Write the reaction equations: Si- SiO2- Na2SiO3- SiO

To carry out the above chain of transformations, we need to carry out the following reactions:

Interaction of silicon with oxygen. This reaction takes place under the influence of temperature. As a result of the reaction, silicon oxide is formed.

Si + O2 = SiO2

The interaction of silicon oxide and sodium hydroxide, as a result of the reaction, the substance sodium metasilicate and water are formed.

SiO2 + 2 NaOH = Na2SiO3 + H2O

Decomposition of sodium metaloselicate under the influence of temperature, as a result of reaction to water and silicon oxide.

H2SiO3 = H2O + SiO2.
