It is inorganic (does not contain carbon).
Silica IS a compound - silicon dioxide. Perhaps you mean silicates? silicones? other silicon compounds?
Yes, which is why it reacts so little with the human body.
No. Silicon is the element. Silica is the compound silicon dioxide.
No, Al2O3 is aluminum oxide, it occurs naturally as the mineral corundum. Silica is silicon dioxide or SiO2, it occurs naturally as the mineral quartz.
Silica is silicon dioxide, the most common component found in rocks and minerals. The composition of different types of magmas are assessed partly based on silica content, or the amount of silica in them. This content significantly affects how the lava behaves.
No. Silicon dioxide, also called silica or, in mineral form quartz, contains only silicon and oxygen. By definition, and organic compound contains carbon.

it is made of silica and is inorganic
Silica (silicon dioxide, SiO2)
No. It is neither organic nor a molecule. Silicon dioxide consists only of silicon and oxygen. By definition, an organic compound must contain carbon. Second, silicon dioxide forms a covalent network rather than molecules.
It is a mineral, but it is silica dioxide- SiO2
Yes, which is why it reacts so little with the human body.
No. Silica, or silicon dioxide, is acquired from common sand. In nature it occurs as the mineral quartz.
No. Silicon is the element. Silica is the compound silicon dioxide.
Hydrated silica is an inorganic material.
You might mean either silica or quartz. Please see the link.
They do not normally. Their chemical formula is SiO2 (silicon dioxide). However, the different colours of quartz follow when there are impurities in the mineral, and so carbon could be an impurity which can cause a certain colour of quartz.
