Chapter 8 – Chemical Reactions Notes Chemical Reactions: Chemical reactions are processes in which the atoms of one or more substances are rearranged to form different chemical compounds. Change is the law of nature. These notes are prepared by our panel of highly experienced teachers keeping in mind the level of preparation needed by the students to prepare for Class 10 … Example: Zn + H 2SO 4 → ZnSO 4 + H 2 In this equation, numbers of zinc, hydrogen and sulphate are equal on both sides, so it is a balanced chemical equation. Let us consider another reaction for writing and balancing of a chemical reaction. 1.1.2 Balanced Chemical Equations Recall the law of conservation of mass that you studied in Class … CBSE 10th Chemical reactions and Equations Unsolved Paper Click Button Below To Buy Solution BUY NOW WITH PayUmoney Only ₹ 25 OR Call us on 9557655662 for Paytm or UPI / NEFT payment Note This pdf file is downloaded from www.4ono.com. the mass is not the same on both sides of the equation. NCERT Books for Class 10 Science – English Medium. This chapter deals with chemical reactions and equations in detail. 2)Chemical Equations – Representation of a chemical reaction in terms of symbols and formulae of the reactants and products is known as chemical equation. Chemical Equation The simple form of representation of a chemical reaction in words is known as a word equation. In other words, you often notice substances change in the environment under different conditions. Students who are in Class 10 or preparing for any exam which is based on Class 10 Science can refer NCERT Book for their preparation. Unbalanced Chemical Equation. When steam is passed over red hot iron, hydrogen gas (H 2) is evolved and magnetic oxide of iron (Fe 3O 4) is obtained. NCERT Book for Class 10 Science Chapter 1 Chemical Reactions and Equations is available for reading or download on this page. 7 CHEMICAL REACTIONS AND EQUATIONS GIST OF THE LESSON 1) Chemical reaction— Chemical changes or chemical reactions are the changes in which one or more new substances are formed. Scientist classify these changes as physical changes and chemical changes. NCERT books Class 10 Science PDF (chapter-wise) in English, Hindi (Vigyan), and Urdu are provided as under: Class 9 Science NCERT Book Introduction; Chapter 1: Chemical Reactions and Equations; NCERT Solutions for class 10 Science. Chemical Reactions and Equations When a chemical change occurs, a chemical reaction takes place.
