what names are given to the materials at the end of a chemical reaction
Chemical reaction Chemical equations are used to graphically illustrate chemical reactions. They consist of chemical or structural formulas of the reactants on the left and those of the products on the right. They are separated by an arrow (→) which indicates the direction and type of the reaction; the arrow is read as the word "yields".[7] The tip of the arrow points in the direction in which the reaction proceeds. A double arrow (⇌) pointing in opposite directions is used for equilibrium reactions. Equations should be balanced according to the stoichiometry, the number of atoms of each species should be the same on both sides of the equation. This is achieved by scaling the number of involved molecules (   A , B , C  {\displaystyle {\ce {A,B,C}}}  and   D  {\displaystyle {\ce {D}}}  in a schematic example below) by the appropriate integers a, b, c and d.[8]
