Calculate the hydrogen-ion concentration [H+] for an aqueous solution in which the hydroxide-ion concentration [OH-] is 1 x 10^-10 mol/L. Is this solution acidic, basic or neutral? Please show work. If the solubility of a gas is 8.4 g/L at 404 kPa pressure, what is the solubility of the gas when the pressure is 101 kPa? Please show work

Find the slope of the line that contains the following points. r(-2, 4), s(6, -2)

For what values of x is x2 + 2x = 24 true?

Amachine that produces a special type of transistor (a component of computers) has a 2% defective rate. the production is considered a random process where each transistor is independent of the others. (a) what is the probability that the 10th transistor produced is the first with a defect? (b) what is the probability that the machine produces no defective transistors in a batch of 100? (c) on average, how many transistors would you expect to be produced before the first with a defect? what is the standard deviation? (d) another machine that also produces transistors has a 5% defective rate where each transistor is produced independent of the others. on average how many transistors would you expect to be produced with this machine before the first with a defect? what is the standard deviation? (e) based on your answers to parts (c) and (d), how does increasing the probability of an event a↵ect the mean and standard deviation of the wait time until success?
