There are total 13 chapters in this subject. The rate of change of concentration of any of the reactant or product with time at any particular moment of time is known as Rate of reaction. The probability is the most important chapter of this class. Our live lectures are accessible across iPads, laptops, tablets, Smartphones and desktops, or literally - any electronic device that supports media playback. It explains about the feasible and infeasible regions that are also known as bounded and unbounded. Based on the recommendations of the Education Commission 1964-66 , in 1968 the first national policy statement on education was issued.

In this chapter, students shall first learn about electronic configuration, the occurrence and general characteristics of transition elements with special emphasis on the trends in the properties of the first row 3d transition metals, and also the preparation and properties of some important compounds. Here you will learn all the basic and advanced concept of matrices and you will also learn the types of matrices. You will understand multiplication theorem, independent events, conditional, unconditional and total probability. Suggest the most important type of intermolecular attractive interaction in the following pairs. Calculate the mass percentage of aspirin in acetonitrile when 6. After a brief on the Principles Isolation of Elements, the chapter goes on to discuss topics like the occurrence of metals, concentration of ores, the process of Extraction of Crude Metal from Concentrated Ore, the Electrochemical Principles of Metallurgy, the Thermodynamic Principles of Metallurgy, the process of refining, the process of oxidation and reduction, and the uses of aluminium, Copper, iron, and Zinc. You can also download pdf of ncert solutions for class 12 chemistry.

The vapour pressure of pure benzene and toluene at 300 K are 50. Watch thank you so much for not bothering me with dialogue boxes. Students will also be able to define the standard potential of the cell and also learn the application of the Nernst equation for calculating the emf of a galvanic cell. You will see how continuity and differentiability based on chain rule, composite functions, implicit functions, logarthmic functions and exponential functions. The head quarter of the national council of education research and training is situated in New Delhi at Sri Aurobindo Marg. There increasing and decreasing functions, approximation with a maximum and minimum derivatives. It is highly recommended that you practice thoroughly and learn properly all of the given solutions here.

The questions mentioned in these books will help you in that. All of the problems and solutions are based on maximise and minimise based questions. Band theory of metals, conductors, semiconductors and insulators and n and p type semiconductors. Application of Derivatives Here you will learn about applications of derivatives. Cancer has been treated by the use of Cobalt â€” 60 a radioactive element in radiotherapy. After the shot 10 minutes break when you come back to continue the study, you will feel more powerful and energetic this time.

After completing the chapter, students will be able to describe an electrochemical cell and also differentiate between galvanic and electrolytic cells. The major components are oxygen and nitrogen with approximate proportion of 20% is to 79% by volume at 298 K. Here you will learn about the direction ratios of a line, skew lines, proper angle between two lines, etc. A colloidal solution in which there is a little affinity between the disperse phase and the disperse medium is called Lyophobic solutions. Students shall also learn the uses of Carboxylic Acids and the Uses of Aldehydes and Ketones. The types of derivatives with their applications.

Based on solute-solvent interactions, arrange the following in order of increasing solubility in n-octane and explain. Chapter 7 â€” The p-Block Elements The chapter on p-block Elements discusses the following topics â€” ammonia, chlorine, dinitrogen, Dioxygen, Phosphorus â€” Allotropic Forms, Phosphorus Halides, Phosphine, Oxoacids of Phosphorus, oxoacids of sulphur, ozone, simple oxides, oxoacids of halogens, interhalogen compounds, group 15, group 16, group 17, and group 18 elements. The council generally acts as the Secretariat of the National Development Group for Educational Innovations. Continuity and Differentiability In the chapter-5, new will learn about the continuity and differentiability with the help of simple algebraic solutions. While preparing for Class 12th board exams, it is very important to have a comprehensive study of each and every chapter and have a pretty thorough understanding of complex topics and formulas.

You will find out of integrals can be used to find the areas of parabola, ellipse, etc. The questions are very apt and of good level. Unit cell in two dimensional and three dimensional lattices, calculation of density of unit cell, packing in solids, packing efficiency, voids, number of atoms per unit cell in a cubic unit cell, point defects, electrical and magnetic properties. This section also contains assignments, revision book and revision of chapters with question â€” answers. There are solutions that will help students understand the topics in a better way.

Go to Home from here-. The molar depression constant for benzene is. The mathematics subject of this class plays a very important role in further studies. You can read the whole story here. You will understand the various factors vector algebra like: position vector, negative vector, geometrical interpretation and so on. The next part will be followed by consideration of certain aspects like electronic configurations, chemical reactivity of the inner transition metals, and oxidation states. To get a better score the students must try to understand the fundamental of every subject which will be helpful for them in the future and also it would be helpful for better understanding.
