Chemical Reaction

1

CONDENSATION reaction is one in which two molecules combine to form a larger molecule with the loss of a small molecule. The small molecule lost is usually water, but not always. It can be considered to be the opposite of hydrolysis.

H₂SO₄ + H₂O → H₂O + HSO₄

HYDROLYSIS reaction involves the breaking of chemical bonds by the addition of water to a substance. In some cases, this addition can cause both the substance and the water molecule to split into two parts.

Mg + 2H₂O → Mg(OH)₂ +H₂

DISPLACEMENT reaction occurs when an element or ion moves out of one compound into another. It is usually occurs if the element moving into the compound is more reactive than element it displaces.

Fe₂O₃ +3CO → 2Fe + 3CO₂

_{REDUCTION reactions are sometimes defined as reactions in which other elements lose oxygen atoms. Generally, reduction can be defined as a reaction in which atoms of an element gain electrons.}
