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.
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
What do metal hydroxides decompose yield?
metal oxides and water
Which metal oxides are insoluble in water and which are soluble?
Metal oxides of high reactivity are soluble in water while those of moderate reactivity are insoluble in water.
Many metal hydroxides decompose when heated to yield metal oxides and?
H2O i think
What are neutral oxides?
Neutral Oxides are non-metal oxides which do not react with acids or bases. All neutral oxides are monoxides (e.g. Carbon monoxide) Neutral Oxides are those oxides which on contact with water produce neither nor base. Their aqueous solution have no action on blue or red litmus .Examples are nitric oxide (NO) and nitrous oxide (N2O)
Is NaI acidic neutral or basic?
sodium oxide, Na2O, is basic. This is because it is a metal oxide. Metal oxides tend to be basic while non metal oxides tend to be acidic.
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
Which non-metal will ignite spontaneously if it is exposed to oxygen?
When a non metal reacts with oxygen it produces acidic or neutral oxides
What are neutral oxides of carbon?
The oxides of carbon are CO and CO2.
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 all oxides acidic?
No. A number of metal oxides are basic.
Are metals oxides acidic?
No, metal oxides are basic in nature.
Are non metal oxides acids or bases?
Metallic oxides are basic because they dissociate to form the hydroxyl ions while the non-metallic oxides are acidic because they dissociate to form hydrogen ions.
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
