The ideal gas law relates the pressure P , volume V , and temperature T of a fixed number of molecules of a gas in a container via: PV= nRT where R =.082 is constant, using pressure units atm , volume units L , and temperature units K . Suppose there are a fixed amount n =12 moles of oxygen in a container. Determine the rate at which the pressure is changing when the pressure is 4.1 atm and the temperature is 22.5K , if the volume is being decreased by 0.3 L/s and the temperature is being increased by 0.06 K/s.

If anyone has done the algebra 2 chaos theory portfolio would you be wiling to me? i kind of know what i'm doing i just don't know if i'm doing it right.

(round your answer to 2 decimal places.) b. what is the probability that at least one of them will show up? c. what is the probability that neither dave nor mike will show up?
