Identifying the limiting reactant in a drawing of a mixture

Consider the reaction. 2 Pb(s) + O₂(g) - 2 PbO (s) An excess of oxygen reacts with 451.4 g of lead, forming 361.0 g of lead(II) oxide. Calculate the percent yield of the reaction. percent yield:

. Consider a 3.52-g sample of CaCO3 (99.87% pure) in a flask and a 100.0 mL sample of vinegar (5% acidity) in a graduated cylinder. The combined mass of both reagents and containers is 255.98 g. After swirling the reaction mixture for about twenty minutes, the combined mass of the reaction mixture and containers is found to be 254.46 g. What is the percent yield of carbon dioxide in this experiment?

16) A sample of nitrogen gas reacts with an excess of hydrogen gas to give an actual yield of 23.7 g NH3.  The theoretical yield is 25.3 g.  What is the percent yield for this reaction?                                                      N2(g)   +   3 H2 (g)    →   2 NH3 (g)

Upon reaction of 1.27 gof copper sulfate with excess zinc metal, 0.239 g copper metal was obtained as an experimental result according to the equation: CuSOalaq) + Zn(s) Culs) + ZnSO.laq) Before the experiment was carried out the theoretical yield calculation was completed to predict the maximum amount of copper that could be isolated. The answer was 0.506 g of Cu. What is the percent yield in standard notation?

A 1.897 g sample of pure Mg(HCO3)2 was heated and decomposed. When the sample cooled, it weighed 1.071g. What is the percent yield of this reaction?
