What Happens During a Chemical Reaction?
During a Chemical Reaction, the fundamental units, which are the atoms of the participating molecules or elements, undergo rearrangement to create new molecules. This rearrangement involves the rupture of existing chemical bonds between atoms and this process absorbs energy, and the establishment of new chemical bonds, which results in the release of energy.
Physical Changes During a Chemical Reactions
A Physical Change is the change in the physical properties of a substance. These changes are frequently observed in the course of chemical reactions, yet they do not transform the fundamental nature of the substances involved. Typically, physical changes manifest in modifications such as change in colour, the development of odours, or the release of gases. It’s important to note that the occurrence of physical changes does not necessarily entail the presence of chemical reactions.
Chemical Reactions
Chemical Reaction is the disruption of existing bonds within reactant molecules and the creation of fresh bonds in product molecules, culminating in the formation of a new substance. These reactions are all around us, spanning from the biochemical processes in our bodies that extract energy from food to the source of sunlight, where chemical reactions are used to produce the light we receive.
In this article, we will understand the meaning and characteristics of Chemical Reactions. This article will cover the various types of Chemical Reactions: Combination or Synthesis Reaction, Decomposition Reaction, Single Displacement Reaction, and Double Displacement Reaction. We also discuss factors affecting the rate of Reaction and practice questions to understand this article.
