When the number of atoms of each element on both sides of the arrow in a chemical equation is equal, it is called balanced chemical equation. This is because no matter is created or destroyed during a chemical reaction according…
In chemistry, a chemical equation is a way of representing a chemical reaction with the help of their chemical formulae and symbols. In other words, a chemical equation is a symbolic representation of a chemical change or reaction. When a…
A molecule is a smallest unit of a substance which exists independently and exhibits all the properties of that substance. We can represent a molecule by a formula in the terms of symbols and the number of atoms of elements…
In chemistry, a chemical formula is a group of symbols of the same or different elements which represents one molecule of the substance. It basically represents chemical composition of the substance. There are three types of formulae in the case…
In chemistry, a chemical formula is a shorthand way of describing a chemical compound, or a molecule with the help of symbols and valency of elements. It is one of the fundamental aspects of chemistry. In other words, a chemical…
In chemistry, molecular mass is an important property of molecules that are concerned with their physical and chemical properties. It is a measure of the total mass of all the atoms in a molecule. Understanding molecular mass is an important…
As we know that atoms of all elements are extremely small. We cannot see them either by the naked eye or even by the powerful microscope. Absolute (or actual) masses of atoms of elements are very, very small. Therefore, it…
Molecules are essential building blocks of everything around us. They are tiny particles that comprise atoms bonded together in a specific way. Molecules are the foundation of all living things and non-living things. Understanding what a molecule is and how…
In accordance with Dalton’s atomic theory, atoms of distinct elements react with each other in the simple ratios. Gay-Lussac proposed that gases react with each other in the simple ratio of their volumes, provided all gases are at the same…
In 1808, An English scientist John Dalton proposed the first scientific theory of matter. This theory is also known as Dalton’s atomic theory of matter. This atomic theory is mainly based on the laws of chemical combination. Postulates of Dalton’s…
