Answer:
Metals and non-metals are substances that can be differentiated on the basis of various physical and chemical properties. Metals are the elements that are generally hard as strong metallic bond exists between the atoms. As against non-metals are the elements which are usually soft.
Just observing an physical property of a substance cant not change the substances identity. You can only figure out its identity through test and the figuring out of the elements! I hope I was of some help!!
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.
