The approximate degree of dissociation of a 0.35 M solution of lactic acid is 4,87%
<h3>What is degree of dissociation?</h3>The degree of dissociation is the quantity used to express the strength of a base, that is, its ability to conduct electric current, which depends on the amount of ions released in the dissociation.
The degree of dissociation (α) is another way of determining the strength of a base. It indicates the fatty acids that were released from a base when it dissociates in water.
With that being said, C stands for concentration and α is the the degree of dissociation.
Latic Acid can be written as C3H6O3
As α is too small (1-α) can be neglected.
In this case, is possible to see that approximate degree of dissociation of a 0.35 M solution of lactic acid is 4,87%

Answer:
Explanation:
The correct format for the Table is shown below:
Generic Reactions Reactants Products Transition state
Synthesis
A + B → AB A+B = -15 kJ AB = 20 kJ 30 kJ
Single
Replacement
C + AB → CB + A C + AB = 65 kJ CB + A = 30 kJ 85 kJ
Double
Replacement
AB+CD → AD+CB AB+CD = 10 kJ AD+CB = 60 kJ 70 kJ
We are to create our own potential energy diagrams for each of the three chemical reactions.Then you will analyze the data and your diagrams for each reaction.
THE POTENTIAL ENERGY DIAGRAMS FOR THE THREE CHEMICAL REACTIONS & THE ANALYSIS ARE SHOWN IN THE DIAGRAMS ATTACHED BELOW .
the total change in enthalpy and the activation energy using the energy values provided for each reaction is :
Activation Energy Enthalpy change
Synthesis reaction 45 kJ + 35 kJ
Single replacement 20 kJ - 35 kJ
reaction
Double replacement 65 kJ + 50 kJ
A molecular structure is a shape of a molecule, a three-dimensional shape or configuration of a molecule that is dependent on the preferred spatial orientation of covalent bonds to atoms having two or more partners. Attached is the diagram for the molecular structure of So42
