Chemistry is one of the important branches of science that deals with the identification, structure, and reactions of the elements and compounds that make up our world. In 11th-grade chemistry, you have to learn about the basic principles of chemistr

Stoichiometry is the quantitative relation between the number of moles (and therefore mass) of various products and reactants in a chemical reaction. Chemical reactions must be balanced, or in other words, must have the same number of various atoms i

Redox is a type of chemical reaction in which the oxidation states of atoms are changed. Redox reactions are characterized by the actual or formal transfer of electrons between chemical species, most often with one species undergoing oxidation while

The force that holds different atoms in a molecule is called a chemical bond. A chemical bond is a lasting attraction between atoms, ions, or molecules that enables the formation of chemical compounds. In general, strong chemical bonding is associate

The periodic table arranges the elements by periodic properties, which are recurring trends in physical and chemical characteristics. These trends explain the periodicity observed in the elemental properties of atomic radius, ionization energy, elect

Anatomy, a field in the biological sciences concerned with the identification and description of the body structures of living things. Plant anatomy is the study of the shape, structure, and size of plants. As a part of botany, plant anatomy focuses

Morphology is the study of the size, shape, and structure of plants and microorganisms and of the relationships of their parts. The term refers to the general aspects of biological form and arrangement of the parts of a plant. The features that disti

The gaseous state features very small attractive forces between the gas particles, which are separated from each other by relatively greater distances when compared to liquids and solids. It is important to note that substances that exist in the gase

The structure of an atom is an atom consists of a nucleus and a number of electrons present around the nucleus. All the three charges have a mass value and the mass of protons and neutrons together gives the mass of the nucleus i.e. the atomic mass o

The mole was introduced as seventh base quantity for amount of substance. It is the SI unit of amt of substance. One mole contains 6.022×10²⁴ elementary entities. It is fixed numerical value of Avogadro Constant (NА). The amount of substance, symbol

The study of science has always fascinated me. It has always been of great significance. Our schools have been filled with science studies and we have heard how intriguing and fascinating it is. Science has given us much insight into one of the most

Undeniably, with advancements, we have seen how our lives have been improving. We must have heard of the elements in science? The elements and solids are known to balance the equations of chemistry equations. Magnesium, you all must be aware of, righ

Chemistry is a branch of science that involved elements and compounds composed of atoms, molecules, and ions and their composition, structure, properties, behavior, and the changes they undergo during a reaction with other substances. So take this qu

The last known chemical of Halogen group astatine was synthesized by Dale R. Corson, Kenneth Ross MacKenzie, and Emilio G. Segrè in the year 1940 at the University of California. The chemical is radioactive and highly unstable. The element can be pro

All the ingredients that we use in our daily life are made up of Elements. Moreover, all of us humans are also made up of the element. Must be surprised to hear that but it's true, the human body is primarily composed of six elements: oxygen, carbon,

When a reversible reaction is performed in a closed container or state is reached when the rate of forwarding and the backward reaction becomes equal. This state is called chemical equilibrium. Chemical equilibrium is part of physical chemistry. Take

Zero class elements are chemically inert. For this reason, these elements are called Inert gas or Noble Gases. Except for some gases, all other inert gases are found in the atmosphere. They are also called rare gases due to the rare receipt of inert
