Use an ICE Table (Initial-Change-Ending) to analyze a limiting/excess reactant problem.
Consider the balanced chemical equation for the synthesis of hydrochloric acid from its elements:
H2 + Cl2 → 2 HCl
The two reactants are initially mixed in the following amounts:
3.08 moles of H2
2.05 moles of Cl2
Determine the limiting and excess reactants and use this information to complete the cells of the following table. Enter all values as positive values.
