The following sections are covered in the chapter Chemical Reactions and Equations -ģ. Under, the explanation of the decomposition reaction, the process of electrolysis of water is comprehensively discussed along with its diagrammatic representation. Discussion on the effects of oxidation and reduction reactions in daily life such as in the case of corrosion and rancidity is covered in detail in the chapter, Chemical Reactions and Equations. The following types of chemical reactions are covered along with a detailed description of the features of those reactions along with suitable examples: Apart from this, writing the symbols of physical states of reactants and products involved in the chemical reactions in addition to its examples are also discussed in the chapter, Chemical Reactions and Equations. The color change is a sign that the reaction is occurring. The red color of the mercury oxide reactant becomes the silver color of mercury. Further, it deals with writing a balanced chemical equation which is extensively covered in a stepwise manner. When it is heated to a temperature above 500 o C, it easily decomposes into mercury and oxygen gas. Here, it explains the representation of chemical reactions in word equation form. Compounds that precipitate at pH 8.3 (certain hydroxides) may cause error by occlusion. The first part of the chapter, Chemical Reactions and Equations focuses on the concept of chemical equations. Sulfite and objectionable color or turbidit y must be eliminated. The observations of the activities mentioned determine whether a chemical reaction has taken place. Science NCERT Grade 10, Chapter 1, Chemical Reactions and Equations starts by citing a few daily life examples involving a chemical change.
