Answer:
Methane gas is formed in this reaction. After adding aqueous acid, ethyl acetoacetate is reformed through protonation of it.
Explanation:
acts as base towards ethyl acetoacetate. Because ethyl acetoacetate contains active methylene group.
Hence
abstracts a proton from methylene group and being converted to methane gas.
After addition of aqueous acid, conjugate base of ethyl acetoacetate gets protonated and ethyl acetoacetate is reproduced.

Answer:
147.222 degrees C
Explanation:
assuming its 297 F it should be correct
Answer : The pH of the solution is, 2.67
Explanation :
The equilibrium chemical reaction is:

Initial conc. 0.450 0 0
At eqm. (0.450-x) x x
As we are given:

The expression for equilibrium constant is:

Now put all the given values in this expression, we get:


The concentration of
= x = 0.00212 M
Now we have to calculate the pH of solution.
![pH=-\log [H^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%20%5BH%5E%2B%5D)


Therefore, the pH of the solution is, 2.67
Answer:
The answer to the first question is B) left and the answer to the second question is A) right.
Explanation:
To solve these questions, we must remember that if a change is made to the system, the system will work to reduce that change. In these problems, if we add one reactant/product, the system will shift to use this compound and re-establish equilibrium.
For the first question, H2 is a product. If we add H2 to the system, the equilibrium will shift to the left to decrease the concentration of H2. The second question is the opposite since we are adding CH4 (a reactant). When CH4 is added, the system shifts to the right to decrease the concentration of CH4.
