The problem corresponding to the grams of octane that have to be burned to liberate 9.48 × 10 5 kJ of energy is to be classified according to stoichiometry classifications. Concept introduction: Chemical reactions are represented by chemical equations. In a chemical equation, the reactants are represented on the left of the arrow while the products are represented on the right of the arrow. Stoichiometric coefficient is the number preceding each symbol in a reaction which determines the moles of the reactants and products in the reaction. In stoichiometry problems, a known amount of product or reactant is given and the other product or reactant has to be calculated.

Answer 1

Question

Definition Definition Number that is expressed before molecules, ions, and atoms such that it balances out the number of components present on either section of the equation in a chemical reaction. Stoichiometric coefficients can be a fraction or a whole number and are useful in determining the mole ratio among the reactants and products. In any equalized chemical equation, the number of components on either side of the equation will be the same.
