I have no idea how to do this! Thank you for your help!
The half-life of a chemical rxn is 8.00 minutes. Starting with a 0.500 M soln, APPROXIMATELY how much unreacted material would be remaining after 46 minutes
An opened can of soda goes "flat" because the partial pressure of carbon dioxide is lower in the atmosphere than in the unopened can. Fish kills may occur in the summertime because an inadequate amount of oxygen is dissolved in the water. A soluti..
Explain, phenomena in terms of atomic structure and behavior. When you lightly bump into a car, why does it dent and not create a hole.
how many moles ofna ions are there in 1 mole ofna2so4 ? do you simply have to divide the relative atomic mass of na
The dielectric constant of water at room temperature is 78.3. Hint: your answer will come out negative because the interaction is attractive.
Initally, only H2S is present at a pressure of 0.123 atm in a closed container. What is the total pressure in the container at equilibrium
The compound X2Y is only partially dissociated in water solution to form X and Y2- ions. A 0.0100 m solution is found to freeze at -0.040°C. Calculate the apparent percent dissociation of X2Y. Kf for water = 1.86°C/m.
If an ideal gas is expanded reversibly, the heat absorbed qrev, can be expressed by the differential dqrev = Cv dT + P dV, Where Cv is a constant (called heat capacity at constant volume). Show that dqrev is an inexact differential.
