Q. Explain about Conservation of Mass?
Conservation of Mass above two centuries ago chemists established a fundamental law called the law of conservation of mass.
This law states that throughout a chemical reaction mass is neither lost nor gained. In other sense all the matter present at the start of a reaction still exists at the end of the reaction. The law of conservation of mass is able to be stated in mathematical form as follows
Mass reactants = Mass products
Coordination number and geometry Binary compounds are ones with two different elements present. 'Simple' crystal structures can be classed as ones in which each atom (or
Explain the process of Grading and Sieving Grading: Grading consists of separating the sound kernels from chaff and impurities,and may be achieved by sieving or winnowing.
