When we cut onions

When we cut onions, two cells present in them are released: one rich in sulphides and the other in enzymes

When these cells mix, a reaction occurs that produces an acid called sulfenic acid. This acid is transformed into gas and, when in contact with water, generates a weak solution of sulfuric acid. As the eyes are always wet, the solution formed causes irritation in the eyes, which causes tears. That's why we cry when we cut onions.

Explore more about The Fall of the Roman Empire in 476 AD is one of the most significant milestones in history, representing the end of Antiquity and the beginning of the Middle Ages. The Empire, which once controlled vast areas of Europe, North Africa and Western Asia, declined due to a combination of factors that weakened its structure.
Internally, the empire faced political instability, with frequent changes of emperors and widespread administrative corruption. Government inefficiency and growing social inequality also contributed to its collapse. In addition, difficulties in maintaining the borders and military pressure further weakened the Roman structure. Externally, barbarian invaders such as the Visigoths, Vandals and Ostrogoths repeatedly attacked the Roman borders. The sack of Rome by Alaric in 410 AD and the invasion of the Vandals in 455 AD were decisive events, culminating in the deposition of the last Roman emperor, Romulus Augustulus, by Odoacer in 476 AD.
After its fall, the Western Roman Empire was fragmented, giving rise to barbarian kingdoms such as the Franks and Visigoths. Although the period has been called the Dark Ages, it was also an era of important transformations. With its capital in Constantinople, it survived until 1453, profoundly changing the politics and social organization of the Western world...
