The volume of an ideal gas is adiabatically reduced from 241 L to 78.5 L. The initial pressure and temperature are 1.00 atm and 310 K. The final pressure is 4.81 atm.
(a) Is the gas: 1 - monatomic, 2 - diatomic, or 3 - polyatomic? Give the number of the correct answer.
(b) What is the final temperature, in kelvins?
(c) How many moles are in the gas?
Write equations that show the processes that describe the first, second, and third ionization energies of a boron atom. I got the first and second ionization correct but for some reason it keeps telling me that my equation for the third ionization..
The heat evolved when a mole of octane undergoes complete combustion is 1303 kcal. This is called the heat of combustion. How many kcal of heat wil be generated when 148 grams of octane react with 952 grams of oxygen? Show calculations.
Determine water solubility under normal atmospheric conditions (assuming that Carbon dioxide obeys Henry's law?)
For the reaction, A = B + C, the rate law is k[A]. If it takes 80.0 seconds for 70.0% of a 10.0 gram sample of A to be transformed into products, what is the value of the rate constant.
