2. the main goal of donders’s reaction time experiments was to: a. show that cognitions are often based on unconscious inferences. b. determine differences in the way people react to stimuli. c. demonstrate that reaction times can be measured accurately. d. measure the amount of time it takes to make a decision.

Chemical energy is a form of a. kinetic energy only. b. both potential and kinetic energy. c. neither potential nor kinetic energy. d. potential energy only. reset

Given the data below for the reaction, 2 a + 2 b + 4 c => d + e + 3 f, the reaction is fill in the [ ] order in a, fill in the [ ] order in b, fill in the [ ] order in c and fill in the [ ] order overall.

If you are told to get 100 ml of stock solution to use to prepare smaller size sample for an experiment, which piece of glassware would you use?
