3. Reaction time experiment (L. Cai, T. Li, Nishant, and A. van der Kouwe, 1996) The experiment was run to compare the effects of auditory and visual cues on speed of response of a human subject. A personal computer was used to present a "stimulus" to a subject, and the reaction time required for the subject to press a key was monitored. The subject was warned that the stimulus was forthcoming by means of an auditory or a visual cue....

Rate is defined as the change in S205 over time. Once the blue color appears, we assume (SOS)-OM, so we have: Initial rate of reaction = "18705) (0-[S,Os initial) (5,05 initial Below are your data for trials 1-6 of Lab 7.

Part 3,4 and 5 please!
Question #1 Rate is defined as the change in [S2052-] over time. Once the blue color appears, we assume [S2052-) = 0 M, so we have: Initial rate of reaction = -d[S205] = -(0-[S205 dt initial) - [S2052 Jinitial time dt Below are your data for trials 1-6 of Lab 7. Enter the initial rate for each trial. [S2052-Jinitial Time Initial rate 2.8x10-5 M/s Trial 1 .00090 M 32 s Ok Trial 2 .00090 M...

can you please answer 5&6?
Four grams (4 g) of NaNO, was dissolved in 10 mL of water and heated to 100°C. Upon cooling, the salt began to recrystallize at approximately 40C. Based on these observations, determine whether sodium or potassium nitrate used in your experiment is the more soluble salt. Explain your answer. pts) We were unable to transcribe this image8. Using the average of your two trials, plot a graph of temperature of saturation of KNO, versus concentration....
