3. What do the solubility rules tell you about the way to separate the second group of cations? How can you tell each of the ions in this group apart? Think about changing the temperature and |

the pH. Design your own qualitative schenre for identification of these four Group II ions and

write it below. Experiment with each of the four ions alone and then in combinations. Test an

unknown to see if you can really determine the presence or absence of each of the four ions in

this group

For a science project, a high school research team conducted a survey of local air temperatures. based on the results of the survey, the found that the average temperatures were around 10 degrees higher than expected. this result was wrong. the trouble with the survey was that most of the locations were exposed to direct sunlight and located over asphalt or sand, which resulted in higher temperatures than normal. this is a classic example of an error in which phase of inferential statistics?
