A mother is in with her full-term baby for a 2-week check. She plans to breastfeed full-time for the first 4 months of life and then wean fairly quickly as she returns to work. For now, you would recommend supplementation as follows:

(04.02 MC)  The probability of tails of a weighted coin is 0.58. The number of tails is noted each of the 25 times the coin is tossed. If this procedure is repeated 150 times, what type of distribution is simulated? (3 points)

(05.03 LC) Which pair of compounds has the same empirical formula?

(05.04 LC) Which of the following is an incorrect step to do a complete stoichiometric calculation?

(05.04 MC) The following reaction shows calcium chloride reacting with silver nitrate.CaCl2 + AgNO3 → AgCl + Ca(NO3)2How many grams of AgCl are produced from 30.0 grams of CaCl2?(Molar mass of Ca = 40.078 g/mol, Cl = 35.453 g/mol, O = 15.999 g/mol, Ag = 107.868 g/mol, N = 14.007 g/mol)

K is the chemical symbol for:

(05.02 MC)  A nail fabrication machine makes nails with a target length of μ = 2.35 inches. The machine has some variability, so the standard deviation of the length is σ = 0.2 inch. The machine operator inspects a random sample of 10 nails each hour for quality control purposes and records the sample mean diameter, x̄. Assuming the process is working properly, what are the mean and standard deviation of the sampling distribution of x̄? (4 points)

Physical dependence on a drug is characterized by ________________________.

The position of an object at time t is given by s(t) = -1 – 13t. Find the instantaneous velocity at t = 8 by finding the derivative. (9 points)

(05.06 MC) A chemist reacted 11.50 grams of sodium metal with an excess amount of chlorine gas. The chemical reaction that occurred is shown.Na + Cl2 → NaClIf the percentage yield of the reaction is 85%, what is the actual yield?
