The sun is known as the greatest provider of energy to earth. The main two main forms of energy produced by the sun are heat and light energy. For many years, scientists were puzzled by the working mechanism of the sun. Questions were asked regarding how the sun produces the vast amount of heat and light energy that supports and indeed sustains the life on earth. Scientists and experts in various fields of study provided different theories about the production of heat and energy by the sun and some even clashed with each other. For example, there were constant Continue reading...

Sun is an important heavenly body that exists in the solar system. Because of its existence, other planets and stars are moving appropriately in their orbits. The sun produces a large quantity of heat and light which is a source of energy for other planets including the Earth. Scientists have worked upon for so many years upon the working of the Sun. how does the sun produce light and heat. How does the sun produce light and heat? How does it provide energy?
The sun is a combination of an ample of gasses, which when combined results in various Continue reading...

Back titration of Calcium Carbonate with Sodium Hydroxide.

Introduction
Here the amount of Calcium Carbonate is asked and because it is an insoluble salt "back titration" is used. Titration is a method which it's another name is volumetric method, in this method a reactant is used to bring a reaction to endpoint. In this method, one sample (unknown) value is determined by a standard (known) value.
But "back titration" is needed because here Calcium Carbonate is an insoluble salt and it's not possible to calculate its amount by direct titration.
In this experiment first calcium carbonate was reacted with an excess known hydrochloric acid and the unreacted Continue reading...

Introduction

Atoms are those constituents of all the matters which are the smallest. Atoms are the main part of the element and the different elements have different atoms. Atoms also contain the sub-atomic particles. Among these sub-atomic particles, the three particles hold the significant importance and therefore are studied more. These sub-atomic particles includes proton, neutron and electron. The elements that are different possess different atoms in terms of difference in the number of these sub-atomic particles. Consequently, the number of subatomic particles in an atom is the basis for the characterization of the atoms elements containing the atoms. Most Continue reading...
