The pressure inside a hydrogen-filled container was 2.10 atm at 21 C . What would the pressure be if the container was heated to 85 C ? Express your answer numerically in atmospheres.
Suppose you have a mixture of 2 substances. You know one of the substances is either 2-chlorobenzoic acid or diphenyl acetic acid. The second substance is either p-dibromobenzene or acenaphthylene
Five kg of water initially a saturated vapor at 100kPa are cooled to saturated liquid while the pressure is maintained constant. Sketch the process on a p-v diagram
A fixed quantity of gas at 21 exhibits a pressure of 730 and occupies a volume of 4.40. Use Boyle's law to calculate the volume the gas will occupy if the pressure is increased to 1.85 while the temperature is held constant.
What is the activity coefficient of H in a solution containing 0.025 M HCl and 0.025 M Ca(ClO4)2?
