Molar absorptivities (ε, M-1cm-1) of compounds X and Y were measured in pure samples at two different λ and are given below:

λ, nm X Y

250 14,350 2,505

310 2, 708 6,502

A mixture if these two compounds was tested in a 1.0 cm cell. And following

absorbances (A) were obtained:

λ, nm A

250 0.910

310 0.575

Find concentrations of X and Y in the mixture.

this is the answer

Explanation:

b. acid is the correct answer @jayxboof all social media

acid : acids are those which accepts an electron-pairs.

base : bases are those which donates ab electron-pairs.

alkali : it is a base that dissolves in water. it is basically a base and the ph greater than 7.

hydroxide ion : it is a poly-atomic ion which is negatively charged.

that tool would be a compass
