Answer: The stronger conjugate base is, Citric acid.
Explanation :
The value of dissociation constant of Benzoic acid is higher than the citric acid. This means that the acid will readily dissociate and stronger will be the acid. Higher the value of dissociation constant of an acid weaker will be its conjugate base and the lower value of dissociation constant of an acid means that the stronger will be its conjugate base.
Therefore, the stronger conjugate base is Citric acid.
The answer is Ga.
That is gallium (Ga), correctly names the element that Mendeleev predicted would be discovered and placed in the aluminum column.
Gallium (Ga) is the element that Mendeleev predicted would be discovered and placed in the aluminum column.
So the answer is Gallium (Ga) that is there in the 13th group of periodic table or in aluminium column.
Answer:
<em><u>A. any absorbance of light by the solvent AND the cuvette needs to be accounted for</u></em>
Explanation:
Blank calibrations are usually carried out on the spectrometer to eliminate and account for any readings that would come from absorptions of the curvette, solvents/reagents or anything that is not the main analyte we are testing for.
Hence the blank solution does not contain the analyte itself. Fingerprints should be removed from the curvette as practice. Hence the most suitable answer amongst the options is A.
I hope this was clear ad most of all, helpful.
