1.Explain the difference between a FIXED VOLUME and an ELASTIC VOLUME
In-s [12.5K]

Answer:

Fixed volume is the property of liquid and solid which means that the volume of both solid and liquid remain fixed or constant under fixed temperature and pressure.

Elastic Volumes makes it easy to dynamically increase capacity, tune performance, and change the type of any new or existing current generation volume with no downtime or performance impact.

In the laboratory, a general chemistry student measured the pH of a 0.329 M aqueous solution of benzoic acid, C6H5COOH to be 2.3
Nesterboy [21]

Answer:

The dissociation constant for the acid ( experimental ) is 1.45 lit/mol

Explanation:

The value of dissociation constant can be calculated as,

  K_{a} = C × ∝²

Where, C = concentration of the solution = 0.329M

          ∝ = Degree of dissociation

again , Degree of dissociation can be obtained form :

                      p_{H} = C × ∝

                         ∝ = \frac{p_{H} }{C}

                        ∝ = \frac{2.327}{0.329} = 7.072

So, now K_{a} = C × ∝²

                     = 0.329 ×( 7.072)²

                     = 1.45 lit/ mol
