Answer:
7.92 .g . mL^-1
Explanation:
Data provided in the question
Water liters = 45.5 mL
Pace of iron = 28.5 gram
Rise in the water in the cylinder = 49.1 mark
So by considering the above information
As we know that
where,
Mass = 28.5 gram
Volume = 49.1 - 45.5
= 3.6 mL
So, the density is
= 7.92 .g . mL^-1
Basically we use the density formula by dividing the mass with the volume
The number of electrons, which are present in the nonbonding π molecular orbital of the allyl anion is "0".
Anions, cations, but also allylic radicals have always been frequently mentioned as reaction intermediates. Each one has three adjacent -hybridized carbon centers, and they all rely on resonance for stability. Two resonance structures would be used to present each species, with the charge as well as unpaired electron scattered across both the 1,3 and 0 positions.
The Aufbau principle states that these orbitals would fill up based on the order of stability, therefore a typical pi bond, will have 2 electrons in the Pi orbital as well as zero in the Pi* orbital.
Therefore, the correct answer will be option (d)

The fraction of acetic acid that is dissociated is 0.18
Why?
The chemical equation for the dissociation of acetic acid (HAc) is the following:
HAc(aq) + H₂O(l) ⇄ H₃O⁺(aq) + Ac⁻(aq)
To find the fraction of acetic acid that is in the dissociated form (f), we apply the following equation (Ka for acetic acid is 1.76*10⁻⁵). This equation comes from solving the equation of the equilibrium constant for the dissociated fraction of HAc:
