Three possible resonance structures are shown below for the SO2Cl2 molecule. Using formal charge, determine the order of stability of the three structures (i.e. the order in which they contribute to the overall resonance hybrid structure).
calculate the temperature of the solution after the CaCl2 dissolves. (Assume no heat is lost to the container or the surroundings and the specific heat of the solution is the same as that of water.)
