Balance the following equation. (for a balanced eq. aA + bB => cC + dD, enter your answer as the integer abcd)


ClO3−(aq) + H2O(l) + I2(s) ® IO3−(aq) + Cl−(aq) + H+(aq)


 
Balance the following equation for a reaction in acidic solution. Only H+ or H2O may be added. (enter your answer as the sum of the coefficients)
