please someone give me problems based on mole concept and limiting reagent.
Answers
Answer:
Explanation:
Take the reaction: NH3 + O2 NO + H2O. In an experiment, 3.25 g of NH3 are allowed to react with 3.50 g of O2. Hint
a. Which reactant is the limiting reagent?
b. How many grams of NO are formed?
c. How much of the excess reactant remains after the reaction?
If 4.95 g of ethylene (C2H4) are combusted with 3.25 g of oxygen. Hint
a. What is the limiting reagent?
b. How many grams of CO2 are formed?
3)Consider the reaction of C6H6 + Br2 C6H5Br + HBr
a. What is the theoretical yield of C6H5Br if 42.1 g of C6H6 react with 73.0 g of Br2?
b. If the actual yield of C6H5Br is 63.6 g, what is the percent yield?
4)Use the following reaction: C4H9OH + NaBr + H2SO4 C4H9Br + NaHSO4 + H2O If 15.0 g of C4H9OH react with 22.4 g of NaBr and 32.7 g of H2SO4 to yield 17.1 g of C4H9Br, what is the percent yield of this reaction? Hint
5)Silicon nitride (Si3N4) is made by a combining Si and nitrogen gas (N2) at a high temperature. How much (in g) Si is needed to react with an excess of nitrogen gas to prepare 125 g of silicon nitride if the percent yield of the reaction is 95.0%? Hint
Take the reaction: NH3 + O2 NO + H2O. In an experiment, 3.25 g of NH3 are allowed to react with 3.50 g of O2.
