A chemist is designing an experiment to investigate the effect of temperature on the rate of a chemical change. Suggestion a suitable hypothesis for the experiment. Also, list dependent, independent, and controlled variable that can exist in such an investigation.

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.

the dissolution of polymer can be thermodynamically described in 2 steps.
