Suppose the reaction system UO2(s) 1 4HF(g) 34 UF4(g) 1 2H2O(g) has already reached equilibrium. Predict the effect that each of the following changes will have on the equilibrium position. Tell whether the equilibrium will shift to the right, will shift to the left, or will not be affected. a. More UO2(s) is added to the system. b. The reaction is performed in a glass reaction vessel; HF(g) attacks and reacts with glass. c. Water vapor is removed.
August 30, 2016 (Chapter 2, continued) Density Mass d= m o Density= Volume v o Unit for density is g/cm or g/mL. o cm (or cc’s for students going into medicine) is the same as mL. o Finding the density for solid objects: Take a graduated cylinder and fill with water. Place the object into the water gently so that you do not splash any water or break the graduated cylinder. Figure out the water displacement. (Volume) Weigh the object using a scale. (Mass) o Finding the density for liquids: Place a dry and empty container on a scale and tare the scale so that it resets to zero. Place the liquid into the container to measure the weight of the
