How is the concentration of Cl determined by mercuric nitrate? Is there a color change at various levels? (similar to the Cl test for swimming pools and you'd have to match a particular color to a particular concentration?)
A Balloon with a volume of 2.00 L is at a pressure of 1.5 atm and a temperature of 20C. If the balloon is put into a container and the pressure is increased to 2.0 atm and the temperature is raised to 25C, what is the new volume of the balloon?
The pressure in a gas arises because the particles of a gas strike each other and the walls of their container, exerting a ________. The larger the number of gas particles in a particular volume, the _______ the pressure within the gas.
