There are two chemicals used in this reaction, 1,6-hexadiamine (which is in a water solution) and adipoyl chloride (which is in a hexane solution). Think back to what you learned in this course about solutions and intermolecular forces. Why don't these to "mix" together (in other words, make a homogenous solution) when combined? Why do they separate into layers
For the following reactions, identify the type (combination, combustion, decomposition, displacement, methathesis [double-displacement)] neutralization), balance the reaction, and for the redox reactions identify the oxidizing agent and reducing a..
