Lithium oxide (Li2O) can be used to remove water from air. The balanced equation for the reaction of lithium oxide with water is: Li2O(s) + H2O(g) --> 2 LiOH(s) List the steps that you would have to follow to determine how many grams of water can be removed from the air by 250 g of Li2O, and identify the links between quantities. (Example: If you wanted to convert from μmol of a substance to grams, the steps would be μmol --> mol --> grams. The link between μmol and mol would be 1 μmol = 1E–6 mol, and the link between mol and grams would be the molar mass.)

Two nitro no2 groups are chemically bonded to a patch of surface. they can't move to another location on the surface, but they can rotate (see sketch at right). it turns out that the amount of rotational kinetic energy each no2 group can have is required to be a multiple of ε, where =ε×1.010−24 j. in other words, each no2 group could have ε of rotational kinetic energy, or 2ε, or 3ε, and so forth — but it cannot have just any old amount of rotational kinetic energy. suppose the total rotational kinetic energy in this system is initially known to be 32ε. then, some heat is removed from the system, and the total rotational kinetic energy falls to 18ε. calculate the change in entropy. round your answer to 3 significant digits, and be sure it has the correct unit symbol.
