What is Chemical reaction and also tell it's characteristics.
Answers
A chemical reaction is a process that leads to the chemical transformation of one set of chemical substances to another.[1] Classically, chemical reactions encompass changes that only involve the positions of electrons in the forming and breaking of chemical bonds between atoms, with no change to the nuclei (no change to the elements present), and can often be described by a chemical equation. Nuclear chemistry is a sub-discipline of chemistry that involves the chemical reactions of unstable and radioactive elements where both electronic and nuclear changes can occur.
characteristic
A chemical reaction results in a change of molecular or ionic structure. Scientists and medical professionals create and observe chemical reactions in order to study these changes. But how do they know whether a chemical reaction has taken place during the course of an experiment? The only way to know for sure is to perform a detailed chemical analysis. However, chemical reactions have several observable characteristics that scientists can see. The presence of one or more of these characteristics may indicate that a chemical reaction has taken place.
