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.
One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
