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.

Balance the following equations. (Use the lowest possible whole number coefficients. Include states-of- matter in your answers.) (a) Mn(s) + O2(g) → Mn2 07 (8) + (b) N₂(g) + O2(g) → N₂O(g) + (c) C10H22 (1) + O2(g) → CO₂(g) + H₂O(1) +

A mixture of O2 (g) and H2 (g) explosively react to form steam H2O (g) in the presence of an electric spark. 4.15 mol of H2 (g) and 7.13 mol of O2 (g) are mixed and allowed to react in the presence of a electric spark. The yield of the reaction is 100%. (a) Write a balanced equation for the reaction. (b) What is the limiting reactant? (answer: 4.15 mol H2 can produce 4.15 mol H2O and 7.13 mol O2 can produce 14.3 mol of H2O, so, H2 is the limiting reactant.) (c) What is the theoretical yield of H2O in moles? (answer: 4.15 mol) (d) How many moles of O2 are left after the reaction? (answer: 5.05 mol) (e) How many moles of H2 and O2 would be left if the reaction yield is only 74.5%? (answer: H2: 1.06 mol left; O2: 5.59 mol)

Consider the following chemical equation: Cu (s) + O2 (g) → Cu2O (s) Is this chemical equation balanced? If not, what coefficient would go in front of the Cu (s) on the reactant side when the equation is balanced? Group of answer choices (a) The equation is not balanced. There would be no coefficient (1) (b) The equation is not balanced. The coefficient would be 3 (c) The equation is balanced (d) The equation is not balanced. The coefficient would be 4 (e) the equation is not balanced. The coefficient would be 2

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.
