Describe Changes Occurring at the Cellular, Tissue, and or Organ Level That Contributes to the Disease Process osteomyelitis

Phenolphhalein indicator is used in this experiment because it changes color in the pH range of 8.0 to 9.6.

Show by calculation that phenolphthalein is an acceptable indicator for the titration of KHP with NaOH.

This is true if the pH at the equivalence point falls within this range.

In essence, what you need to do is to calculate the pH of the unprotonated phthalate salt. You may assume that the concentration of the salt is approximately 0.05 M at the equivalance point.

HINT: The salt is derived from the weak diprotic acid, which has Ka1 = 1.2 * 10^-3 and Ka2 = 3.9 * 10^-6

A sociologist is interested in the relation between x = number of job changes and y = annual salary (in thousands of dollars) for people living in the Nashville area. A random sample of 10 people employed in Nashville provided the following information.

In this setting we have Σx = 58, Σy = 359, Σx² = 422, Σy² = 13,023, and Σxy = 2160.

Interpretation

For each less job change, the annual salary increases by an amount that falls within the confidence interval.For each additional job change, the annual salary increases by an amount that falls within the confidence interval.    For each additional job change, the annual salary increases by an amount that falls outside the confidence interval.For each less job change, the annual salary increases by an amount that falls outside the confidence interval.

2. Changes in the price of labor will result in both substitution and scale effects that determine what will happen to a firm’s employment of both capital and labor in the long run. Give an example of a production process where you think the substitution effect will most likely dominate the scale effect. In addition, give an example of a production process where you think the scale effect will most likely dominate the substitution effect. Explain your reasoning clearly.

Please give real-life examples that I can use to answer this question
