Chem 1411 Chapter 3 Mass Relations In Chemical Reactions Homework A metal will replace the positive ion and a nonmetal will replace the negative ion. the general pattern is: a bc → ac b. some other examples are: cl2 (g) 2ki (aq) → i2 (s) 2kcl (aq) notice in this example chlorine will form a negative ion, so chlorine will take the place of the iodine. Copper (ii) nitrate pentahydrate. cu (no3)2⋅5h2o. lino2⋅h2o. lithium nitrite monohydrate. give the mass percent of carbon in c14h19no2. 72.07%. study with quizlet and memorize flashcards containing terms like an ionic bond is best described as, a covalent bond is best described as, an ionic bond involves transfer of electrons from and more. The conversion of step 1 requires the molar mass of lioh (6.94 16.00 1.01 = 23.95 g mol). the conversion of step 2 is based on a stoichiometric relationship from the balanced chemical equation: 2 mol lioh mol co2. for the step 3 conversion, we use the molar mass of co2 12.01 2(16.00) = 44.01 g mol. Chem 1411 sample final exam 1. when 0.75 g of hydrazine, n2h4, decomposes, the mass of hydrogen produced should be (a) equal to 0.75 g because mass is conserved. (b) equal to twice the mass of the nitrogen because of stoichiometry. (c) less than the mass. solutions available.
