A chemical change is a change in which a substance loses its properties and forms a new type of substance that is different from the properties of the reactants. A chemical change is brought about by addition, decomposition, exchange of atoms or molecules, and the process by which chemical change occurs is called a chemical reaction.

A chemical reaction is a process that leads to the chemical transformation of one set of chemical substances to another. We will perform some experiments to understand this. We will take a magnesium ribbon burn with a dazzling white flame. And changes into a white powder. This powder is magnesium oxide. It is formed due to the reaction between magnesium and oxygen present in the air.

A combination reaction is a reaction where two or more elements or compounds combine to form a single compound. We will understand this concept with an experiment wherein we will combine Calcium oxide or you can also say it quicklime and water reaction after combination.

Further, in this virtual tour, we will understand the Decomposition Reaction. In this type of reaction, a single product decomposes in two or more two forms. The experiment which we will conduct would be taking a small amount of ferrous sulfate to the test tube and now we are giving heat to the ferrous sulfate.

Displacement Reaction’ is a chemical reaction, in which a more reactive element displaces a less reactive element from its compound. We will perform an experiment in one test tube. We will immerse two iron nails. The iron nail becomes brownish in color and the blue color of copper sulfate solution fades. This is because of Displacement Reaction.

In a Double displacement chemical reaction, two-time displacement reactions occur. It means two reactant ionic compounds exchange ions to form two new compounds with the same ions.  We will perform an experiment with sodium sulfate and barium chloride solution.

In this virtual tour, we will learn about oxidation and reduction. Substance gains oxygen during a reaction, it is said to be oxidized and the process is called oxidation. If a substance loses oxygen during a reaction, it is said to be reduced and the process is called reduction.
