The general formula for an oxide is AO, where A represents a metal and O represents oxygen.

Sulfur dioxide (SO2) is an acidic oxide because it reacts with water to form sulfurous acid (H2SO3).

Calcium oxide (CaO) is a basic oxide because it reacts with water to form calcium hydroxide (Ca(OH)2), a strong base.

Aluminum oxide (Al2O3) is amphoteric, meaning it can react with both acids and bases.

Chromium(III) oxide (Cr2O3) is commonly used as a rust inhibitor because it forms a protective layer on the surface of metal, preventing it from rusting.

Calcium oxide (CaO) is used in the production of cement because it reacts with silicon dioxide (SiO2) and aluminum oxide (Al2O3) to form calcium silicate and calcium aluminate, which are the main components of cement.

Sodium hypochlorite (NaClO) is commonly used as a bleaching agent because it is a strong oxidizing agent that can remove stains and kill bacteria.

Silicon dioxide (SiO2) is the main component of glass. It is mixed with other oxides, such as sodium oxide (Na2O) and calcium oxide (CaO), to create different types of glass.

Phosphorus pentoxide (P2O5) is commonly used as a fertilizer because it is a source of phosphorus, an essential nutrient for plant growth.

Iron(III) oxide (Fe2O3) is used in the production of steel because it is a source of iron, the main component of steel.

Carbon monoxide (CO) is commonly used as a fuel because it is a combustible gas that can be burned to produce heat.

Silicon dioxide (SiO2) is the main component of ceramics. It is mixed with other oxides, such as aluminum oxide (Al2O3) and calcium oxide (CaO), to create different types of ceramics.

Titanium dioxide (TiO2) is commonly used as a pigment because it is a white, opaque powder that can be used to create a variety of colors.

Gallium arsenide (GaAs) is commonly used in the production of semiconductors because it is a compound semiconductor with a wide bandgap and high electron mobility.

Vanadium(V) oxide (V2O5) is commonly used as a catalyst because it is a highly active and selective catalyst for a variety of reactions.
