Chemistry. The tables in this chapter contain information about chemicals, elements, materials, and reactions. In the back of the Binas, there is a periodic table. Biology. This chapter contains tables about general concepts of biology, such as: DNA, cells, circulatory system of the human body, reproduction, etc.
Chemistry is the scientific study of the properties and behavior of matter. [1] It is a physical science within the natural sciences that studies the chemical elements that make up matter and compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during reactions with other substances.
is an alkaline solution of potassium permanganate; used in organic chemistry as a qualitative test for the presence of unsaturation, such as double bonds; N-Bromosuccinimide: used in radical substitution and electrophilic addition reactions in organic chemistry. Also acts as a mild oxidizer to oxidize benzylic or allylic alcohols.
In solution chemistry and biochemistry, the Gibbs free energy decrease (∂G/∂ξ, in molar units, denoted cryptically by ΔG) is commonly used as a surrogate for (−T times) the global entropy produced by spontaneous chemical reactions in situations where no work is being done; or at least no "useful" work; i.e., other than perhaps ± P dV.
On 12 April 2018, the police said that Rakesh Kumar, who leaked the class 12 economics paper, had leaked class 10 mathematics paper also. [40] Consequently, the Central Board of Secondary Education has put in place a system of "encrypted" question papers, which are supposed to be printed by the schools half an hour before the exam starts.
The team for the International Physics Olympiad is selected based on a rigorous procedure of theory and practical examinations (Normally, 3 each) at OCSC Physics.60% (240 marks) weightage is given to the theory exam, and 40% (160 marks) to the practical one, akin to that at the International Physics Olympiad. The difficulty level is similar to ...
