The equilibrium conditions for SO2, O2, and SO 3 are important in sulfuric acid production. When a 0.0200 mol sample of SO3 is introduced into an evacuated 1.67 L vessel at 900K, 0.0132 mol SO3 is found to be present at equilibrium. What is the value of Kp for the dissociation of SO3 at this temperature?
What is the value of Kf for acetic acid, given that its freezing temperature is 16.6 C and its density is 1.049 g/mL?
Microwave ovens heat food by creating microwave electromagnetic radiation that is absorbed by water molecules in the food. Any material that does not have water in it will not absorb the radiation and will not get hot.
