Hydrogen is a peculiar element in nature, resembling halogens and alkali metals. The preparation of hydrogen gas involves several processes. The various methods for the preparation of hydrogen are as follows: 1. From acid: The metals that are more electropositive than hydrogen, such … Read more
Chemical equations can be written in a variety of ways. Unbalanced equations, which indicate the species involved; balanced chemical equations, which indicate the number and type of species; molecular equations, which express compounds as molecules rather than component ions; and … Read more
Visually tracking physical changes and chemical reactions can be done well with chemical reaction equations. However, we must first understand how to properly do representation of chemical reactions before we can evaluate these equations to see these changes. To put … Read more
J Heyrovsky’s innovated polarography, in which a falling mercury electrode is utilized in an electrochemical cell, revolutionized electroanalysis, electrode kinetics research, and adsorption investigations on mercury electrodes. Additionally, polarography has directly influenced the creation of novel and creative concepts in … Read more
Valence Shell Electron Pair Repulsion (VSEPR) Theory is a basic theory that predicts and explains the shape and bond angles of various molecules and ions with simple covalent bonds. This theory was proposed by Sedgwick and Powell initially in 1940 and developed … Read more
Ecotoxicology combines elements of ecology, toxicology, physiology, analytical chemistry, molecular biology, and mathematics. Ecotoxicology studies how pollutants, such as pesticides, affect people, populations, the environment, and ecosystems. Ecosystems are made up of groups of living beings and the habitats they … Read more
The important component of nanoscience and nanotechnology is the synthesis of nanomaterials and nanostructures. New physical properties and applications of nanomaterials are only achievable when nanostructured materials of the necessary size, shape, morphology, crystal structure, and chemical composition are made … Read more
Liquid crystals (LCs) are a kind of matter that exists between crystalline solids, which have a regular periodic arrangement of atoms or molecules, and isotropic liquids, which have no order.The study of liquid crystals began in 1888, when an Austrian … Read more
Metal ores are scarce on Earth. They can’t be replenished if we use them all up. There is a finite quantity of metal ores on Earth. Things made from metals and other materials from the Earth’s crust are frequently discarded. … Read more
