Chemistry

1. What is the maximum mass of iron that can be obtained by thereaction of 65.25 g Fe2O3 and 25.96 g ofH2?

Fe2O3(s) + 3H2(g)-> 2 Fe(s) + 3H2O(g)

2. What is the percentage yield for a reaction in which 2.50g ofAgCl is obtained from 1.50g of strontium chlorida and a slightexcess of silver nitrate?

SrCl2(aq) + 2AgNO3(aq) ->2AgCl(s) + Sr(NO3)2 (aq)

3. Determine the oxidation numbers for each chemical species.identify the reduced and oxidized chemical species.

2PbO(s) + PbS(s) -> 3Pb(s) +SO2(g)
