compound1 + compound2 Compound3 + compound4 Two different compounds produce two other compounds. The cation of the first reactant combines with the anion of the second compound, and the anion of the first reactant ends with the cation of the second compound Prediction: Write the cation of one reactant with the anion of the other reactant and do the criss-cross. Then write the anion of the first reactant with the cation of the second reactant and do the criss –cross again. . Example: AgNO 3 + AlCl 3 AgCl + Al(NO 3 ) 3 Since: Cation of first reactant: Ag +1 Anion first reactant: (NO 3 ) -1 Cation of second reactant: Al +3 Anion of second reactant: Cl -1 V. Combustion of a hydrocarbon Hydrocarbon + oxygen carbon dioxide + water Hydrocarbons are used as fuels: petroleum, oil, and natural gas are hydrocarbons. This reaction is easy to predict. The products always include water and carbon dioxide. The reactants should be a hydrocarbon (a compound with hydrogen and carbon) and oxygen. In fact, every time you hear the word burning in chemistry you should assume that oxygen is combined with another element or compound. Prediction: Just write CO2 + H2O as the products. Remember that you should add O2 as a reactant when you see the word burning. CnHm + O2 CO2 + H2O Example: C4H10 + O2 CO2 + H2O
Practice Reaction Type and Predicting the Products For each of the following: The first one is an example. a. Determine the TYPE of reaction by looking at your Reaction Type Sheets and write the type in the space provided. Explain why the reaction is what you chose in the space provided. b. Determine the formulas of the reactants and the name and the formula(s) of the products, and write them in the spaces. Remember the diatomic elements. Really think about the products. The reaction of fluorine and sodium chloride is a Single replacement by more active non-metal . Explanation Both chlorine and Fluorine are non-metals (halogens) Reactant(s) formula(s) Product(s) formula(s) F 2 and NaCl Cl 2 and NaF Product(s) names the element chlorine and the compound sodium fluoride Whole equation: F 2 + NaCl Cl 2 + NaF 1. The reaction of aluminum and sulfur is a reaction. Explanation Reactant(s) formula(s) Product(s) formula(s) Product(s) names Whole equation: 2. The heating of gold (III) oxide is a reaction. Explanation Reactant(s) formula(s) Product(s) formula(s) Product(s) names
