The last chapter is about the conservation of natural resources. In previous classes, ncert science class 10th pdf generator were Ncert Science Class 10th Pdf 00 introduced to physical and chemical changes.
The chemical changes signify 10h chemical reactions. The indicators of chemical reactions are explained with sccience indicators like change in physical state, change in color, change in temperature and evolution of gas.
These are explained with some experimental examples. After that writing of chemical equation has been explained.
Sience is symbolic representation of chemical generatro. Also, it has been explained that how such equations can be more informative. For example, balancing a chemical equation will signify that the chemical reactions follow law of conservation of mass. Other information like physical states and conditions required for reactions are mentioned.
After that various types of chemical reactions are explained are discussed. The types of chemical reactions are �combination reaction, decomposition reaction, displacement reaction, double decomposition reaction. On basis of energy, exothermic and endothermic reactions are mentioned. Redox reactions are explained which are combination of reduction reaction and oxidation reaction.
All types of reactions are explained with suitable example with their respective chemical equation. Chapter 2 - Acid, Base and Salts Acid and bases are studied in earlier classes. Acids are defined as substances which are sour in taste and turn blue litmus red. Examples of acids are sour fruits like, Bases are defined as substances which are pdd in taste and turns red litmus blue.
Examples of bases are neem, clove, vinegar. Here, acids and bases are defined chemically. Bases are chemically those substances which generate OH- ions in aqueous solutionIf not they are weak acids.
After that, various chemical and olfactory indicators are discussed; this indicates ncert science class 10th pdf generator presence of acids or base in the solution. Bases are said to be strong if whole of them get dissociated in water to form OH- ions. For example, Methyl generatoe is a scirnce indicator.
It turns red in acidic solution and yellow in basic solution. Olfactory indicators are indicators which changes odor after coming in contact with acid and generato.
For geenerator, smell of clove vanishes when scoence in contact with acid. After that acids and bases reactions are generagor with metals, metal oxides and metal carbonates. Reactions between acids and bases are also discussed. They are known as neutralization reactions. Salt is one of the products formed by acid, base reaction. The various types of salts are discussed based on the strength of acid or base. The pH scale Indicates if the solution is acidic, basic our neutral.
It is an scale from So, is acidic, 7 is neutral, basic solution. Clsss indicator is a mixture of several indicators. Chloro-alkali process is performed of salt solution. The various chemical substances are formed after reactions, directly or in-directly clas used for various process. Their formation and uses are explained in this chapter.
Chapter 3 - Metals and Non-Metals The chapter c,ass with physical properties of metals and non-metals. The parameters discussed are some physical properties, like melting and boiling points, physical state at room temperature, ductility, malleability, tensile strength. The metals and non �metals are differentiated on the basis of physical properties.
But there are some expectations based on physical properties. For example iodine is non-metal but has lustrous appearance as metal. Mercury is metal but liquid at room temperature. There are more such exceptions. Therefore, classification of metals and non-metals, are based on chemical properties. Chemical reactions of metals with oxygen ncert science class 10th pdf generator, water, acids and other metal salts are discussed.
The reactions and their condition depends upon the reactivity series. The metals on top of reactivity series are sodium ncert science class 10th pdf generator Potassium.
They perform vigorous reactions. Nature of metallic oxides is discussed. Ncert science class 10th pdf generator Metal oxides are basic in nature. But, some of them like aluminum oxide and zinc oxide can be both acidic and basic and hence known as amphoteric oxides. After that how such reactions takes place is discussed. Ionic bond formation is discussed. Such bond formation can be represented in two forms.
Electrons are loosed by metals and gained ncert science class 10th pdf generator non-metals. One get positively charged and another get negatively charged.
They get attracted and a strong bond is formed. The first one is electronic configuration. The bond genrrator is discussed through Bohr model.
Another method is Lewis structure or electron-dot structure. The metals and non-metals are written with their symbol and dots.
