When 0.050 mol of hydrochloric acid is mixed with 0.050 mol of sodium hydroxide in a calorimeter, the temperature of 1.00 x 10^2 g of the resulting solution increases from 25.0 degrees Celsius to 31.5 degrees Celsius. Specific heat is 1.00 cal/(g x degrees Celsius). Calculate the temperature change that would have been observed if 50.0 g of solution were in the calorimeter instead of 1.00 x 10^2 g of solution. (This is a practice problem in my college textbook, it is not assigned just there to help understand the concepts. Unfortunately, it is very confusing. I do not cheat.)

Problem #2.A 35-year-old male came to the ER.History and Physical Examination:History: Two days ago, the patient felt mild pain around the right ear. He got up in the morning and felt weakness along the right face, and upon looking in the mirror, he found his face pulled towards the left side.Physical Examination: The ER physician asked him to close his mouth and fill it with air; he could not close the mouth; the right corner sags down, and the air leaks out. The patient also complained of difficulty in drinking (the water drooled out) and speaking.When asked to close his eyes, the patient cannot fully close his right eye; the right lower eyelid is drooped down. The patient complains of a change in the taste of food.Q3.

Suppose you are the owner of a truck business. You employ 3 drivers who can travel 500 miles a day; their job is to simply drive the trucks from one place to another, i.e. they do not load or unload the cargo. Your business brings in $1,000 in profit every day; that is, the money you keep after including direct costs like fuel, wages, and insurance.
