Question

SiO → Si→ Na2SiO3 → Na2SO4 → NaNO3

Answer 1

1) 2SiO (t°) > O2↑ + 2Si

2) Si + 2NaOH + H2O = 2H2↑ + Na2SiO3

3) Na2SiO3 + H2SO4 = H2SiO3↓ + Na2SO4

4) Na2SO4 + Ba(NO3)2 = BaSO4↓ + 2NaNO3

Answer 2

It looks like you've provided a sequence of chemical reactions involving different compounds. Let's break down each step of the reaction sequence:

1. SiO: This likely refers to silicon dioxide, which is commonly known as silica. It's a compound composed of silicon and oxygen.

2. Si: This represents silicon, which is an element and a component of silicon dioxide (SiO2).

3. Na2SiO3: This is sodium silicate, a compound formed by reacting silicon dioxide with sodium hydroxide (NaOH). It's often used in various industrial applications, including as a binder in detergents and as a source of silicon for some chemical processes.

4. Na2SO4: This stands for sodium sulfate, a compound made up of sodium, sulfur, and oxygen. It's commonly used in detergents, paper production, and as a laboratory reagent.

5. NaNO3: This represents sodium nitrate, a compound composed of sodium, nitrogen, and oxygen. It's often used as a fertilizer, food preservative, and in the production of various chemicals.

It seems like you've provided a sequence of transformations where silicon dioxide (SiO2) undergoes different reactions to ultimately yield sodium nitrate (NaNO3). Each step in the sequence involves different chemical reactions and compounds. If you have specific questions about any of these reactions or compounds, or if you'd like more information about a particular aspect of this sequence, please feel free to ask!
