An oxide is a compound of oxygen and one or more other elements.Examples of oxides are carbon dioxide, CO2, sulfur trioxide, SO3, and sodium oxide, Na2O.
An oxide formed by a non-metal and oxygen is called a non-metal oxide.Some examples are:
CO2
NO2
Cl2O
Metal oxides, and non-metal oxides have quite different properties.One very important difference is what they produce when they are dissolved in water.

Vehicle exhaust releases nitrogen oxides like NO2 to the atomosphere.
Acid precipitation can have serious effects on freshwater organisms, crops, and forests.Acid precipitation can also damage buildings and statues made of limestone or marble.
Limestone and marble are made up of calcium carbonate, CaCO3(s). When calcium carbonate is exposed to sulfuric acid (H2SO4(aq)), the following reaction occurs:
