What are metal oxides with examples?
Metal oxides are oxides of metal. They are ionic in nature and form basic oxides. Eg: Na2O, MgO,etc
Is metal oxide is a base?
Yes, certain metal oxides, mostly from the middle groups of the transition metals are acidic. Chromium and rhenium, for example, both form oxides which are acidic in water.
Are metal's oxides gases or bases?
Metal oxides are typically basic.
Are metal oxides neutral?
Many metal oxides are alkaline and form hydroxides in the presence of water.
Are all oxides acidic?
No. A number of metal oxides are basic.
Are metals oxides acidic?
No, metal oxides are basic in nature.
How does the acid-base nature of the oxides in the period 3 change with the increasing atomic number?
basic metal oxides change to acidic non-metal oxides
What do metal oxides form?
Metal Salts + water
Is carbon often used to reduce metal oxides to the metal?
Yes, carbon has been used since ancient times to reduce metal ores and oxides to the metal.
What are the classifications of inorganic pigments?
Inorganic pigments are classified as single-metal oxides, mixed-metal oxides, and earth colors.
Why does metal combustion leaves ashes?
The product of combustion of metals are metal oxides. The final product of combustion of most organic materials, such as wood, also consists largely of metal oxides, such as potassium-, sodium- and magnesium oxides.
Which type of oxide is formed when metals combine with oxygen?
Metal oxides form alkalis when they dissolve in water. Non-metal oxides for acids. For example: carbon dioxide + water --> carbonic acid magnesium oxide + water --> magnesium hydroxide
