Chemical Substances – Nature and Behaviour
रासायनिक पदार्थ – प्रकृति और व्यवहार
In Class 10 Science, the chapter Chemical Substances – Nature and Behaviour introduces how substances are identified, transformed, and classified through their properties and reactions. Students explore chemical reactions and equations, acids, bases and salts, metals and non-metals, and carbon compounds. The chapter develops an understanding of observable changes, chemical behaviour, and the relationship between composition, properties, and everyday materials.
Chemical Reactions and Equations
रासायनिक अभिक्रियाएँ और समीकरण
In Class 10 Science, under the chapter Chemical Substances – Nature and Behaviour, this topic introduces chemical reactions as changes that form new substances. Students learn to identify reactants and products, represent reactions through word and chemical equations, and write balanced equations using correct chemical formulae while following the law of conservation of mass.
