Balancing Equations. The chemical equation described in section 4.1 is balanced, meaning that equal numbers of atoms for each element involved in the reaction are represented on the reactant and product sides.This is a requirement the equation must satisfy to be consistent with the law of conservation of matter.

By the end of this section, you will be able to: Define three common types of chemical reactions (precipitation, acid-base, and oxidation-reduction) ... process in which an element's oxidation number is increased by loss of electrons oxidation-reduction reaction (also, redox reaction ...

The periodic table organizes elements into groups and periods based on their chemical and physical properties. Elements in the same group share similar characteristics, like …

Aluminum, which is used in soda cans, is an element. A substance that can be broken down into chemically simpler components (because it has more than one element) is a compound. For example, water is a compound composed of the elements hydrogen and oxygen. Today, there are about 118 elements in the known universe.

Familiarity with a few basic types of reactions will help you to predict the products that form when certain kinds of compounds or elements come in contact. Most chemical reactions can be classified into one or more of five basic types: acid–base reactions A reaction of the general form acid + base → salt., exchange reactions A chemical ...

Classify chemical reactions as one of these three types given appropriate descriptions or chemical equations; Identify common acids and bases; Predict the solubility of common inorganic compounds by using solubility rules; Compute the oxidation states for elements in compounds

These properties can be used to sort the elements into three classes: metals (elements that conduct well), nonmetals (elements that conduct poorly), and metalloids (elements that have intermediate conductivities). The periodic table is a table of elements that places elements with similar properties close together (Figure 1.22). You will learn ...

The smallest part of an element that maintains the identity of that element is called an atom The smallest part of an element that maintains the identity of that ...

The majority of elements in the periodic table are classified as metals. The transition metals lie in the center of the table, spanning groups three through 12. These …

Periodic variations in size and chemical properties are important factors in dictating the types of chemical reactions the elements undergo and the kinds of …

24 4.2 Classifying Chemical Reactions Learning Objectives.
