Calculating the Amount of Product Formed from a Limiting Reactant
2 H2(g) + O2(g)→2 H2O(g)
isused to produce electricity in a hydrogen fuel cell. Suppose a fuel cell contains 150 g of H2(g) and 1500 g of O2(g) (each measured to two significant figures). How many grams of water can form?
When a 2.00-g strip of zinc metal is placed in an aqueous solution containing 2.50 g of silver nitrate, the reaction is
Zn(s) + 2 AgNO3(aq)→2 Ag(s) + Zn(NO3)2(aq)
(a) Which reactant is limiting?
(b) How many grams of Ag form?
(c) How many grams of Zn(NO3)2 form?
(d) How many grams of the excess reactant are left at the end of the reaction?
