What is the oxidation number of oxygen in SiO2?

The oxidation number of oxygen in SiO2 is -2. In this compound, silicon is assigned an oxidation number of +4 since it is a representative element in group 14, so the total oxidation numbers must add up to zero for a neutral compound.


What is the oxidation number in SIO2?

The oxidation number of Si in SiO2 is +4 because oxygen typically has an oxidation number of -2 and there are 2 oxygen atoms bonded to the silicon atom. The sum of the oxidation numbers in a neutral compound like SiO2 must equal zero.


Why SiO2 in Mosfet?

Yes, SiO2 is used for isolation and it can be grown easily when compared to other materials. The process is also simple as it only required oxidation of the already existing Si layer


What is the oxidation number of HClO?

Hydrogen's oxidation number is +1.Chlorin's oxidation number is +1.Oxygen's oxidation number is -2.


What is the oxidation number of acetate?

The oxidation number of acetate (CH3COO-) is -1. The carbon atom has an oxidation number of +3, each hydrogen atom has an oxidation number of +1, and the oxygen atoms have an oxidation number of -2.


What is the oxidation number of H2CO2?

The oxidation number of each hydrogen in H2CO2 is +1, while the oxidation number of each carbon in CO2 is +4. This is because hydrogen usually has an oxidation number of +1, and oxygen usually has an oxidation number of -2.


What is the Oxidation number of sand?

Silicon's oxidation number is +4.Oxygen's oxidation number is -2


What is the oxidation number of nitrosyl?

The oxidation number of nitrosyl (NO) is +1. Nitrogen typically has an oxidation number of -3, and oxygen typically has an oxidation number of -2. In NO, nitrogen has a -3 oxidation number and oxygen has a -2 oxidation number, leading to an overall oxidation number of +1 for the nitrosyl ion.
