1.
Ammonia gas readily combines with hydrogen chloride gas to produce solid ammonium chloride. IF 1.00g of ammonia gas is mixed with 1.00g of hydrogen chlorine gas, determine the limiting reagent and then the mass of ammonium chloride formed
2.
Sodium metal reacts violently with chlorine gas to form sodium chloride.
Determine the limiting reagent and mass of sodium chloride that would be produced from 0.460g of sodium and 0.426 g of chlorine.
3.
If 12.0g of barium nitrate is added to a solution containing 16.0 g of potassium sulfate, how much barium sulfate (in g) is produced? How much of the other product is made?
4.
IF 8.6 g of sodium sulfide is added to a solution containing 10.7 g of silver nitrate, silver sulfide precipitate and aqueous sodium nitrate are formed. What is the limiting reagent? How much silver sulfide will be formed?
5.
Calcium metal burns in oxygen gas to give calcium oxide solid. If 0.48g of calcium is burned in 0.32 g of oxygen, which reagent is in excess? What mass of calcium oxide will be formed?
