To test a spectrophotometer’s accuracy, a solution of 60.06 ppm K2Cr2O7 is prepared and analyzed. This solution has an expected absorbance of 0.641 at 350.0 nm. Several aliquots of the solution produce the following absorbance values.   0.640    0.638    0.640    0.639    0.640    0.639    0.638  is there any significant difference between the experimental mean and the expected value at a 99.9% confidence level?   Question 21 options:   Yes because tcal<tcritical   Yes because tcal>tcritical   No because tcal<tcritical   No because tcal>tcritical

4) Which direction is favored when dissolved in acetone? Does the answer change if dissolved in methanol? Explain. Nal ce

Organic Chemistry 1 Why did you choose your choice? Explain your reasoning and rational (theory and principles and periodic trends) as to why the species is the strongest base or the strongest conjugate acid. That is to say, provide a reasoning and an answer to your selection/choice. Why did you circle your answer for that particular species?

Please correct these within the same method provided. no stick form i dont like those. i attached the example i dont NOT WANT IT. SO PLEASE DONT USE IT.
