THICKNESS OF ZINC ON A PIECE OF GALVANIZED METAL Department of Biology‚ College of Science‚ University of the Philippines Baguio ABSTRACT The experiment was performed to be able to determine the thickness of zinc on a piece of galvanized metal. It also aimed for the students to be introduced to the reactivates of metals with acids as well as for them to develop some feeling for the size of an atom. In determining the thickness of the zinc coating on the metal‚ students‚ knowing the density of zinc

Marie Alessandra T. Reyes Group 4 18L Quantitative Determination of the Acidity of Soft Drinks I. Introduction Soft drinks are well known beverages among the young that are consumed mostly for pleasure. These beverages normally contain flavoring‚ sweeteners coloring‚ carbonic acid and acids. Carbonic acid and acids play an important part in the formulation of soft drinks. They enhance the flavor and give a pleasant refreshing ’lift ’ to the drink. The type of acid used can even affect the palatability

CHEMICAL EQUILIBRIUM I. Introduction In a chemical reaction‚ when reactants are mixed together in a reaction vessel‚ the whole of the reactants do not get converted into products. After some time‚ there will come a point when a fixed amount of reactants will exist in harmony with a fixed amount of products; neither amount will change anymore. This state is called chemical equilibrium (Birk‚ 1994; Jones‚ 1987; LeMay‚ 2002). There are three characteristics of a system in chemical equilibrium: a
