With standard enthalpy change calculation?
calculate the standard enthalpy change of the reaction clo(g) + o3(g) > clo2(g) = 02(g)
standard enthalpies are: clo(g) is 101; for o3 is 142.3; for o2 is 0; for o(g), is 247.5.

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?
