Explain how the mass % of the KClO3 in your mixture would have been affected had you not heated your sample long enough?
a. The mass of evolved oxygen would be too low, therefore the calculated %KClO3 would be too low.
b. The mass of evolved oxygen would be too low, therefore the calculated %KClO3 would be too high.
c. The mass of residual KCl would be too low, therefore the calculated %KClO3 would be too low.
d. The mass of residual KCl would be too low, therefore the calculated %KClO3 would be too high.
