Why is silica classified as an acidic oxide?
Because it reacts with bases to form silicates.
Is there a difference between silica and silicon?
Yes. Silica is a compound with the formula SiO2, while silicon is an element with symbol Si. There are many chemical and physical differences between them.
What is differences between Zeolites and silica-alumina?
Though both of these substances are made of an aluminosilicate framework, there are some key differences in regard to their morphologies, physical properties, and acidity. For instance silica-alumina is an amorphous material, and zeolites on the other hand are cyrstalline in nature. A key physical difference is that zeolites are typically microporous (i.e. very small pores) and silica-alumina are mesoporous (i.e. moderate sized pores). Lastly the Bronsted acid sites on zeolites have been found to significanly stronger than those on silica-alumina, due to the homogeneity of the zeolite.
What the harmful effects silicon?
Silicon is not known to be toxic, but if breathed in as a fine silica/silicate dust it may cause chronic respiratory problems, even it can cause lung cancer if directly breathed in. Silicates such as asbestos are carcinogenic.
What is the difference between silica and silicon dioxide?
They are the same substance.
What are minerals containing silica called?
These are known as silicate minerals or silicates.
Does mica schist contain silica?
Yes. Mica minerals are silicates.
Is silica an organic compound?
Silica IS a compound - silicon dioxide. Perhaps you mean silicates? silicones? other silicon compounds?
Why is silica classified as an acidic oxide?
Because it reacts with bases to form silicates.
What is silicate minerals?
The minerals that contain silica. This would include quartz, as well as the silicates. The siliceous ooze is the biogenic sediment, containing the remains of organisms whose skeleton is based on silicates.
Is there a difference between silica and silicon?
Yes. Silica is a compound with the formula SiO2, while silicon is an element with symbol Si. There are many chemical and physical differences between them.
What do we call compounds of the elements silica and oxygen that include more than 90 percent of the minerals in the Earth's crust?
Silicates.
Is silica and forms of granite found in upper mantle?
Silica is found in the upper mantle, but not granite. Most of the minerals in the mantle are silicates, meaning they contain silica. Granite is found in the crust, primarily conditnental crust, as it forms from high-silica magma. The upper mantle is composed mostly of a lower-silica rock called peridotite.
What are minerals that contain oxygen and silicon?
They are classified as silicates, one of the more common being the mineral quartz which is composed only of the elements silicon and oxygen (SiO2). Other silicate minerals may include one or more other elements as well in their chemical formula.
What are the silicates made of?
Silicate minerals are those composed of silicon and oxygen atoms. Some of these minerals are quartz, feldspar, mica and olivine.
What is the difference between silica and silicates?
Silicate is made up of silicon, oxygen, and other elements (metals) such as aluminium, etc. Silicon is made up of different compounds. Basically, the difference is that silicon is one of the elements that makes up silicates but silicates is made up of silicon and many other elements.

What are the differences between sand and mineral sand?
Regular beach sand is silica - mineral sand is like fine grained quartz.
