1. If 15.5 g of aluminum are reacted with 46.7 g of chlorine gas, then aluminum choride, AlCl3 is formed.
a) which reactant is in excess
b) calculate the number of grams of excess
c)calculate the mass of aluminum chloride produced.
2. In a car battery, lead, lead (IV) oxide, PbO2, and sulfuric acid, H2So4, are reacted to produce lead (II) sulfate, PbSO4, and water.
A)write the balanced equation for the reaction
b) when 10.45 g of lead, 15.66 g of lead (IV) oxide, and 25.55 g of sulfuric acid are mixed, which is the limiting reactant?
c) how many grams of lead (II) sulfate will be produced?
~~~~I need help with on how to do these two problems. if someone explains it,maye i will be able to get the whole chapter. ~~~~~
