Chemical reactions- The transformation of chemical substance into a new chemical substance by making and breaking of bonds between different atoms is known as Chemical Reaction. Signs of a chemical reaction- These factors denote that a chemical reaction has taken place- change of state of substance, change of color of substance, evolution of heat, absorption of heat, evolution of gas and evolution of light.

Class 10 Science Chapter 1 Notes

Class 10 Chapter 1 Chemical Reactions and Equations describe the various processes that happen around us in the World like Rusting of Iron, Decomposition, etc. The topic of Chemical Reactions and Equations would include all the essential topics alongside with a thorough and detailed explanation. Class 10 Chapter 1 Science notes cover all the crucial equations and terms in a simple and easy to understand way with examples and diagrammatic representation. The list that we have in an overview manner of the list of topics and subtopics coming under the Class 10 Science Chapter 1 Chemical Reactions And Equations are as follows:. Physical and Chemical Changes. Various Chemical Equations. Conservation of Mass.

Count the number of atoms of all the elements in the reactants and products separately. In reactants In products No. These are the chemistry class 10 chapter 1 Chemical Reactions and Equations notes. Topics covered in this page are Types of chemical reactions Combination reactions Decomposition reaction Displacement reactions Double displacement reactions Oxidation and Reduction reactions Types of chemical reactions Some of the important types of chemical reactions are: Combination reactions Decomposition reaction Displacement reactions Double displacement reactions Oxidation and Reduction reactions Combination reactions: Those reactions, in which two or more substances combine to form a single substance, are called combination reactions. In a combination reaction, two or more elements can combine to form a compound; two or more compounds can combine to form a new compound; or an element and a compound can combine to form a new compound.

Download as PDF. Chemical reactions taking place are represented by fully balanced chemical equations, i. A simple equation is balanced by hit and trial method so that same total number of charges and atoms appear on both sides of the equation. For example when iron combines with steam to form FegO 4 and H 2 , it is balanced in the following steps:. If the reaction is complicated , i. This is called partial equation method.

Chemical Reactions and Equations Class 10 Notes

Chemical Reactions and Equations: Balanced and unbalanced chemical equations and balancing of chemical equations. Chemical Reaction: The transformation of chemical substance into another chemical substance is known as Chemical Reaction. For example: Rusting of iron, the setting of milk into curd, digestion of food, respiration, etc. In a chemical reaction, a new substance is formed which is completely different in properties from the original substance, so in a chemical reaction, a chemical change takes place. Only a rearrangement of atoms takes place in a chemical reaction. Example: The burning of magnesium in the air to form magnesium oxide is an example of a chemical reaction.

Revision is one of the most important aspects of learning as it helps you to remember facts, figures, and topics that you have covered earlier. Students are always advised to summarize whatever they have learned as Revision Notes. A physical change occurs when a substance changes but no new substance is formed. The chemical composition remains the same. Examples: Crushing of bottles, cutting of paper, etc.
