Chemical Formulas and Composition Stoichiometry

Rock candy is composed of large crystals of sucrose (sugar, C 20,H22). A ball-and-stick model (C = black, [Pg.43]

0 = red, H = white] of sucrose is superimposed on an electrostatic charge potential surface that shows the relative charges on the atoms (red = most negative, green = neutral, blue = most positive). [Pg.43]

The word stoichiometry is derived from the Greek stoicheion, which means first principle or element, and metron, which means measure. Stoichiometry describes the quantitative relationships among elements in compounds (composition stoichiometry) and among substances as they undergo chemical changes (reaction stoichiometry). In this chapter we are concerned with chemical formulas and composition stoichiometry. In Chapter 3 we shall discuss chemical equations and reaction stoichiometry. [Pg.47]
