The names and chemical formulae of some chemical compounds are written in the first two columns of the table below. each compound is soluble in water. imagine that a few tenths of a mole of each compound is dissolved in a liter of water. then, write down in the third column of the table the chemical formula of the major chemical species that will be present in this solution. for example, you know water itself will be present, so you can begin each list with the chemical formula for water (h2o).note: "major" chemical species are those present in concentrations greater than 10^-6 mol. major species present when dissolved in waterzinc iodide zni2 nitrous oxide n2osodium nitrate nano2glucose c6h12o6nickel (ii) iodide nil2

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.
