Now, the number of atoms of Y is balanced but not the number of atoms of X. To balance Y on both sides, multiply RHS by 2, i.e.,
The number of atoms of elements X and Y in the above-mentioned equation is shown below. The word equation for this reaction would be For example, reactants X and Y 2 react to form a compound XY. The first step in balancing an equation is to count the number of atoms of each element on both sides of the equation. The arrow indicates that the reaction proceeds towards the formation of C and D. In this chemical equation, A and B are the reactants, and C and D are the products. In between the reactants and the products an arrow sign (⟶) is inserted to show which way the reaction is occurring.

A plus (+) sign is added between the formulae of the products. The products of reaction are written in terms of their symbols or molecular formulae on the right-hand side of the equation. A plus (+) sign is added between the formulae of the reactants. The reactants taking part in the reaction are written in terms of their symbols or molecular formulae on the left-hand side of the equation. Sometimes ‘△’ is written above the arrow to show that heating is necessary to bring about a chemical reaction.Ĭertain rules have to be followed while writing a chemical equation. Sometimes the symbol ‘↑’ is used to indicate the release of a gas.ĥ. The symbol (aq) represents an aqueous solution.Ĥ. The state symbols (s), (l) and (g) represent the solid, liquid and gaseous states respectively. Put in the state symbol of each substance.ĢFe(s) + 3CuCl 2(aq) ⟶ 2FeCl 3(aq) + 3Cu(s)ģ. (Note: Coefficients are the numbers in front of the formulae.)Īs a result, the numbers of Fe atoms and Cu atoms are not balanced. Reactants: Iron, Fe and copper(II) chloride, CuCl 2 Products : Iron(III) chloride, FeCl 3 and copper, Cuĭetermine the number of atoms of each element on both sides of the equation.īalance the equation by adjusting the coefficients. Identify the reactants, products and their formulae. Reaction: Iron filings react with copper(II) chloride to produce iron(III) chloride solution and copper. Table below shows how a chemical equation can be constructed. Therefore, a chemical equation must be balanced.Ģ. 
This means that the numbers of atoms before and after a chemical reaction are the same. Based on the law of conservation of mass, matter can neither be created nor destroyed. What is Empirical and Molecular Formula?ġ.How do you know the Order of Elements in a Chemical Formula.What is the Molar Volume of a Gas at STP?.
How do you Calculate the Molar Mass of a Substance?. What is One Mole and How many Particles are in a Mole?. What is the Relative Atomic Mass and Relative Molecular Mass of an Element?. In an equation, the reactants are written at the left-hand side whereas the products are written at the right-hand side. (b) New substances formed are called products. (a) Starting substances are called reactants. The symbols and formulae of the substances (elements or compounds) are arranged to show the reactants and products of a chemical reaction.Ī chemical reaction occurs when starting substances react to produce new substances. A chemical equation is a shorthand representation of a chemical reaction using the symbols and formulae of substance involved in the chemical reaction. All chemical reactions are represented by chemical equations.
