Question

які з наведених речовин реагуватимуть між собою: хлорид заліза (3), оксид кальция, оксид міді (2),оксид вуглецю (4), водень, гідроксид натрію, соляна кислота? Підтвердіть рівняннями хімічних реакцій

Answer 1

Ответ:

Объяснение:

FeCl3 + 3NaOH = Fe(OH)3↓ + 3NaCl

CaO + CO2 = CaCO3

CaO + H2O = Ca(OH)2

CaO + 2HCl = CaCl2 + H2O

CuO + 2HCl = CuCl2 + H2O

CO2 + H2O = H2CO3

CO2 + 2NaOH = Na2CO3 + H2O

NaOH + HCl = NaCl + H2O

Answer 2

Reactions between the given substances:

The substances mentioned in the question are: - Iron chloride (FeCl3) - Calcium oxide (CaO) - Copper oxide (CuO) - Carbon dioxide (CO2) - Hydrogen (H2) - Sodium hydroxide (NaOH) - Hydrochloric acid (HCl)

Let's examine the possible reactions between these substances.

1. Iron chloride (FeCl3): - Iron chloride can react with sodium hydroxide (NaOH) to form iron(III) hydroxide (Fe(OH)3) and sodium chloride (NaCl): ``` FeCl3 + 3NaOH → Fe(OH)3 + 3NaCl ```

2. Calcium oxide (CaO): - Calcium oxide can react with water (H2O) to form calcium hydroxide (Ca(OH)2): ``` CaO + H2O → Ca(OH)2 ```

3. Copper oxide (CuO): - Copper oxide can react with hydrogen (H2) to form copper (Cu) and water (H2O): ``` CuO + H2 → Cu + H2O ```

4. Carbon dioxide (CO2): - Carbon dioxide can react with water (H2O) to form carbonic acid (H2CO3): ``` CO2 + H2O → H2CO3 ```

5. Hydrogen (H2): - Hydrogen can react with oxygen (O2) to form water (H2O): ``` 2H2 + O2 → 2H2O ```

6. Sodium hydroxide (NaOH): - Sodium hydroxide can react with hydrochloric acid (HCl) to form sodium chloride (NaCl) and water (H2O): ``` NaOH + HCl → NaCl + H2O ```

7. Hydrochloric acid (HCl): - Hydrochloric acid can react with calcium oxide (CaO) to form calcium chloride (CaCl2) and water (H2O): ``` CaO + 2HCl → CaCl2 + H2O ```

Please note that these are general reactions and may not represent the complete range of possible reactions between the given substances.
