Introduction
In the chapter on current electricity, we had learnt about the flow of charges, conditions to produce the flow and how different materials respond to an external electric field. We had seen how materials are classified as conductors and insulators. In this chapter, we will study..
Method of substitution:
If the integrand f(x) of the integral is not in an integral form the variable of integration x is changed to a suitable variable z by substitution and on differentiation and simplification, the new integral is found integrable. ..

Now, if the concentration of [B] o and [C] o are kept constant, then the initial rate (new) is Now, this new initial rate is measured for two different initial concentrations of A, that is, [A o ] 1 , [A o ] 2 such that Now the value of m can be obtained by dividing equation ( )..

Assume, we start with a volume of 273 litres of a gas at 32 o F. Cool it to 30.2 o F. It will lose 1/ 273 of the original volume at 32 o F. So the new volume at 30.2 o F = (273 -1) = 273 lt Cool it further to 28.4 o F. New volume at 28.4 o F = (272 -1) = 271 lt In other wor..

A radioactive nucleus or element emits an alpha or a beta particle and gets converted into a new nucleus or element. The process of destruction of the original nucleus during the formation of new nucleus due to radioactivity is called Radioactive decay or disintegration. When..

The numerical value of equilibrium constant depends upon the stoichiometry of the chemical equation used in representing the reaction. For example, the reaction can also be expressed as Then, the corresponding equilibrium constants are When the coefficients are doubled, then the K for th..

She should be the head of Tutor Vista. She knows how to treat her students. Her teaching style is spectacular.
Best tutor ever. I can actually understand what to do in fraction and decimal division situations
This Tutor Vista is GREAT! loved this session, it helped me heaps.
Terific helped showed how to apply formulas i will study these examples to go further--much gratitude--will come back again ThankYou
