Chemistry In an analysis of the content of carbohydrate present in a glycoprotein, the following results were found: 12.6, 11.9, 13.0, 12.7 and 12.5 g of carbohydrate per 100 g of protein. Taking into account that σ is unknown, the confidence interval for the average value at a 90% confidence level of the carbohydrate content is: Select one:to. 12.5 ± 0.4b. 12.5 ± 0.2c. 12.5 ± 0.5d. 12.5 ± 0.3

Can you show how to out this calculation in the calculator? Everytime I do it, I get a different answer.

3. Consider a solution containing dipolar molecules each having a positively charged head and a negatively charged tail. In the absence of an electric field the molecules point north (n), south (s), east (e), and west (w) with equal probabilities (distribution shown in Fig. 3a). A different probability distribution (shown in Fig. 3b), however, is found when a field is applied to the solution. P P 14 n e น S 7 16 14 16 n e W s Fig. 3a (field absent) Fig. 3b (field present) a) Determine the direction in which the field has its most positive pole (the polarity of the field). b) In the absence of the field, what is the entropy of the system? c) In the presence of the field, what is the entropy of the system? d) Does the application of the field cause the system to become more ordered or disordered?

For example, CHCIBII is chiral, but CCl,BrI is achiral because some of the bonded groups are the same. If a chiral carbon atom is present, then that molecule has a non-superimposable mirror image called an enantiomer. (Figure 1) Part A Identify all the chiral atoms in the below structure by right-clicking* a chiral atom to bring up a menu that includes "Atom Properties."

7. Don believes that fewer than one-third of the students at his college hold part-time jobs while in school. To investigate this, he randomly surveyed 116 students and found that 32 students held part-time jobs. a. ( - Provide a 90% confidence interval for the population proportion of students that hold a part-time job. b. 1 (a). ;Give the correct interpretation of the interval in part c. Extra Credit: Does this interval support Don's claim? Why?

When light hits the AgCl particles, the following reaction occurs: hv AgCl Ag + Cl The silver metal that is formed causes the lenses to darken. The enthalpy change for this reaction is 2.90 × 10² kJ/mol. Assuming all this energy must be supplied by light, what is the maximum vavelength of light that can cause this reaction?
