- Learning Objective To calculate the quantities of compounds produced or consumed in a chemical reaction. A balanced chemical equation gives the identity of the reactants and the products as well as the accurate number of molecules or moles of each that are consumed or produced. StoichiometryA collective term for the quantitative relationships between the masses, the numbers of moles, and the numbers of particles atoms, molecules, and ions of the reactants and the products in a balanced chemical equation.
How Can I Get The Answers For Glencoe-mcgraw Hill Chemistry Book?
A stoichiometric quantityThe amount of product or reactant specified by the coefficients in a balanced chemical equation. In Section This section describes how to use the stoichiometry of a reaction to answer questions like the following: How much oxygen is needed to ensure complete combustion of a given amount of isooctane? This information is crucial to the design of nonpolluting and efficient automobile engines.- How many grams of pure gold can be obtained from a ton of low-grade gold ore? The answer determines whether the ore deposit is worth mining. If an industrial plant must produce a certain number of tons of sulfuric acid per week, how much elemental sulfur must arrive by rail each week? All these questions can be answered using the concepts of the mole and molar and formula masses, along with the coefficients in the appropriate balanced chemical equation.
Chemistry Matter And Change Chapter 11 Stoichiometry Answer Key
Stoichiometry Problems When we carry out a reaction in either an industrial setting or a laboratory, it is easier to work with masses of substances than with the numbers of molecules or moles. We will first present the method used in most other books for converting from the mass of any reactant or product to the mass of any other reactant or product using a balanced chemical equation outlined in Figure We will then show how this can be simplified by into a tabular algorithm. The key to everything is to start with a balanced chemical reaction Steps in Converting between Masses of Reactant and Product Convert the mass of one substance substance A to the corresponding number of moles using its molar mass.- From the balanced chemical equation, obtain the number of moles of another substance B from the number of moles of substance A using the appropriate mole ratio the ratio of their coefficients. Convert the number of moles of substance B to mass using its molar mass. It is important to remember that some species are in excess by virtue of the reaction conditions. For example, if a substance reacts with the oxygen in air, then oxygen is in obvious but unstated excess. Converting amounts of substances to moles—and vice versa—is the key to all stoichiometry problems, whether the amounts are given in units of mass grams or kilograms , weight pounds or tons , or volume liters or gallons.
- Figure If a typical 2 oz candy bar contains the equivalent of The initial step in solving a problem of this type must be to write the balanced chemical equation for the reaction. Inspection of Equation If we divide the number of moles of CO2 by its stoichiometric coefficient 6 and the number of moles of glucose by its stoichiometric coefficient of one the ratios, which can be called the reaction equivalents, are equal. Use the molar mass of CO2 In Chapter 6 , you discovered that this amount of gaseous carbon dioxide occupies an enormous volume—more than 33 L. We could use similar methods to calculate the amount of oxygen consumed or the amount of water produced. We just used the balanced chemical equation to calculate the mass of product that is formed from a certain amount of reactant.
Glencoe Chemistry_ Matter And Change Chapter 8 Assessment Answer Key
We can also use the balanced chemical equation to determine the masses of reactants that are necessary to form a certain amount of product or, as shown in Example There is another way of dealing with such problems which is easier to carry out. It starts by writing the balanced chemical equation and then drawing a table with five rows and as many columns as there are reactants and products and writing in the given mass.- Liquids have an indefinite shape and a definite volume.
