A student performed an experiment and obtained over 100% yield. What can you most likely conclude from this result? The student's product is pure. The student's product is contaminated. There is no correlation between an experiment and the percent yield. The student must have spilled some reagents. The student performed the experiment exceptionally well.

1) The Law of Conservation of Mass states that the total mass, in an open system, does not change as the result of reactions between its parts. True False 2) The deviation from the theoretical yield to the actual yield is called the percent yield. True False
The actual yield can best be described as the total amount of material involved in a reaction. the amount of reactant left at the end of a reaction. the amount of product recovered at the end of a reaction. the amount of product you could make if a reaction went to completion.
A method for producing pure copper metal involves the reaction of copper(I) sulfide with oxygen gas to give copper metal and sulfur dioxide. Suppose the yield of this reaction is 87%. What mass of a copper ore consisting of 46% copper(I) sulfide must be mined in order to produce 1.0 × 103 kg (1.0 metric ton) of copper metal? Select one: a. 1.5 × 103 kg b. 3.2 × 103 kg c. 1.3 × 103 kg d. 8.0 × 103 kg e. 1.4 × 103 kg
Nitrobenzene (C6H5NO2)(C6H5NO2) is used in small quantities as a flavoring agent or in perfumes, but it can be toxic in large amounts. It is produced by reaction of benzene (C6H6)(C6H6) with nitric acid: C6H6(l)+HNO3(aq) → C6H5NO2(l)+H2O(l The limiting reagent is the reactant that limits the amount of product produced. This is the reactant that produces fewer moles of product when it completely reacts. The reaction involves two reactants, C6H6C6H6 and HNO3HNO3, that react in a 1:1 ratio. You are given the masses of both the reactants, 28.0 gg HNO3HNO3 and 74 gg C6H6C6H6. The molar mass of nitric acid is 63.0 g/molg/mol and that of benzene is 78.1 g/molg/mol. Once you convert 28.0 gg HNO3HNO3 and 74 gg C6H6C6H6 into the number of moles of each using their molar mass, determine which produces less product. Since the coefficients in the balanced chemical equation are all 1, in this specific case you can directly compare the number of moles of each. Calculate the theoretical yield of…
In order to understand how this equation is derived and why it holds true, the product of each side of the equation should be examined. What value and unit do you get when you multiply a concentration of 0.503 M M by a volume of 0.750 L L ? This question can be expressed as 0.750 L1×0.503 molL=0.750 L1×0.503 molL= Express your answer to three significant figures with the appropriate units.
What is a theoretical yield? Actual yield? What are their differences?
What factors during the experiment caused the percent yield to be different than 100%? What impurities may be present in the final product (look at the spectroscopic data for evidence of this), and how does that effect the percent yield calculation? I got 64% for the percent yield.
did i calculate my theoretical yield correctly？
Acrylonitrile is an important building block for synthetic fibers and plastics. Over 2 billion pounds of acrylonitrile are produced in the United States each year. The compound is synthesized from propene in the following reaction:2C3H6 + 2NH3 + 3O2 → 2C3H3N + 6H2OWhat mass of acrylonitrile can be prepared from 150.0 kg of propene, 600.0 kg of ammonia, and 100.0 kg of oxygen?
Platinum is a precious metal that is used as a catalyst for many important industrial reactions. Platinum can be purified by reacting platinum(IV) bromide solution with aluminium metal. To test this purification process, a student reacted 14.4 kg of aluminium metal with excess platinum(IV) bromide solution. After the reaction was complete, the student had extracted 75.4 kg of platinum metal. From this data, calculate the percent error of this experiment.Hint: Write a balanced chemical reaction equation and calculate the theoretical yield of platinum first.Do not show your work in the space provided.Record only your final answer with the correct number of significant digits and the proper units.
Propenoic acid, C3H4O2C3H4O2, is a reactive organic liquid that is used in the manufacturing of plastics, coatings, and adhesives. An unlabeled container is thought to contain this liquid. A 0.257-gg sample is combusted to produce 0.180 gg of water and 0.291 gg of carbon dioxide.
