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:
C
Explanation:
Pb + H2O + O2 => Pb(OH)2
Number of oxygen atom on left = 3
Number of oxygen atom on the right = 2
To balance number of oxygen
Change the coefficient of Pb and H2O to two each
2Pb + 2H2O + O2 => 2Pb(OH)2
The coefficient of Pb and H2O is 2,2

Answer:
hydrogen atom when it drops from N 5 to N 2?
so, 275 kJ of energy is released when one mole of electrons "falls" from n = 5 to n = 2. E = hc/λ (this energy corresponds to the energy of one photon; the energy calculated in this problem is for one mole of photons so we will change this after we change the units from kJ to J)
