We will do the following steps to solve the problem:
Step 1: Determine limiting reagent
Step 2: Determine the grams of ZnS formed
Step 3: Determine the grams of excess reactant left
Zinc and sulphur react to form zinc sulphide according to the equation.
Zn + S → ZnS
If 25.0 g of zinc and 30.0 g of sulphur are mixed,
a) Which chemical is the limiting reactant?
b) How many grams of ZnS will be formed?
c) How many grams of the excess reactant will remain after the reaction is over?
