Achemical reaction turns substance a into substance b. the rate at which the reaction takes place is proportional to the square root of the amount of substance a present.
if is the amount of substance a present (measured in grams) at any time (measured in minutes), set up a differential equation for in terms of . if there is an arbitrary constant in your equation, call it and make sure that > 0k> 0.
now, suppose that the chemical reaction is to take place in a large tank of liquid!
the tank contains 25 liters of a solution of substance a dissolved in water. the concentration of the solution is 750 grams per liter. a 200 gram per liter solution of substance a is poured in at 12 liters per minute. at the same time, the solution is drained from the bottom of the tank at 11 liters per minute.
if is the amount of substance a in the tank (measured in grams) at any time (measured in minutes), set up a differential equation for in terms of :

will be high
= 12 (200 grams) - 11/(v(t))a

Lab reagent, hypothesis test. a reference solution used as a lab reagent is purported to have a concentration of 5 mg/dl. six samples are taken from this solution and the following concentrations are recorded: (5.32, 4.88, 5.10, 4.73, 5.15, 4.75) mg/dl. these six measurements are assumed to be an srs of all possible measurements from solution. they are also assumed to have a standard deviation of 0.2, a normal distributin, and a mean concentration equal to the true concentration of the solution. carry out a significance test to determine whether these six measurements provide reliable evidence that the true concentration of the solution is actually not 5 mg/dl.
