2020/8/18· Calcium oxide is a basic oxide and reacts with acidic oxides such as silicon dioxide present in the rock. Calcium oxide reacts with silicon dioxide to give calcium silie. The calcium silie melts and runs down through the furnace to form a layer on top of the molten iron.
Chemistry: The Central Science, Chapter 4, Section 4
Many metals react directly with O 2 in air to form metal oxides. In these reactions the metal loses electrons to oxygen, forming an ionic compound of the metal ion and oxide ion. For example, when calcium metal is exposed to air, the bright metallic surface of the metal tarnishes as CaO forms:

Oxygen can react with metals and non - metals to form compounds which contain oxygen and another element of metal or non-metal. Oxides can be divided into four types. Many elements get oxidized in air or water naturally. This is the reason many oxides are
Metals and Nonmetals Class 10 Notes - CBSE CLASS 10 …
Metals Reaction with oxygen in Air Almost all metals coine with oxygen to form metal oxides. Metal + Oxygen → Metal oxide This is because it reacts with sulphur in the air to form a coating of silver sulphide. Copper reacts with moist carbon dioxide in
T9: Metals, the Reactivity Series and Redox Reactions
The other metals above hydrogen in the series react with steam, to form the metal oxide and hydrogen: Zn + H2O ( ZnO + H2 With acids - Metals above hydrogen will react to form metal salts and hydrogen (K, Na and Ca are too reactive to test).

Metal, Non-metal and Metalloid Oxides (also called Anhydrides)
(also called Anhydrides) Metal oxides act as BASES in aqueous solution. Group 1 and Group 2 Oxides are ionic. They dissociate to form the oxide ion (O2-) Eg. Na2O (s) ( 2 Na+(aq) + O2-(aq) The oxide ( O2- ) ion then undergoes 100% hydrolysis
Types of Oxides | A* Chemistry
Most oxides can be grouped into four types: acidic oxides, basic oxides, amphoteric oxides, and neutral oxides. Acidic Oxides: Non-metals may form acidic oxides. Most acidic oxides dissolve in water to form an acid. These oxides do not react with acids
