What Is Chemical Change?

[wordads]

What Is Chemical Change?:- Chemical changes occur when a substance mixes with two or more different substances to form a new thing, called chemical synthesis, or chemical decomposition into different compositions. This synthesis or decomposition process is referred to as chemical reactions and is generally irreversible but by additional chemical retreats, it can be reversed. There are two categories of chemical reactions, one is an exothermic reaction and the other is an endothermic reaction. When heat is released from the reaction then it is called an exothermic reaction. Whereas endothermic reaction requires heat for completion of it. Comprehension of chemical changes is an important part of chemical science.

Definition:- When there are chemical reactions, atoms are reordered and energy difference follows the reaction when new outputs are produced.

The iron metal reacts with oxygen in the atmosphere to form a new compound, which we called as iron oxide (rusts). The following simple chemical equation can show this chemical reaction:
Iron(Fe) plus Oxygen(O) reacts to form Iron-Oxide(FeO)
Fe + O → FeO

This illustrates the chemical change, as the result products differ chemically from the materials before the reaction.

Evidence of a chemical change

These are some indicators for identification of chemical change:

Change in color– A color change is a good indicator that a chemical reaction has occurred. Reactions involving transition metals are particularly likely to produce colors (for example, silver to reddish-brown when iron rusts).

Change in odor- A reaction may release a volatile chemical that produces a characteristic scent.

Formation of gases, often appearing as bubbles– Some chemical changes produce gases, which can be seen as bubbles in a liquid solution.

Changes in temperature or energy– Because there is an energy change in a chemical reaction, therefore a measurable temperature change also occurs.

Change in composition – When combustion occurs, for example, it produces ash and this leads to change in composition.

The change is difficult or impossible to reverse– Chemical changes are often difficult or impossible to reverse.

The decomposition of organic matter– substance break down into two or more elements, called breakdown of matter.

Light and/or heat given off– Some chemical reactions produce light/heat when undergoes a chemical reaction.

Formation of a precipitate (insoluble particles)– Some chemical reactions produce solid particles that may remain suspended in a solution or fall out as a precipitate.

Types

Chemical changes have three main divisions:

Inorganic changes

Inorganic chemistry describes the reactions of components and mixtures which are generally carbon-free. These type of changes usually occur in labs or in massive industries on a large scale. These type of changes includes neutralization (mixing of acid into a base, leading to water and salt), oxidation and redox reactions.

Organic changes

Organic chemistry focuses on the chemical substances of carbon and its compounds. These composites include oils and all of its products and a large part of pharmaceutical, paint, detergent, cosmetical, fuel, etc. Organic chemical changes typically include breaking complex hydrocarbons in the oil-producing refinery to produce petrol from the raw oil, as petrol is more demanding than complex hydrocarbons.

Biochemical change

Biochemistry focuses on the chemistry of living creature’s growth and activities. In Biological chemistry, most of the reactions are managed by complex enzymes and restricted by hormones. This Chemistry is always extremely complex and not yet fully accepted. The biochemistry also includes decomposition of the organic material even though the fungi, bacteria and viruses and other micro-organisms grow and work in this case. Chemical changes included in biochemical changes include photosynthesis process, digestion process, protein synthesis process, and many more.
