Question

CaCo3 -> CaC2 -> C2H2 -> CH3-CH2-OH -> CH3-CH2-CL -> CH2=CH2

Answer 1

1) CaCO3 = CaO + CO2

CaO + 3C = CaC2 + CO;

2) CaC2 + 2H2O = C2H2 + Ca(OH)2;

3) C2H2 + H2 = C2H4;

4) C2H4 + H2O = C2H5OH (реакция обратимая);

5) С2Н5ОН = C2H4 + H2O (реакция дегидратации).

Chemical Reactions:

The given chemical equation shows a series of reactions starting with CaCO3 and ending with CH2=CH2. Let's break down each step:

1. CaCO3 -> CaC2: - This reaction involves the decomposition of calcium carbonate (CaCO3) to form calcium carbide (CaC2). - The balanced equation for this reaction is: CaCO3 -> CaC2 + CO2. - Calcium carbide is commonly used in the production of acetylene gas and various organic compounds.

2. CaC2 -> C2H2: - The reaction between calcium carbide (CaC2) and water (H2O) produces acetylene gas (C2H2) and calcium hydroxide (Ca(OH)2). - The balanced equation for this reaction is: CaC2 + 2H2O -> C2H2 + Ca(OH)2. - Acetylene gas is a highly flammable hydrocarbon gas that is used in welding and as a starting material for the synthesis of various organic compounds.

3. C2H2 -> CH3-CH2-OH: - The reaction between acetylene gas (C2H2) and water (H2O) under suitable conditions produces ethanol (CH3-CH2-OH). - The balanced equation for this reaction is: C2H2 + 2H2O -> CH3-CH2-OH. - Ethanol is a colorless, volatile liquid that is commonly used as a solvent, fuel, and in the production of alcoholic beverages.

4. CH3-CH2-OH -> CH3-CH2-CL: - The reaction between ethanol (CH3-CH2-OH) and hydrochloric acid (HCl) produces ethyl chloride (CH3-CH2-Cl). - The balanced equation for this reaction is: CH3-CH2-OH + HCl -> CH3-CH2-Cl + H2O. - Ethyl chloride is a colorless, flammable liquid that is used as a refrigerant, solvent, and in the production of various organic compounds.

5. CH3-CH2-CL -> CH2=CH2: - The reaction between ethyl chloride (CH3-CH2-Cl) and a strong base, such as sodium hydroxide (NaOH), results in the elimination of hydrogen chloride (HCl) and the formation of ethylene (CH2=CH2). - The balanced equation for this reaction is: CH3-CH2-Cl + NaOH -> CH2=CH2 + NaCl + H2O. - Ethylene is a colorless, flammable gas that is widely used in the production of plastics, synthetic fibers, and various organic chemicals.

Please note that the information provided above is based on the given chemical equation and general knowledge of chemistry. For more specific details and conditions of each reaction, further research or consultation with a chemistry expert may be required.
