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.
Vs = 1.0 mL = 0.001 L
c((NH4)2CO3) = <span>0.02 M
n(</span>(NH4)2CO3) = ?
For the purpose, here we will use the next equation:
c=n/V ⇒ n=cxV
n((NH4)2CO3) = 0.02M x 0.001L
n((NH4)2CO3) = 2x10⁻⁵ mole of (NH4)2CO3 is presented in the solution
C. one of the discoveries he made which gave him his fame in the scientific community was that the atom could not be destroyed
Answer:
4.46
Explanation:
Applying,
pH = -log(H⁺)....................... Equation 1
Where H⁺ = Hydrogen ion concentration of HCl solution
From the question,
Given: H⁺ = 3.5×10⁻⁵ M
Substitute these values into equation 1
pH = -log(3.5×10⁻⁵)
pH = 4.46
Hence the pH of HCl solution is 4.46
well for a start you need to learn how to type correctly then you have to plan out your schedule to what you can handle. :)
