cnw To CICCIUCremsury ( U 13) Balancing Redox Equations and Stoichiometry 4 of 10 > Review | Constants Periodic Table Redox equations are often long and difficult to balance by inspection. Using oxidation states and half-reactions you can more easily balance a redox reaction. Part A Balance the following equation: K CHO+Na 80s + HCI--KCI + Na, 80+CCI+H2O Generally coefficients of 1 are omitted from balanced chemical equations. When entering your answer, include coefficients of 1 as required for grading purposes. Enter the coefficients for each compound, separated by commas, in the order in which they appear in the equation (e.g., 1,2,,4,5,6,7). View Available Hint(s) Submit - Part B In the process of oxidizing to i, so, is reduced to so. How many moles of so, are produced in the formation of one mole of 1,?

Answer 1

A)Use oxidation method to calculate the coefficients of the redox reaction.

the coefficients are 2,3,10,4,3,2,5.

B) the balanced redox reaction

So 1mole of SO2 is produced in the formation of 1mole of I2.
