Are non metal oxides solid?

Non-metals react with oxygen in the air to produce non-metal oxides. Here are two examples for the non-metals carbon and sulphur. Non-metal oxides such as sulphur dioxide and nitrogen oxide are responsible for acid rain. They dissolve in the water in the clouds to form acidic solutions.

Simply so, are all metal oxides bases?

Metal oxides and metal hydroxides are two types of bases. For example copper oxide and sodium hydroxide. Here are general word equations for what happens in their neutralisation reactions with acids. The mixture usually warms up a little during the reaction, too.

What is an oxide of a metal?

An oxide /ˈ?ksa?d/ is a chemical compound that contains at least one oxygen atom and one other element in its chemical formula. "Oxide" itself is the dianion of oxygen, an O2 atom. Metal oxides thus typically contain an anion of oxygen in the oxidation state of −2.

Is a metal oxide a salt?

A few metal oxides like ZnO and Al2O3 are amphoteric, which means they can react with both acids and alkalies to form a salt and water. So no, metal oxides are not salts. They are usually basic and may react with an acid to form a salt.
