Alderfer 2 Questions #1 Explain how this method allows you to find the mole ratio of reactants. By finding which ratio of NaClO to KI produces the most heat, we can find which ratio best represents the ratio of moles of the reactants #2 Why must you keep a constant volume of reactants? Since we are trying to find the ratio between the moles of the reactants, we must alter the ratio of one reactant to another. If the volume was changed, the ratio of reactants would also change. #3 Is it necessary that the concentrations of the two solutions be the same? No, if the molarity (concentration) of a solution is known, the total moles of that reactant can be calculated, and it is unnecessary to ensure that the concentrations of the two

Unformatted text preview: solutions are equal. #4 What is meant by the term limiting reagent? The limiting reagent determines how long the reactant can go for. All other reactants will have leftover moles when the reaction stops. #5 Does the measurement of temperature or the measurement of volume limit the precision of your data? Explain. Yes, our equipment was reasonably accurate for our experiment, but did not allow us to achieve pinpoint measurements. However, those kind of measurements would require far more expensive equipment. #6 Which reactant is the limiting reactant along the upward sloping line of your graph? Which i...
