Overview of Chemistry Terms The scientific study of matter's characteristics and behaviour is known as chemistry. Chemistry vocabulary and Chemistry glossary are different from the normal vocabulary. It is a branch of natural science that examines the building blocks of matter, including the atoms, m...
What is a pure substance in chemistry? What are significant figures in analytical chemistry? What is mu in physical chemistry? What is physical organic chemistry? What is conductivity in analytical chemistry? What is metamerism in chemistry?
The study of chemistry has allowed scientists to craft stronger metals, brew potent rocket fuels, and even create new medicines. There are just over one hundred elements (types of atoms) that combine to form all of the materials in our world, from the air we breathe to the bombs we build...
More importantly, this aspect of chemistry controls the direction in which change occurs, and the mixture of substances that results. Composition and structure define the substances that are results of chemical change. Structure refers specifically to the relative arrangements of the atoms in space. ...
This article presents a personal answer to the question “What is chemistry?”, set out in terms of six propositions. These cover “pureR
No substances can be called“chemical-free”. Indeed,“natural”chemicals do not always have advantages. Some of the most dangerous poisons known are natural chemicals, produced by bacterial and other living things. Modern chemistry is devoted to understanding the chemical structures and properties of...
The double definition of elements proposed by the International Union for Pure and Applied Chemistry contrasts an abstract meaning and an operational one. Nevertheless, the philosophical aspects of this notion are not fully captured by the IUPAC definitions, despite the fact that they were crucial ...
Nitrogen is an odorless, colorless gas symbolized by the letter N on the periodic table. Nitrogen has a wide range of uses, ranging from medical research to food packaging. All commercially obtained chemicals are really mixtures, though highly pure chemicals contain only very minute quantities of ...
