This is the reactant the runs out first and causes the reaction to stop.
limiting reactant
This is the reactant that does not run out.
excess reactant
3 Mg + N2 → Mg3N2
0.3557 moles of Mg are reacted, this is how many grams of Mg3N2 will be produced.
11.97 grams Mg3N2
Cu2O + O2 → 2 CuO
If 15.63 grams of CuO are produced, but the theoretical was 23.95 g of CuO, what is the percent yield of the reaction?
Correct answer is 65.27%
4 Si2H3 + 11 O2 → 8 SiO2 + 6 H2O
4.94 grams of O2 are reacted, how many grams of SiO2 that will be produced.
6.7 grams SiO2
Fe2O3 + 3 H2SO4 → Fe2(SO4)3 + 3 H2O
176.33 grams of Fe2O3 are reacted, this is how many grams of Fe2(SO4)3 will be produced.
441.55 grams Fe2(SO4)3
2 Al + Fe2O3 → 2 Fe + Al2O3
23.32 grams Al to form 30.24 grams of Fe. What is the % yield.
Correct answer is 62.65%
• 100% yield would be 48.27 grams Fe
