A technique called spectrophotometry uses light intensity measurements as a beam of light travels through a sample solution to determine how much a chemical compound absorbs light.
Every chemical either absorbs or transmits light across a specific spectrum of wavelengths, according to the fundamental principle.

There are two main techniques used among the various forms of spectrophotometry:
ultraviolet-visible range spectrophotometry, which examines the reflectance of certain spectra,
and absorption spectrophotometry, which examines the absorption of radiation and particular spectra of light.

Applications of spectrophotometry are useful for determining how well gases, liquids, and solids transmit, reflect, and absorb light.

Answer:

n= -13

Explanation:

-22 = -9 + n

first flip the equation

n + -9 = -22

then add 9 beacuse we need to do the opposite to find n

so -22 + -9 = - 13

so n = -13

plz mark brainliest i just need 1 more plz plz plz!
