Combustion of Hydrocarbons:
Originally observed by Antoine Lavoisier, combustion reactions are fundamental to energy generation and transportation.
Haber Process:
Developed by Fritz Haber in the early 20th century, this reaction synthesizes ammonia for fertilizer, crucial for modern agriculture.
Photosynthesis:
Discovered through the work of many scientists over time, photosynthesis is the process by which plants produce oxygen and glucose.
Rusting of Iron:
Rusting, or oxidation, of iron was understood over time as the chemical reaction with oxygen and water, impacting industries and infrastructure.
Combustion of Gunpowder:
Gunpowder, discovered in ancient China, led to the creation of firearms and had a profound impact on warfare and geopolitics.
Saponification, Soap Making:
An ancient reaction, known to Babylonians, where fats are turned into soap and glycerol, significantly advancing hygiene and health.
Fermentation of Ethanol:
Utilized since ancient times for producing alcoholic beverages and bread, fermentation is a biological process with various industrial applications today.
Electrolysis of Water:
First performed by William Nicholson and Anthony Carlisle in 1800, it's the decomposition of water into oxygen and hydrogen gas using electricity.
Baking Soda and Vinegar Reaction:
A common household reaction, producing carbon dioxide and demonstrating the neutralization of an acid by a base.
Discovery of Oxygen:
Joseph Priestley discovered oxygen in 1774 through the thermal decomposition of mercuric oxide, which altered the understanding of combustion.
Ozone Layer Formation:
Formation of the ozone layer is vital for protecting life from the sun's harmful UV radiation, naturally occurring in the high atmosphere.
Neutralization Reaction:
A foundational chemical reaction in acid-base chemistry, extending from practical applications like antacids to general pH control.
Synthesis of Aspirin:
First synthesized by Felix Hoffmann at Bayer in 1897, aspirin is one of the most widely used medications globally for pain and fever.
Contact Process:
Developed in the 19th century, this reaction facilitates the production of sulfuric acid, an essential industrial chemical.
Penicillin Production:
Alexander Fleming's accidental discovery of penicillin in 1928 revolutionized medicine by introducing antibiotics to treat bacterial infections.
