C 3H 8 (g) + 5O 2 (g) → 3CO 2 (g) + 4H 2O (g) Answer the following questions. 11. You mix two clear solutions. Instantly, you see a bright yellow precipitate form. What type of reaction did you just observe? Explain your answer. 12. What type of reaction occurs when you strike a match? 13. Solid sodium reacts violently with chlorine gas. The product formed in the reaction is sodium chloride, also known as table salt. What type of reaction is this? Explain your answer. 14. Hydrogen-powered cars burn hydrogen gas to produce water and energy. The reaction is: 2H 2 (g) + O 2 (g) → 2H 2O (g) + Energy While this reaction can be classified as a synthesis reaction, it is sometimes referred to as combustion. What characteristics does this reaction share with other combustion reactions? How is it different? 14.2
Name: Date: 14.2 Predicting Chemical Equations Chemical reactions cause chemical changes. Elements and compounds enter into a reaction, and new substances are formed as a result. Often, we know the types of substances that entered the reaction and can tell what types of substance(s) were formed. Sometimes, though, it might be helpful if we could predict the products of the chemical reaction—know in advance what would be formed and how much of it would be produced. For certain chemical reactions, this is possible, using our knowledge of oxidation numbers, types of chemical reactions, and how equations are balanced. In this skill sheet, you will practice writing a complete balanced equation for chemical reactions when only the identities of the reactants are known. Review: Chemical equations Recall that chemical equations show the process of a chemical reaction. The equation reads from left to right with the reactants separated from the products by an arrow that indicates “yields” or “produces.” In the chemical equation: Two atoms of lithium combine with one molecule of barium chloride to yield two molecules of lithium chloride and one atom of barium. The equation fully describes the chemical change for this reaction. For reactions such as the one above, a single displacement reaction, we are often able to predict the products in advance and write a completely balanced equation for the chemical change. Here are the steps involved: 1. Predict the replacements for the reaction. In single displacement reactions, one element is replaced by a similar element in a compound. The pattern for this replacement is easily predictable: if the element doing the replacing forms a positive ion, it replaces the element in the compound that forms a positive ion. If the substance doing the replacing forms a negative ion, it replaces the element in the compound that forms a negative ion. For the reaction described above, we could predict that the lithium would replace the barium in the compound barium chloride since both lithium and barium have positive oxidation numbers. The resulting product would pair lithium (1+) and chlorine (1-): the positive/negative combination required for ionic compounds. 2. Determine the chemical formula for the products. Once you have determined which elements will be swapped to form the products, you can use oxidation numbers and the fact that the sum of the oxidation numbers for an ionic compound must equal zero in order to determine the chemical formula for the reaction products. 3. Balance the chemical equation 2Li + BaCl2 → 2LiCl + Ba Once you have determined the nature and formulas of the products for a chemical reaction, the final step is to write a balanced equation for the reaction. 14.2
