If the percentage yield is below 100%, what does that mean for your experiment? What possible errors couldhave occurred that resulted in a percentage yield below 100%?

The actual yield of one of the reactions in 43.5g. What was theoretical yield in the laboratory if the scientist concluded that % yield of the reaction ended up to be 77%.

A kf1.amplifire.c SAM P Pearson Learning: Ch 03R: Chemical Reactions and Chemical Quantities QUESTION Stoichiometry is a term chemists use to describe calculations that determine the relative quantities of reactants or products involved in a chemical reaction. Using stoichiometry, chemists can determine the amount of product that can be formed during a chemical reaction from a given amount of reactant. Chemists can also determine the amount of reactant needed to produce a desired amount of product using the same process. Select the missing conversion factor for the following set of calculations. Assume 171 grams of diborane, B,H¸, reacts with excess oxygen, O̟. The problem requires that you determine the mass of boron oxide, B_O¸, formed from this reaction. B,H (9) * 3 O,(9) → B,0 (s) + 3 H,O(I) 1mol B,03 x 27.68 g B,H, 1mol B,H, 1mol B,H, 171g B,H,x. = 4.30 × 10² g B,0, support © 2021 Knowledge Factor, Inc. All rights reserved. МacBook.

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

A 3.82-g sample of magnesium nitride is reacted with 7.73 g of water. M83N2 + 3H20 – 2NH3 + 3MgO The yield of Mgo is 3.99 g. What is the percent yield in the reaction? Atomic weights: Mg=24.31, N=14.01, H=1.01, O=15.99. Input values only with 2 decimal places.

D 0/3 Percent yield of chemical reactions Liquid octane (CH;(CH,) CH,) reacts with gaseous oxygen gas (O,) to produce gaseous carbon dioxide (CO,) and gaseous water (H,0). If 28.5 g of carbon dioxide is produced from the reaction of 11.4 g of octane and 55.6 g of oxygen gas, calculate the percent yield of carbon dioxide. Round your answer to 3 significant figures.

Gaseous methane CH4 reacts with gaseous oxygen gas O2 to produce gaseous carbon dioxide CO2 and gaseous water H2O. What is the theoretical yield of water formed from the reaction of 0.80g of methane and 1.6g of oxygen gas? Be sure your answer has the correct number of significant digits in it.

Suppose 1.0 g of Compound A and 4.0 g of Compound B are consumed in a reaction that produces only one product, Compound C. Calculate the theoretical yield of C. Round your answer to the nearest 0.1 g. Suppose 4.6 g of C are actually isolated at the end of the reaction. What is the percent yield of Compound C? Round your answer to the nearest whole percent. % 0 x10 ロ･ロ X 3. olo
