Question

SiO2 - H2SiO3.Почему в кислоте стало 2 водорода и 3 оксида?

Answer 1

Оксид - SiO2 соответствует кислоте - H2SiO3 - кислота двухосновная.

Answer 2

Explanation of SiO2 to H2SiO3 Transformation

The transformation from SiO2 to H2SiO3 involves the addition of water molecules to silicon dioxide. This process results in the formation of silicic acid, which contains two hydrogen atoms and three oxygen atoms.

The balanced chemical equation for this transformation is:

SiO2 + 2H2O → H2SiO3

The addition of two water molecules to silicon dioxide leads to the formation of silicic acid, H2SiO3, with the release of two hydrogen atoms and three oxygen atoms.

This transformation can be represented as follows: - SiO2 + H2O → H2SiO3 - H2SiO3 can also be written as H2O3Si for clarity.

The addition of water to silicon dioxide results in the formation of silicic acid, which is a weak acid.

The transformation from SiO2 to H2SiO3 involves the hydration of silicon dioxide, leading to the formation of silicic acid with the release of two hydrogen atoms and three oxygen atoms.

Conclusion

The transformation of SiO2 to H2SiO3 involves the addition of water molecules to silicon dioxide, resulting in the formation of silicic acid with two hydrogen atoms and three oxygen atoms. This process is represented by the balanced chemical equation: SiO2 + 2H2O → H2SiO3.
