A manufacturer of bicycles has 4,815 wheels, 2,305 frames, and 2,225 handlebars.
How many bicycles can be manufactured using these parts?
How many parts of each kind are left over?
Which part limits the production of bicycles?
2NaOH + CO2 → Na2CO3 + H2O
Sodium hydroxide reacts with carbon dioxide to make sodium carbonate and water. Which reactant is limiting when 1.85 mol sodium hydroxide and 1.00 mol carbon dioxide are allowed to react? How many moles of sodium carbonate are produced? How many moles of the excess reactant remain after the reaction is complete?
2Al(OH)3 + 3H2SO4 → Al2(SO4)3 + 3H2O
Aluminum hydroxide reacts with sulfuric acid to make aluminum sulfate and water. Which reactant is limiting when 0.575 mol aluminum hydroxide are placed in a solution containing 0.500 mol sulfuric acid? How many moles of aluminum sulfate form under these conditions? How many moles of the excess reactant remain after the reaction is complete?
Mg(OH)2 + 2HCl → MgCl2 + 2H2O
Identify the limiting reactant when 5.87 g of magnesium hydroxide reacts with 12.84 g of hydrogen chloride to form magnesium chloride and water. What is the theoretical yield of magnesium chloride in grams?
3Ca + 2FeCl3 → 3CaCl2 + 2Fe
Identify the limiting reactant when 11.2 g of calcium metal reacts with 12.1 g of iron(III) chloride to form calcium chloride and iron metal. What is the theoretical yield of iron metal in grams?
C6H6 + Br2 → C6H5Br + HBr
Benzene (C6H6) reacts with elemental bromine to make bromobenzene (C6H5Br) and hydrobromic acid (HBr). What is the theoretical yield of bromobenzene in this reaction when 30.0 g of benzene reacts with 65.0 g of bromine?
8H2S + 4O2 → S8 + 8H2O
Hydrogen sulfide is an impurity in natural gas that must be removed. One common removal method is called the Claus process, which relies on a reaction in which the hydrogen sulfide reacts with oxygen to make elemental sulfur (S8) and water. If you started with 3.00 g of hydrogen sulfide and 50.0 g of oxygen, how many grams of elemental sulfur would be produced?
Zn + 2HCl → H2 + ZnCl2
Zinc and hydrochloric acid react to form hydrogen gas and zinc chloride. How many grams of hydrogen gas would form if you reacted 236 g hydrochloric acid with 257 g zinc?
