Yo someone hel mee wit disss... A sample of gas at 15.0 °C and 760.0 torr is heated to 375 K, and the volume is held constant. What is the new pressure of the gas? Give explanation or work too!! tnxx

Define dew point. i am writing this part to be able to ask the question

The bond energy for the van der waals bond between two helium atoms is 7.9×10−4ev. assuming that the average kinetic energy of a helium atom is (3/2)kbt, at what temperature is the average kinetic energy equal to the bond energy between two helium atoms

At a certain temperature the rate of this reaction is first order in hi with a rate constant of : 0.0632s2hig=h2g+i2g suppose a vessel contains hi at a concentration of 1.28m . calculate how long it takes for the concentration of hi to decrease to 17.0% of its initial value. you may assume no other reaction is important. round your answer to 2 significant digits.
