Answer: Option (A) is the correct answer.
Explanation:
A phenomenon where delocalization of pi electrons or non-bonding electrons takes place is known as resonance.
For example, in a 
molecule two oxygen atoms contain -1 charge. And, delocalization of pi electrons takes place in order to attain stability.
When in a molecule, there occurs unequal sharing of bonding electrons by a chain of atoms then there occurs a permanent dipole moment. And, this effect is known as inductive effect.
So, basically more difference in electronegativity of the atoms in a molecule tend to cause inductive effect.
In , there is not much difference in the electronegativity of carbon and oxygen atom.
Hence, resonance effect predominates inductive effect.
Potential energy is the energy obtained by an object due to its position.
Thus, we can conclude that the ion is stabilized by resonance.
Manganese since the atomic number is 25
Answer:
yes, A double replacement reaction has two compounds as reactants.
hence it's true.......
The volume of sample = 2.25(1.5)(2.25) = 7.59375 cm3
Density = mass / volume
Density = 55.75 / 7.59375 = 7.34156 g/cm3
As the density of iron is 7.86 g/cm3 instead, it is not iron
Answer:
reee, here is your answer.
Explanation: CH3OH(l) + 3O2(g) rightarrow CO2(g) + 3H2O(g) CH3OH(l) + O2(g) rightarrow CO2(g) + 2H20(g) CH3OH(l) + 2O2(g) rightarrow 2CO2(g) + 4H20(g) 2CH3OH(l) + 3O2(g) rightarrow 2CO2(g) + 4H20(g) Correct Calculate Delta H degree rxn at 25 degree C.
