7) Hydrogen gas and bromine gas react to form hydrogen bromide gas.
a. Write a balanced chemical equation for this reaction.
b. 3.2 g of hydrogen gas and 9.5 g of bromine gas react. Which is the limiting
reagent?
c. How many grams of hydrogen bromide gas can be produced using the amounts in
(b)?
d. How many grams of the excess reactant is left unreacted?
e. What volume of HBr, measured at STP, is produced in (b)?
8) When ammonia gas, oxygen gas and methane gas (CH
) are combined, the products
4
are hydrogen cyanide gas and water.
a. Write a balanced chemical equation for this reaction.
b. Calculate the mass of each product produced when 225 g of oxygen gas is reacted
with an excess of the other two reactants.
c. If the actual yield of the experiment in (b) is 105 g of HCN, calculate the percent
yield.
9) When solutions of potassium iodide and lead (II) nitrate are combined, the products
are potassium nitrate and lead (II) iodide.
a. Write a balanced equation for this reaction, including (aq) and (s).
b. Calculate the mass of precipitate produced when 50.0mL of 0.45M potassium
iodide solution and 75mL of 0.55M lead (II) nitrate solution are mixed.
c. Calculate the volume of 0.50M potassium iodide required to react completely with
50.0mL of 0.50M lead (II) nitrate.
