Note: Use the Smaller Amount of Product (SAP) approach for this problem. All remaining conversion steps begin with the SAP amount.Octane (C8H18, MM = 114.23 g/mol) is a component of gasoline. Combustion of octane is represented by the following balanced chemical equation2 C8H18(l) + 25 O2(g) → 16 CO2(g) + 18 H2O(g)If a reaction mixture contains 218 g C8H18 and 455 g O2, (a) Identify the limiting reactant and excess reactant based on the SAP math. [4 points](b) How many grams of CO2 are expected to form? [1 point](c) How many moles of H2O are expected to form? [2 points](d) How many grams of excess reactant are consumed in the reaction?
