1. What is the maximum mass of iron that can be obtained by thereaction of 65.25 g Fe₂O₃ and 25.96 g ofH₂?
Fe₂O_3(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?
SrCl_2(aq) + 2AgNO_3(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) +SO_2(g)
