Question

Al203=>Al(No3)3=>Al(oh)3=>Al2O3 ZnCo3=>CO2=>k2co3=>H2Co3

Answer 1

Ответ:

1) Al203=>Al(No3)3=>Al(oh)3=>Al2O3

1. Al2O3 + 6HNO3 = 3H2O + 2Al(NO3)3

2. Al(NO3)3 + 3NaOH = Al(OH)3 + 3NaNO3

2. 2Al(OH)3 = Al2O3 + 3H2O

2) ZnCo3=>CO2=>k2co3=>H2Co3

1. ZnCO3 + H2SO4 = H2O + CO2 + ZnSO4

2. CO2 + K2O = K2CO3

3. K2CO3 + H2O = K2O + H2CO3

Answer 2

It seems like you've written a series of chemical reactions involving different compounds. Let me break down these reactions for you:

1. Aluminum Oxide (Al₂O₃) => Aluminum Nitrate (Al(NO₃)₃)

   • Aluminum oxide reacts with nitric acid (HNO₃) to form aluminum nitrate:
   • Al₂O₃ + 6HNO₃ → 2Al(NO₃)₃ + 3H₂O

2. Aluminum Nitrate (Al(NO₃)₃) => Aluminum Hydroxide (Al(OH)₃)

   • Aluminum nitrate reacts with sodium hydroxide (NaOH) to form aluminum hydroxide:
   • 2Al(NO₃)₃ + 6NaOH → 2Al(OH)₃ + 6NaNO₃

3. Aluminum Hydroxide (Al(OH)₃) => Aluminum Oxide (Al₂O₃)

   • Aluminum hydroxide can be dehydrated to form aluminum oxide:
   • 2Al(OH)₃ → Al₂O₃ + 3H₂O

4. Zinc Carbonate (ZnCO₃) => Carbon Dioxide (CO₂)

   • When heated, zinc carbonate decomposes to produce carbon dioxide gas and zinc oxide:
   • ZnCO₃ → ZnO + CO₂

5. Carbon Dioxide (CO₂) => Potassium Carbonate (K₂CO₃)

   • Carbon dioxide can be absorbed by a solution of potassium hydroxide (KOH) to form potassium carbonate:
   • CO₂ + 2KOH → K₂CO₃ + H₂O

6. Potassium Carbonate (K₂CO₃) => Carbonic Acid (H₂CO₃)

   • Potassium carbonate can react with carbon dioxide in the air to form carbonic acid:
   • K₂CO₃ + CO₂ + H₂O → 2H₂CO₃

These reactions describe the transformations of the mentioned compounds in a series of chemical reactions. If you have any specific questions about these reactions or if you'd like more information about any of them, please feel free to ask.
