In previous classes, students were introduced to physical and chemical changes. The chemical changes signify the chemical reactions. The indicators of chemical reactions are explained with some indicators like change in physical state, change in color, Ncert 10th Class Science Question Paper Ncert Question 10th Class Science Paper change in temperature and evolution of gas. These are explained with some experimental examples. After that writing of chemical equation has been explained.
It is symbolic representation of chemical reactions. Also, Ncert 10th Class Science Question Paper it has been explained that how such equations can 10h more informative. For example, balancing a chemical equation will signify that the chemical reactions follow law of ncert 10th Ncert 10th Class Science Question Paper class science question paper of mass. Other information like physical states and conditions required for Ncert 10th Class Science Question Paper 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 Ncert 10th Class Science Question Paper basis of energy, exothermic and endothermic reactions are mentioned. Redox reactions are explained which Ncert 10th Class Science Question Paper are combination of reduction reaction and oxidation reaction.
All types of reactions are explained with Ncert 10th Class Science Question Paper 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 Ncert 10th Class Science Question Paper in taste and ncert 10th class science question paper blue litmus red.
Examples of acids are sour fruits like, Bases are defined as substances which are bitter in taste and turns red litmus blue.
Examples ncert 10th class science question paper bases are neem, clove, 10th Ncert Question Science Class Paper vinegar. Here, acids and bases are defined chemically. Bases are chemically those substances which Ncert 10th Class Science Question Paper generate OH- ions in aqueous solutionIf not they are weak acids. After that, various chemical Ncert 10th Class Science Question Paper and olfactory indicators are discussed; this indicates the 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, Quextion ncert 10th class science question paper is a chemical indicator. It turns red in acidic solution and yellow in basic solution. Olfactory indicators Ncert 10th Class Science Question Paper are indicators which changes odor after coming in contact with acid and base. For example, smell of clove vanishes when kept in contact with acid.
After that acids and Ncert 10th Class Science Question Paper bases reactions are discussed 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. Universal 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 are used Ncert 10th Class Science Question Paper for various process. Their formation and uses are explained in this chapter. Chapter 3 - Ncert 10th class science question paper and Non-Metals The chapter starts with physical properties ncert 10th class science question paper metals and non-metals.
The parameters discussed are some physical properties, Ncert 10th Class Science Question Paper Ncert 10th Class Science Question Paper like melting and boiling points, physical state at room temperature, ductility, sdience, tensile strength. The Ncert 10th Class Science Question Paper metals and non �metals questikn 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. Paer is metal but liquid at room temperature. There are more such exceptions. Therefore, classification of clwss and non-metals, are based on chemical properties. Chemical reactions of Ncert 10th Class Science Question Paper metals with oxygen gas, water, acids and other metal salts are discussed.
The reactions and Ncert 10th Class Science Question Paper their condition depends upon the reactivity series. The metals on top of reactivity series are sodium and Potassium. They perform vigorous reactions. Nature of metallic oxides is discussed. Generally Metal Ncert 10th Class Science Question Paper oxides are basic in nature.
