VISUALIZING STOICHIOMETRY - GRAPHS Use the chemical equations and the information provided on the graphs to DRAW AND LABEL BARS to replace the question marks in each of the graphs below. Be sure to write and balance the equation first and use the worksheet as necessary to mathematically determine the missing values. Finally, LABEL THE EXCESS REACTANT AND THE LIMITING REACTANT on the "After" graph.
