For example, in the above reaction one molecule of hydrogen H 2 and an atomic form of oxygen O are sufficient to produce a molecule of water H 2 O. But it is hard to find atomic oxygen. Hence, we represent it as molecule O 2. As can be seen the amount of reactants is not equivalent to the products. Hence, it is an unbalanced equation, which has to be balanced to give the following balanced equation.

Now, you know what a chemical equation is and why it should be balanced. Let us see how to balance these chemistry equations in a series of steps.

One molecule of water is formed due to combination of two molecules of hydrogen with one molecule of oxygen. However, this is an unbalanced reaction because there are two oxygen molecules on the reactants side but only one in the products side.

Now proceed to balance this equation. Make a note of elements on the reactants side and products side. Count the number of elements on each side. Products [2 Hydrogen atoms] [1 Oxygen atom ]. Now the equation becomes. Check if other elements are balanced. Hydrogen is unbalanced with two hydrogen atoms in reactants and four hydrogen atoms in the products. Now make it into four hydrogen atoms by multiplying the hydrogen molecule with two. Now the equation will be. So, there are four hydrogen atoms in both reactants and products and there are two oxygen atoms in both reactants and products.

This means that the chemical equation is balanced. By using the above approach you can balance any chemistry equations. You can find some chemical equation balancing activities in the following links: What is a Chemical Equation?

Need for Balancing Chemical Equations When a chemical reaction occurs, the reactants are converted to products. The scale is in perfect balance. All the marbles are identical. Your task is to find out the number of marbles in the bag without opening it. Suppose we remove all the extra marbles outside the bag in the left pan and find them to be 15 in number. If we remove the same number of marbles in this example, 15 from the right pan, then the scale will continue to be in perfect balance. Since only the bag is in the left pan and 10 marbles remain in the right pan, we know without opening the bag that there are 10 marbles in the bag.

From the above example, it is important to note that the scale is in perfect balance so long as the same operation addition, subtraction, etc. Similarly, in algebra, an equation remains balanced so long as the same operation addition, subtraction, multiplication, and division is performed on both sides.

If the same quantity is added to or subtracted from both sides of an equation, the two sides of the equation remain in balance. If both sides of an equation are multiplied or divided by the same number, the two sides of the equation remain in balance. The answer is obtained when only the variable exists on one side. Examples are given below. Subtract 27 from both sides: Note that the multiplication sign is often not written explicitly in algebra.

Thus, 3 multiplied by y is written as 3 y rather than 3 x y. Here, 3 is called the coefficient. The coefficient is the number by which the variable is being multiplied. If only y is written, then the coefficient is 1.

Subtract 34 from both sides:

Homework Help; Specialized Programs. ADD/ADHD Tutoring Programs; Balancing Chemical Equations This is the whole purpose of balancing a chemical equation. A hint for balancing. Single elements or any diatomic elements, should be left last to balance. This is because whatever coefficient you put in front of the element will not mess up. Balancing Chemical Equations A symbolic representation of a chemical reaction is a chemical equation. The starting materials, that is, the substrates are written on the left side of the chemical equation and products are written on the right side of the equation.
