Exercise in chemical reaction stoichiometry CHE103 Iron (II) sulfate reacts with sodium hydroxide and sodium nitrate according to the reaction equation: 12 FeSO 4 •7H 2 O + 23 NaOH + NaNO 3 4 Fe 3 O 4 + NH 3 + 12 Na 2 SO 4 + 94 H 2 O Question 1: If 2.50 g FeSO 4 •7H 2 O reacts with the appropriate amounts of sodium hydroxide and sodium nitrate, what is the theoretical yield of Fe 3 O 4 ? Question 2: In a different experiment: if 3.00 g FeSO 4 •7H 2 O is mixed with 0.750 g NaOH and excess NaNO 3 , what is the Limiting Reagent?

Unformatted text preview: What is the Theoretical yield of Fe 3 O 4 , in grams? If it is found that 0.650 g Fe 3 O 4 is produced in this experiment, what is the % yield? Question 3: In a different experiment: in order to get a theoretical yield of 5.00 g Fe 3 O 4 , what weight of NaOH is required, assuming that the other reagents are present in sufficient quantity? Answers: Q1 T.Y. = 0.695 g Fe 3 O 4 Q2 L.R. is NaOH; T.Y. is 0.755 g Fe 3 O 4 ; % yield is 86 % Q3 4.97 g NaOH...
