Question

Выполните цепь химических уровнений:Si- Na2SiO3- H2SiO3-CO2

Answer 1

Si + O2 + Na2O=Na2SiO3
Все под температурой т.к. Без неё не получится оксид кремния.

Na2SiO3 + 2HNO3 = H2SIO3 (осадок) + 2NaNO3

H2SIO3 + Na2CO3 = H2O + CO2(газ) + Na2SiO3

Answer 2

Chemical Equations:

The given chemical equation chain is as follows:

1. Si 2. Na2SiO3 3. H2SiO3 4. CO2

Please note that the search results provided do not directly provide a complete chemical equation chain for the given compounds. However, we can use our knowledge of chemical reactions to deduce the possible reactions involving these compounds.

Based on the given compounds, we can propose the following chemical reactions:

1. Reaction 1: - Si + 2NaOH + H2O → Na2SiO3 + 2H2 - This reaction involves the reaction of silicon (Si) with sodium hydroxide (NaOH) and water (H2O) to form sodium silicate (Na2SiO3) and hydrogen gas (H2).

2. Reaction 2: - Na2SiO3 + CO2
