In this type of change, only the physical properties such as colour, shape or size are of the reactants change. These changes are reversible and temporary in nature. For example, boiling of water, where water changes into water vapour on boiling. A chemical reaction is when one or more substances react and give rise to one or more substances as a product.

The substances so formed can either be chemical elements or compounds. There are several factors that can help us determine a chemical reaction, and they are:. In a chemical reaction, there can be an evolution of gas. In a chemical reaction, there can be a significant change in temperature. A precipitate is formed in a chemical reaction. Change in colour of the reactants. Change in the state of the reactants. There are various types of chemical reactions depending upon multiple Important Question Of Cbse 10th Class Science Workbook factors.

The chemical reactions are as follows:. Combination reaction. Decomposition reaction. Single Displacement reaction. Double Displacement reaction. Redox Reaction. Endothermic reaction. Exothermic reaction. Neutralisation reaction. Precipitation reaction. A Chemical equation is a symbolic representation of chemical reactions that involve chemical formulas and symbols.

It involves both the reactants and products. The reactants are written on the left side, while the products are written on the right side of the equation. Chemical Symbol is a chemical representation given to an element. For example, The chemical symbol of Zinc is Zn. Valency refers to the combining capacity of an element. It can be defined as the number of electrons gained or lost by an atom while it undergoes a chemical reaction.

While writing a chemical reaction, we should keep some rules in mind, and those rules are as follows:. Advertisement Remove all ads. English - Communicative. English - Language and Literature. Social Science. Carbon Compounds. Metals and Non Metals. Periodic Classification of Elements. Acids, Bases and Salts. Chemical Reactions. Heredity and Evolution.

Important Long Answer Type Questions.

Get here a collection of long answer type questions to be prepared for the 5 marks answer type questions:. How is the direction of a magnetic field at a point determined? The direction of the magnetic field at a point can be found by placing a small magnetic compass at that point. The north end of the needle of a compass indicates the direction of magnetic field at a point where it is placed.

Inside the magnet, the field lines emerge from the south pole and terminate at the north pole, as shown in the given figure. Explain how antacids give relief from acidity. Write the name of one such antacid. How does the pH will change as it turns to curd? Explain your answer. Why does this milk take a longer time to set as curd?

How do they prevent tooth decay? Antacids neutralize the excess of acid in our body and gives relief from hyperacidity. Sodium hydrogencarbonate is one of such antacid.

They neutralize the acid formed in mouth which causes tooth decay. Atoms of eight elements A. D, E, F. G and H have the same number of electronic shells but different number of electrons in their outermost shell. It was found that elements A and G combine to form an ionic compound. This compound is added in a small amount to almost all vegetable dishes during cooking. Oxides of elements A and B are basic in nature while those of E and F are acidic.
