61 The Castle of Quantification A major development in the discovery of Nature's Chemical Laws was the use of the balance during experiments. By quantifying the mass of reactants and products, chemists uncovered regularities and created new generalizations about the physical world. These generalizations are important to us today. For instance, in industry the optimization of product is often extremely important economically. By knowing the relationship between reactants and products, chemists can predict how much product will be made from the amount of reactants they stafted out with; this minimizes the quantity of wasted reactants and thereby increases efficiency of the manufacturing process. Your job is to find this relationship. 1l l' ,.: ',:'- '1," ,,,,,,

49 The Redox Arena Redox is a compressed way of writing reduction and oxidation. Reduction refers to an atom gaining electrons and oxidation involves an atom losing electrons. Together, this process is very telling, in that it points to a very important aspect of chemical change: the electrons. For a reaction to occur, new bonds must form between atoms. lt is the ability of electrons to be shared or transferred between atoms that cause new bonds to form. The electron, more so than the proton or neutron, is the active player in the arena of chemical change.
