Three gases (8.00G of methane CH4, , 18.0G of ethane C2H6, , and an unknown amount of propane, C3H8) were added to the same 10.0-L container. At 23.0 C, the total pressure in the container is 3.90ATM. Calculate the partial pressure of each gas in the container.
At 55.0C, what is the vapor pressure of a solution prepared by dissolving 75.8 g of LiF in 265 g of water?
What happens when the external pressure is lower than the vapor pressure of a liquid in a container?
Consider a galvanic (voltaic) cell that has the generic metals X and Y as electrodes. If X is more reactive than Y (that is, X more readily reacts to form a cation than Y does),
Devise tests which allow you to distinguish between the ions in each case.
The solubility of solute in a solvent depends on various parameters, such as temperature, pressure, the nature of the solute, and the nature of the solvent. Considering these parameters, identify the statements that are correct for the solubility ..
