Find the moles of sulfur produced, if 2.5 moles of sulfur dioxide are used in the following chemical reaction: SO2 + 2H2S → 2H2O + 3S Select one:
b. 1.25 mol
c. 7.5 mol
d. None of the above
e. 2.50 mol
(A WAS WRONG so I took it out but A is 0.833 mol)

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?

Asample of ammonia reacts with oxygen as shown. 4nh3(g) + 5o2(g) 4no(g) + 6h2o(g) what is the limiting reactant if 4.0 g of nh3 react with 8.0 g of oxygen? o2 because it produces only 0.20 mol of no. nh3 because it produces only 0.20 mol of no. o2 because it produces two times less no than nh3. nh3 because it produces three times more no than o2.
