THE CHEMISTRY OF MILK | Dairy Processing Handbook

THE CHEMISTRY OF MILK. The principal constituents of milk are water, fat, proteins, lactose (milk sugar) and minerals (salts). Milk also contains trace amounts of other substances such as pigments, enzymes, vitamins, phospholipids (substances with fatlike properties), and gases. The residue left when water and gases are removed is called the

A chemical equation is a description of the proportion of reactants than coine to yield a specific chemical product. For example, when sodium and chlorine coine, they form sodium chloride which can be written Na + Cl --> NaCl

Displacement Reaction Definition and Examples

9/9/2019· Single displacement reactions are reactions where one reactant replaces part of the other: AB + C → AC + B. An example is the reaction between iron and copper sulfate to produce iron sulfate and copper: Fe + CuSO 4 → FeSO 4 + Cu. Here, both iron and copper have the same valence. One metal ion takes the place of the other, bonding to the

Balancing redox equations (article) | Khan Academy

To balance a redox equation using the half-reaction method, the equation is first divided into two half-reactions, one representing oxidation and one representing reduction. The equations for the half-reactions are then balanced for mass and charge and, if necessary, adjusted so that the nuer of electrons transferred in each equation is the
