Draw the Lewis structure and structural formulas for CCl3F. Sketch the spacefiling model and the charge-density model for this molecule.
Describe the major absorption bands in the IR spectrum - indicate the bonds responsible for those peaks which prove you have synthesized isopentyl acetate and that it is an ester.
Calculate kinetic energy of a 2 ton truck lumbering along at 60 mi/hr.
Calculate the change in entropy (in J/K) when 89.8 g of nitrogen gas is heated at a constant pressure of 1.50 atm
A sample of neon gas is held in a rigid 1.814L container with a pressure of 1.273atm at 25 C. 3.193g of an unknown gas is added to the container. The temperature remains constant, but the pressure rises to 2.386atm. What is the molar mass of the a..
