In this reaction, magnesium reacts with sulphuric acid to produce magnesium sulfate and hydrogen gas. Now, we need to count the number of atoms of each element involved in the reaction and tabulate to find out whether the chemical equation is balanced or not. For the above equation, Thus, ...
If possible, make the equation more informative by indicating the physical states of the reactants and products, the heat changes that occur in the reaction, and the conditions under which the reaction occurs. This step may be skipped if you do not have enough information about the physical s...
How to Balance a Chemical Reaction? Step 1: Identify each element found in the equation. The number of atoms of the element must be the same on each side of the equation. Step 2: Check the net charge on each side of the equation. The net charge must be the same on each side. Step...

Such an equation is ‘unbalanced’ because the mass is not the same on both sides. Therefore, the above equation is a skeletal chemical equation for the reaction between magnesium and oxygen. Solved Examples for You Question: Why are iron articles painted? Solution: When iron comes in contact...
Examples of Chemical Reactions Lesson Summary Register to view this lesson Are you a student or a teacher? FAQ What is one example of a chemical reaction? One example of a chemical reaction is the combination of hydrogen gas and oxygen gas to form liquid water. This is known as a synthesis...
Thus, in a chemical reaction, the total mass of matter involved in the reaction should be constant. Hence, the mass of the reactants equals the mass of the products. Because of this, when a chemical equation is used to represent a reaction, the number of atoms or moles of each eleme...
Let’s take a closer look at the types of reactions and get examples: Synthesis or Direct Combination Reaction In a synthesis, direct combination, or composition reaction, two (or more) reactants combine to form a more complex product. The general form of the reaction is: A + B → AB ...
Therefore, equations depicting reactions must be balanced; that is, the same number of atoms of each kind must appear on opposite sides of the equation. The balanced equation for the iron-sulfur reaction shows that one iron atom can react with one sulfur atom to give one formula unit of ...
