Limiting Reagent Problem I
A factory making bicycles has 866 wheels, 336 handlebars, and 240 bicycle frames in stock. What maximum number of wagons that the factory can make? What parts are left over?
Limiting Reagent Problem II
Ammonia rapidly reacts with hydrogen chloride, making ammonium chloride. Write a balanced chemical equation for the reaction, and calculate the number of grams of excess reactant when 3.0 g of NH3 reacts with 5.0 g of HCl.
Limiting Reagent Problem III
A spark ignited a mixture of 42 grams of oxygen gas and 3.9 grams of hydrogen gas. What is present after the reaction is complete?
2 H2 + O2 ➞ 2 H2O
Limiting Reagent Problem IV
A solution of 80.0 grams of CaCl2 dissolved in 240.2 ml of water is mixed with 347.3 mL of solution that contained 157 grams of dissolved AgNO3. What is the maximum amount of solid product produced?
CaCl2(aq) + 2 AgNO3(aq) ➞ 2 AgCl(s) + Ca(NO3)2(aq)
Limiting Reagent Problem V
A solution containing 12.2 grams of liquid bromine is added to an aqueous solution with 48.7 grams of sodium iodide. What is present after mixing?
Br2(l) + 2NaI(aq) ➞ NaBr(aq) + I2(aq)
