Suppose 2.00 mol of an ideal, monatomic gas is initially at a pressure of 3.00 atm and a temperature t 350 k. it is expanded irreversibly and adiabatically (q 0) against a constant external pressure of 1.00 atm until the volume has doubled. (a) calculate the nal volume. (b) calculate w, q, and u for this process, in joules. (c) calculate the nal temperature of the gas.

To calculate percent by mass, use the equation below: calculate the percent by mass of each element. %n = % %h = % %o = %

Which of your 24 wells had indications that a chemical reaction occurred? how were you able to tell that a chemical reaction occurred? which of your 24 wells had indications that a physical reaction occurred? how were you able to tell that a physical reaction occurred? report on both mixing and evaporation. make a general statement about whether your hypotheses were validated or rejected. must your hypotheses be correct for this to be a successful laboratory?
