The 9.163 g their air Air Cs equals 1005J/KG c in an inflated balloon is warmed over a toaster and increases in temperature by 11°C the balloon expands against one atmospheric pressure and changes volume for one liter to two liters what is the change in internal energy?
solution with a pipet to a second 500.0 mL volumetric flask and diluting to the mark. Find the concentration of Ag+ in the dilute solution.
We are asked to construct an energy level diagram (molecular orbital) for the molecule SO. We are then asked to comment on the ionic species of SO - bond order, bond distance etc. So far so good.
