Instructions Use the following BALANCED EQUATION for questions 5-7. Limiting Reactant Calculations Fe2O3 (s) + 3 CO (g) → 2 Fe (s) + 3 CO2 (g) How to Approach a Limiting Reactant Problem: Step 1: Make sure Amounts are in Moles More than one reaction quantity has been provided, One of them is likely the limiting reactant. This must be identified first! If more than one reactant quantity is provided, it is a limiting reactant problem, If they are provided in grams, CONVERT TO MOLES! Step 2: Finding the Limiting Reactant There are different methods of determining the limiting reactant. Regardless of what method is used, the will ALWAYS use the coefficients in the balanced reaction as STOICHIOMETRIC RATIOS in some way. Use your favorite method learned in class or in your book to identify the limiting reactant. Stoichiometry Method Mental Math Method Complete Calculation Method Simple Ratios Method 2 Na(s) + Cl Step 3: Performing Stoichiometric Calculations Based on Limiting Reactant Once the Limiting Reactant has been determined, use it for all future theoretical calculations assuming it has reacted to completion. Use the molar ratios based on the stoichiometric relationships (coefficients) to calculate values like: Theoretical yield of product(s) Amount of the other reactant(s) that reacted Amount of excess reactant that remains. Question at position 7 7 1 point Question at position 7 How many grams of the excess reactant will remain after the limiting reactant is completely consumed? Express your answer in DECIMAL form with TWO significant figures. There should be NO scientific notation and NO units or any symbol other than a number entered in the numeric response question types. Make sure to enter exactly the number of significant figures prompted. no units or scientific notation How many grams of the excess reactant will remain after the limiting reactant is completely consumed? Express your answer in DECIMAL form with TWO significant figures. There sho
