Skeleton Equation
A skeleton equation in chemistry is a simplified representation of a chemical reaction that only includes the chemical formulas of the reactants and products. It does not show the relative amounts of each substance involved in the reaction. This type of equation is a starting point for balancing chemical equations by adding coefficients to represent the correct stoichiometry.

...between the number of moles and the number of fundamental particles in a substance. Chemical equation the symbolic representation of a chemical reaction using symbols of the elements and chemical formulas. Complete ionic equation a chemical equation for a reaction in aqueous solution that shows all the dissolved ionic species present during the reaction. Conservation of mass the principle that atoms are neither created nor destroyed in a chemical reaction. Empirical mass the sum of the atomic masses in the empirical formula multiplied by the number of atoms of each element. Empirical formula the simplest positive integer ratio of atoms present in the compound. Flocculation a process in which the fine particles of a precipitate aggregate to form larger particles. Formula equation a chemical equation which shows all the ionic compounds and their states during an aqueous reaction, but does not specifically show their ionic forms in solution. Gravimetric analysis an experimental technique that involves the quantitative determination of a substance based on the measurements of mass. Hydrocarbons compounds made up of only carbon and hydrogen. Limiting reactant the reactant whose amount determines, or limits, the amount of the products formed. Molar mass the mass of one mole of a substance. Mole (mol) the mass of any substance which contains the same number of fundamental...

...6 Chemical Equations Now that you are familiar with atoms, symbols, molecules, formulas, and nomenclature, let's look at what happens when we mix substances together. The most important result of your efforts with this chapter will be your ability to write a balanced chemical equation that represents the reaction between two or more different substances that produces at least one new substance. Chemical equations are the chemist's shorthand. They show at a glance what substances have been mixed together and what new substance(s) have been produced. Chemists are able to predict the products of a mixture of substances even though they may never have actually mixed the substances in the laboratory. This is very important to research chemists trying to prepare new products that are useful and beneficial to mankind. You will learn how to complete and balance several kinds of chemical equations and how chemists recognize whether or not a reaction does indeed occur when substances are mixed. You will discover that some things remain unchanged during a chemical reaction...

...It is called a balanced chemical equation once the number of each type of atom is the same on either side of the arrow. Balanced equations used to be shown with an equals sign instead of the arrow which is why we have the word “equation”. Whenever a chemical reaction is represented by a chemical equation it should be balanced, because otherwise it does not convey all the information it can. As the next section will reveal, balanced equations allow an interpretation of events on the minute scale of atoms and molecules. The ability to understand these descriptions of chemical reactions will often be of great value to you in your work. Exercise 3 Try balancing the equations for the reactions in which propane (C 3 H 8) and butane (C 4 H 10) are burned in oxygen to form carbon dioxide and water. D Chemical equations in use Chemistry can help you understand more thoroughly the nature of the changes which occur when an object is manufactured, as it ages and deteriorates, and when it is treated. It can suggest why objects made of particular materials are subject to particular forms of change; you can use this knowledge to reduce or prevent further damage and to judge the suitability of conservation treatments. This section gives two examples to show how your knowledge gained through observation can be illuminated further by knowing some chemistry. Dl The manufacture and deterioration of fresco wall paintings crystals Listed below are the chemical names and molecular formulae for all the materials which are introduced in this section. Although you may find these a little foreign to you at present, much more will be said about how these formulae are arrived at and what the names mean, in Chapters 4 and 5 respectively. This need not worry you at present, although it may help you to refer to the table given in Chapter 2 on page 33 so that you can remind yourself of the shorthand symbols for the various elements listed...
