Compare saponification and hydrogenation. select the correct answer below: saponification is a process that produces soap, usually from fats and lye. hydrogenation is a chemical reaction between molecular hydrogen (h2) and another compound or element, usually in the presence of a catalyst. saponification is a chemical reaction between molecular hydrogen (h2) and another compound or element, usually in the presence of a catalyst. hydrogenation is a process that produces soap, usually from fats and lye. saponification is the making of a fat or triacylglycerol from the components of glycerol and fatty acids. hydrogenation of a fat or a triacylglycerol is the reverse process of saponification.

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.
