The fourth quadrant also has Frequently Asked Questions (FAQs) and their answers to clarify common misconceptions among students. [ 10 ] The University Grants Commission (UGC) considers that universities should play a key role in publicizing and popularizing SWAYAM courses among their learners and the university, enabling them to gain from ...

A mnemonic is a memory aid used to improve long-term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics.
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.
Traité Élémentaire de Chimie (Elementary Treatise of Chemistry) - Antoine Lavoisier; Traité Élémentaire de Chimie, 1789, available in English as Elementary Treatise of Chemistry; Description: This book was intended as an introduction to new theories in chemistry and as such, was one of the first Chemistry textbooks. [9]
Science is a universal subject that spans the branch of knowledge that examines the structure and behavior of the physical and natural world through observation and experiment. [9] Science education is most commonly broken down into the following three fields: Biology, chemistry, and physics.
All carbon atoms have 6 protons, but they can have either 6, 7, or 8 neutrons. Since the mass numbers of these are 12, 13 and 14 respectively, said three isotopes are known as carbon-12, carbon-13, and carbon-14 (12 C, 13 C, and 14 C). Natural carbon is a mixture of 12 C (about 98.9%), 13 C (about 1.1%) and about 1 atom per trillion of 14 C.
Free energy is subject to irreversible loss in the course of such work. [1] Since first-law energy is always conserved, it is evident that free energy is an expendable, second-law kind of energy. Several free energy functions may be formulated based on system criteria. Free energy functions are Legendre transforms of the internal energy.
