Stoichiometry and Limiting Factor
12. Given the equation below, what mass of water would be needed to react with 10.0g of sodium oxide?
Na2O + H2O ( 2NaOH
[pic]
13. 2NaClO3 ( 2NaCl + 3O2
What mass of sodium chloride is formed along with 45.0 g of oxygen gas?
[pic]
14. 4NH3 + 5O2 ( 4NO + 6 H2O
What mass of water will be produced when 100.0 g of ammonia is reacted with
excess oxygen?
[pic]
15. If the reaction in #14 is done with 25.0g of each reactant, which would be the
limiting factor?
[pic]
[pic]
Thus, the O2 is the limiting reagent
16. Na2S + 2AgNO3 ( Ag2S + 2NaNO3
If the above reaction is carried out with 50.0g of sodium sulfide and 35.0g of silver
nitrate, which is the limiting factor?
[pic]
