    hi why would it be rubidium chlorate +7 and not +9?

      @TutorDavidSJ  Месяц назад +1

      The oxidation of rubidium is +1 and the oxidation for oxygen is -2 (but because there are 4 oxygens the total oxidation is -8); we are finding the oxidation of chlorine which is donated by x. RbClO3 is overall 0. Therefore the equation can be written as:
      +1 + x + (-8) = 0
      X = 8-1
      X = 7
