CHAPTER 8 REVIEW Chemical Equations And Reactions
A chemical equation is a concise description of a chemical reaction. Proper chemical equations are balanced. Write and balance the chemical equation described by Exercise 1. Write and balance the chemical equation described by Exercise 2. Write and balance the chemical equation described by Exercise 3. Write and balance the chemical equation described by Exercise 4. The formula for propane is C3H8. How would you write the balanced chemical equation in Exercise 12 if all the substances except water were gases and water itself were a liquid? Use the periodic table, an activity series, or solubility rules to predict whether single-replacement reactions or double-replacement reactions will occur. Up to now, we have presented chemical reactions as a topic, but we have not discussed how the products of a chemical reaction can be predicted. Here we will begin our study of certain types of chemical reactions that allow us to predict what the products of the reaction will be.

Chemistry Chapter 1 Answer Key
A single-replacement reaction is a chemical reaction in which one element is substituted for another element in a compound, generating a new element and a new compound as products. The hydrogen atoms in HCl are replaced by Zn atoms, and in the process a new element—hydrogen—is formed. A typical characteristic of a single-replacement reaction is that there is one element as a reactant and another element as a product. Not all proposed single-replacement reactions will occur between two given reactants. This is most easily demonstrated with fluorine, chlorine, bromine, and iodine. Collectively, these elements are called the halogens and are in the next-to-last column on the periodic table see Figure 5. The elements on top of the column will replace the elements below them on the periodic table but not the other way around. This is just one of many ways the periodic table helps us understand chemistry. Figure 5. Will a single-replacement reaction occur?

Class 11 Chemistry Revision Notes For Chapter 8 - Redox Reactions
If so, identify the products. Solution Because iodine is below chlorine on the periodic table, a single-replacement reaction will not occur. Because fluorine is above bromine on the periodic table, a single-replacement reaction will occur, and the products of the reaction will be CaF2 and Br2. Test Yourself Will a single-replacement reaction occur? Answer Yes; FeCl2 and I2 Chemical reactivity trends are easy to predict when replacing anions in simple ionic compounds—simply use their relative positions on the periodic table. However, when replacing the cations, the trends are not as straightforward. This is partly because there are so many elements that can form cations; an element in one column on the periodic table may replace another element nearby, or it may not. A list called the activity series does the same thing the periodic table does for halogens: it lists the elements that will replace elements below them in single-replacement reactions.

8: Quantities In Chemical Reactions
In this section you will explore the quantitative relationships that exist between the quantities of reactants and products in a balanced equation. This is known as stoichiometry. Stoichiometry, by definition, is the calculation of the quantities of reactants or products in a chemical reaction using the relationships found in the balanced chemical equation. The coefficients in front of the chemical formulas represent the numbers of molecules or formula units depending on the type of substance. Here, we will extend the meaning of the coefficients in a chemical equation. We can extend this technique even further. Recall that we can relate a molar amount to a mass amount using molar mass.

We can use that ability to answer stoichiometry questions in terms of the masses of a particular substance, in addition to moles. Often reactants are present in mole ratios that are not the same as the ratio of the coefficients in the balanced chemical equation. As a result, one or more of them will not be used up completely but will be left over when the reaction is completed. This measurement is called the percent yield. The limiting reagent is that reactant that produces the least amount of product. Mass-mass calculations can determine how much product is produced and how much of the other reactants remain. In the course of an endothermic process, the system gains heat from the surroundings and so the temperature of the surroundings decreases.

The quantity of heat for a process is represented by the letter q. The sign of q for an endothermic process is positive because the system is gaining heat. A chemical reaction or physical change is exothermic if heat is released by the system.
