in a thermonuclear device, the pressure of 0.050 litters of gas within the bomb casing reaches 4.0 x10^6 atm. when the explosion destroys the bomb casing the gas is released into the atmosphere where it reaches a pressure of 1.00 atm. what is the volume of the gas after the explosion? assume constant temperature and number of moles.
In a seperate trial the student puts 214 mL of the same liquid into the same flask at the same conditions. What will the pressure measure (in kPa) in the second trial?
Show your calculations and determine the half-life of Tc-99 (in hours). (b)The delivery of a sample of Tc-99 from the reactor to the nuclear medicine lab of the hospital takes 3h.
