The program was renamed to National Talent Search Scheme with the NTSE examination now being conducted for classes X, XI, and XII. Currently, the NTSE exam is conducted only for 10th class students in India in two phases with subjects relating to Mental Ability Test and Scholastic Aptitude Test (SAT) for 100 marks each. [6] [7]
Central Board of Secondary Education expression series is an online/offline essay/poem/drawing competition organised by the Central Board of Secondary Education (CBSE) in India for classes 1 to 12.

On obtaining this certificate, the student is deemed to have completed secondary schooling. After successful completion of SSLC, Students will further pursue their higher secondary education i.e. Class 11th and Class 12th by either attending a Junior College or by continuing High School in one of three streams – Science, Commerce or Arts.
Antoine Lavoisier publishes Traité Élémentaire de Chimie, the first modern chemistry textbook. It is a complete survey of (at that time) modern chemistry, including the first concise definition of the law of conservation of mass, and thus also represents the founding of the discipline of stoichiometry or quantitative chemical analysis. [42 ...
Intrinsic properties are dependent mainly on the fundamental chemical composition and structure of the material. [1] Extrinsic properties are differentiated as being dependent on the presence of avoidable chemical contaminants or structural defects.
The 'rule of thumb' that the rate of chemical reactions doubles for every 10 °C temperature rise is a common misconception. This may have been generalized from the special case of biological systems, where the α (temperature coefficient) is often between 1.5 and 2.5. The kinetics of rapid reactions can be studied with the temperature jump method.
Much of chemistry research is focused on the synthesis and characterization of beneficial products, as well as the detection and removal of undesirable products. Synthetic chemists can be subdivided into research chemists who design new chemicals and pioneer new methods for synthesizing chemicals, as well as process chemists who scale up chemical production and make it safer, more ...
