CH3COONa + NaOH overset(CaO) to CH4+Na2CO3

Admin

The correct Answer is:C


To complete the reaction of sodium acetate (CH₃COONa) with sodium hydroxide (NaOH) in the presence of calcium oxide (CaO), we will follow these steps:

1. Identify the Reactants:
The reactants in this reaction are sodium acetate (CH₃COONa) and sodium hydroxide (NaOH), along with calcium oxide (CaO) which acts as a dehydrating agent.

2. Understand the Reaction Type:
This reaction is a decarboxylation reaction, which occurs when a carboxylic acid salt is heated with a strong base and a dehydrating agent. In this case, we are using soda-lime (a mixture of NaOH and CaO).

3. Write the Reaction:
The sodium salt of acetic acid (sodium acetate) reacts with sodium hydroxide and calcium oxide. The decarboxylation process will lead to lớn the formation of methane (CH₄) and sodium carbonate (Na₂CO₃).

The balanced reaction can be written as:
CH3COONa+NaOH+CaOCH4+Na2CO3

4. Identify the Products:
The products of this reaction are methane (CH₄) and sodium carbonate (Na₂CO₃).

5. Final Equation:
Thus, the complete reaction is:
CH3COONa+NaOH+CaOCH4+Na2CO3
