The intake of various nutrients present in food for the development, actions, protection of the body from diseases, and for the fulfillment of physical needs is known as nutrition. It plays a very important role in our lifestyle. If someone…
The term “stoichiometry” is derived from two Greek words – stoicheion (meaning, element) and metron (meaning, measure). It is a branch of chemistry that deals with the quantitative relationships between reactants and products involved in a chemical reaction. Stoichiometry in…
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…
Definition of chemical equation: 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…
What is molecular formula | 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…
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, percentage composition is the mass percentage of each component element present in any compound. The percentage composition (or mass percentage) of each element is equal to the mass of that element divided by the total mass present in…
We commonly use a unit dozen or unit gross for counting of materials or goods. For example, one dozen pens means 12 pens or one dozen bananas means 12 bananas. Similarly, one gross books means 144 books or one gross…
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…
