Dependent variables are essentially what you are measuring and is kept the same, and the independent variable is what you change in the experiment
Answer:
The Highly acidic proton joined to one of the carbon in the ALKYNE bond.
(Kindly Check the attachment for the drawing because the solution will need us to draw).
Explanation:
So, let us start by defining some major key terms in this particular Question given above;
(1). ISOMERIZATION: isomerization can simply be defined as the kind is of chemical rearrangement whichay lead to the breaking and the formation of new bonds.
(2). NaNH2 BASE: Sodium amide is a Chemical compound which has a Molar mass of 39.01 g/mol and Heat capacity (C) of 66.15 J/mol K. It is also known as sodamide. It is a good nucleophile.
(3). ALKYNE BOND: it is a C-C joined together by three bonds.
The chemical reaction given in the Question is given in the attachment too.
Therefore, The Highly acidic proton joined to one of the carbon in the ALKYNE bond is removed irreversibly by NaNH2 base.
<span>A colloid can be detected by using the Tyndall effect. The correct option among all the options that are given in the question is the second option. The other choices are incorrect and can be easily neglected. I hope that this is the answer that you were looking for and the answer has actually come to your desired help.</span>
Explanation:
Using Beer-Lambert's law :
Formula used :

where,
A = absorbance of solution
c = concentration of solution
l = length of the cell
= molar absorptivity of this solution
According to question:
A = (C) : absorbance measured by the spectrometer
c = (B) : concentration, in mol/L, of the stock solution from which the sample was made
l = (A): pathlength of light through the cell
ε = (D) : molar absorptivity, a constant unique to that substance at that wavelength
