Sample text

There are many reasons for this, but the principal one is that most reactions do not go to completion; they establish an equilibrium system (see Chapter 14 for a discussion on chemical equilibrium). For whatever reason, not as much product as expected is formed. We can judge the efficiency of the reaction by calculating the percent yield. 5 g Fe2O3 could be formed. 3 g Fe2O3 formed. Calculate the percent yield. 5 g 3-5 Percent Composition and Empirical Formulas If we know the formula of a compound, it is a simple task to determine the percent composition of each element present.

The names of the metal/nonmetals in this section are: NaF ϭ sodium fluoride CaS ϭ calcium sulfide AlN ϭ aluminum nitride CaCl2 ϭ calcium chloride Al2O3 ϭ aluminum oxide The presence of a polyatomic ion in a compound requires substituting the name of the polyatomic ion for the name of the cation or anion in a comparable metal/nonmetal compound. We will use no prefixes. Let’s try an example. What is the formula of potassium phosphate? We can use our method for assigning the charge of cations to predict that potassium will be present as a Kϩ ion.

CaSO4 d. (NH4)3PO4 e. Fe(NO2)2 26. Give the formula of each of the following compounds. a. sodium phosphate b. ammonium bicarbonate c. magnesium nitrite d. copper(I) chloride e. iron(III) oxide 27. Name each of the following acids. a. HF b. HNO3 c. H3PO4 d. H2CO3 e. H2SO4 28.
