Why, in the first part of the experiment, are we using an 8% hydrazine solution in water instead of pure hydrazine? Select the most significant reason below. Hint: Think about how you would assess the hazards of hydrazine when planning an experiment. a - Because hydrazine is highly toxic, a lower concentration of hydrazine is safer to handle. b -Because hydrazine has low molecular weight, the amount of hydrazine used in this reaction will be too small to be measured. c - Because excess water could help prevent a hydrazine explosion from happening under heat. d - Because excess water could increase the rate of reaction between hydrazine and 3-nitrophalic acid
