MOLECULAR FORMULA DEFINITION
A formula which tells the actual number of atoms present in a molecule of a substance is known as molecular formula.
Examples: H2O2 and C6H12O6 are the molecular formulas of hydrogen peroxide and glucose respectively.

The study of relationship between the amounts of reactants and products as indicated by the balanced chemical equation is called stoichiometry. Explanation: Stoichiometry is used to calculate the amount of the product formed or that of the reactant required in a reaction. Stoichiometric calculations are performed by the following assumptions in hand: Reactants are completely…
Analytical Chemistry is a branch of chemistry, which deals with the identification and quantification of chemical substances. It plays a vital role in almost all chemical sub-disciplines and is often the subject of current public discussions, for example, in environmental analysis. Types of Analytical Chemistry There are three main types of analytical Chemistry analysis: The…
Dimensional analysis in Chemistry is often a tricky concept for students to get. Still, it is a significant one and one that you will use throughout all of your chemistry classes. Dimensional analysis is the process we use to convert a value from one unit or set of units to another. Some important questions to…
The associate degree (AD) in Chemistry, equivalent to the European level 5, is a two-year higher professional education between the four-year MBO (level 4) and the four-year HBO bachelor (level 6). Many people think a four-year bachelor’s degree is far too long, especially if you want to do it part-time, you are vulnerable, because work,…
The lower density of ice than liquid water at 0°C compels water in ponds and lakes to freeze from surface to the downward direction. Water attains the temperature of 4°C by the fall of temperature in the surrounding. As the outer atmosphere becomes further cold, the water at the surface becomes less dense. This less…
Behavior of all the gases is similar to each other. To explain the similar behavior of all the gases, a model was devised. This model is known as kinetic molecular theory of gases. Main Postulates: The postulates of this theory are: Gases are made up of molecules, which are far apart from each other. Spaces…
