the equivalence point? (c) the ph at the equivalence point was 10.99. find pk. for ha. (d) what was the ph when only 19.47 ml of naoh had been added?
