Consider two empty containers A and B whose volumes are 10mL and 20mL respectively. 1mL of liquid water is put into each container and the temperature of each container is adjusted to 20°C. The gas pressure in container B, which still has some liquid water in it, is found to be 17 torr. How would the pressure in container A AND the amount of liquid water in container A compare to that of container B?
Can someone please explain in detail how to do how to determine the amount of liquid water in container A compare to that of container B? I'm confused on that part.

There are three containers whose size are 3 pints, 5 pints, and 7 pints, respectively. The 3-pint and 5-pint containers start out full of water, but the 7-pint container is initially empty. We are allowed one type of operation: pouring the contents of one container into another, stopping only when the source container is empty or the destination container is full. We want to know if there is a sequence of pourings that leaves exactly 6 pints in the 7-pint...

n this exercise, weighed samples of a solid unknown containing NaCl and NaHCO3 react with hydrochloric acid. The volume of the CO2 liberated by the reaction in the gas phase is measured with a gas collection syringe. From the volume we can calculate the number of moles of CO2 in the gas phase using the ideal gas approximation. Since the CO2 is generated in an aqueous environment (aqueous HCl), some CO2 will dissolve in the liquid phase. The amount of...

ReviewI Constants Periodic Table The air that surrounds us is mostly empty space, and it can be almost a factor of one thousand less dense than water. Within that mostly empty space, gas molecules are moving around at high speed and colliding with each other, and if you are in an enclosed space, they are also colliding with the walls. We can more easily observe the behavior of a gas by confining it to a container with a known volume,...

Introduction Titration is a common analytical technique that is used to verify the concentrations of chemicals before they are sold as commercial products, in a process known as quality control. In this lab, you will be using a redox titration to find the concentration of the strong oxidizing agent hypochlorite (CIO) which is the active ingredient in bleach. Oxidizing and reducing agents are often determined using a redox titration....
