While doing the kinetic trial, Susan forgot to comprise the deionized water. Will this omission hasten or delay the formation of the blue color in the trials Exclusive of Trial 6? Explain.
-Define when doing the kinetic trial Oscar mistakenly omitted the sodium thiosulfae solution. Explain how will this omission change the appearance of the resultant solution from mixing solutions A&B from that of a correctly completed experiment? Explain your reasoning.
- Define when doing the kinetic trial Peyton mistakenly omitted the starch solution from the kinetic trials. Explain how will this omission change the appearance of the resultant solution from mixing solutions A&B from that of a correctly completed experiment? Explain your reasoning.
- Of the three chemists above explain which chemist will have the most accurate results?
