A bicycle component manufacturer produces hubs for bike wheels. Two processes are possible for manufacturing, and the parameters of each process are as follows:
Process 1
Process 2
Production rate
35 parts/hour
15 parts/hour
Daily production time
4 hours/day
7 hours/day
Percent of parts
20%
9%
rejected based on
visual inspection
Assume that the daily demand for hubs allows all defect-free hubs to be sold. Additionally, tested or rejected hubs cannot be sold.
Find the process that maximizes profit per day if each part is made from $4 worth of material and can be sold for $30. Both processes are fully automated, and variable overhead cost is charged at the rate of $40 per hour. (2.4)

Predict whether benzoic acid will dissolve in 1.0 M NaOH or 1.0M HCl. Draw the structure of benzoic acid once disolved in your predicted solvent.
Calculate the pH of a 1.3x10^-7 M solution of benzoic acid at 25°C. (The pKa of benzoic acid is 4.19 at 25°C. You may have to take into account the autoionization of water).
