Question

SO3+H2O-> Na2O+H2O-> HgO->t° C2H6+O2-> KMnO4->t° SiO2+H2O->

Answer 1

Ответ:

SO3 + H2O = H2SO4

Na2O + H2O = 2NaOH

2HgO = 2Hg + O2 (t)

2C2H6 + 7O2 = 4CO2 + 6H2O

2KMnO4 = K2MnO4 + MnO2 + O2

SiO2 + H2O =/

Объяснение:

1. кислотный оксид + вода = кислота

2. растворимый основный оксид + вода = растворимое основание

3. основный оксид = металл + кислород (t)

4. окислительно-восстановительная реакция

5. окислительно-восстановительная реакция

6. реакция не пойдет, т. к. SiO2 - нерастворимый оксид

Answer 2

It seems like you've listed a series of chemical reactions, but the notation is a bit unclear. I'll try to interpret what you're asking for:

1. SO3 + H2O: This reaction can form H2SO4 (sulfuric acid).

2. Na2O + H2O: This reaction can form NaOH (sodium hydroxide), which is a strong base.

3. HgO: This compound is mercury(II) oxide.

4. C2H6 + O2: This is the combustion of ethane (C2H6) in the presence of oxygen to form carbon dioxide (CO2) and water (H2O).

5. KMnO4: This compound is potassium permanganate, a powerful oxidizing agent.

6. SiO2 + H2O: This reaction can form silicic acid (H4SiO4) when silicon dioxide reacts with water.

If you have specific questions about any of these reactions or need more information about them, please let me know, and I'll be happy to provide further details.
