Answer 1

Решение:

          1)          2)               3)              4)            5)                6)

CaCO₃ → CaO → Ca(OH)₂ → Fe(OH)₃ → Fe₂O₃ → Fe(NO₃)₃ → Al(NO₃)₃

1) CaCO₃ (t°C) → CaO + CO₂

2) CaO + H₂O → Ca(OH)₂

3) 3Сa(OH)₂ + 2FeCl₃ → 2Fe(OH)₃↓ + 3CaCl₂

4) 2Fe(OH)₃ (t°C) → Fe₂O₃ + 3H₂O

5) Fe₂O₃ + 6HNO₃ → 2Fe(NO₃)₃ + 3H₂O

6)  Fe(NO₃)₃ + AlPO₄ = Al(NO₃)₃ + FePO₄↓

Answer 2

Chemical Reactions:

The chemical reactions you provided are as follows:

1. Caco3 -> cao + ca(oh)2 2. Fe(oh)3 -> fe2o3 3. Fe(no3)3 4. Al(no3)3

Let's break down each reaction and provide more information:

1. Caco3 -> cao + ca(oh)2: - This reaction represents the decomposition of calcium carbonate (CaCO3) into calcium oxide (CaO) and calcium hydroxide (Ca(OH)2).

2. Fe(oh)3 -> fe2o3: - This reaction represents the dehydration of iron(III) hydroxide (Fe(OH)3) to form iron(III) oxide (Fe2O3).

3. Fe(no3)3: - Iron(III) nitrate (Fe(NO3)3) is a compound that consists of iron (Fe) and nitrate ions (NO3-).

4. Al(no3)3: - Aluminum nitrate (Al(NO3)3) is a compound that consists of aluminum (Al) and nitrate ions (NO3-).
