A chemical equation is a symbolic representation of a chemical reaction, indicating the reactants and products in a reaction and the direction in which the reaction proceeds. French chemist Jean Beguin gets credit for formulating the first chemical equation in 1615.
A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and chemical formulas.
A chemical equation shows the starting compound(s)—the reactants—on the left and the final compound(s)—the products—on the right, separated by an arrow. In a balanced chemical equation, the numbers of atoms of each element and the total charge are the same on both sides of the equation.
What is a Chemical Equation? Chemical equations make use of symbols to represent factors such as the direction of the reaction and the physical states of the reacting entities. Chemical equations were first formulated by the French chemist Jean Beguin in the year 1615.
Page ID. Identify the reactants and products in any chemical reaction. Convert word equations into chemical equations. Use the common symbols, (s) (s), (l) (l), (g) (g), (aq) (a q), and → → appropriately when writing a chemical reaction. In a chemical change, new substances are formed.
Derive chemical equations from narrative descriptions of chemical reactions. Write and balance chemical equations in molecular, total ionic, and net ionic formats.
Summary. A chemical reaction is the process by which one or more substances are changed into one or more new substances. Chemical reactions are represented by chemical equations. Chemical equations have reactants on the left, an arrow that is read as "yields", and the products on the right.
