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.
