Before measuring the absorbance of a solution with the ocean optics spectrophotometer, it is important to run a blank sample of to correct for any light absorption not originating from the solute.

a. an empty cuvette
b. the solvent being used in the experiment
c. a standard solution
d. deionized water

Many free radicals combine to form molecules that do not contain any unpaired electrons. the driving force for the radical–radical combination reaction is the formation of a new electron‑pair bond. consider the chemical equation. n(g)+no(g)⟶nno(g) n(g)+no(g)⟶nno(g) write lewis formulas for the reactant and product species in the chemical equation. include nonbonding electrons. n(g)n(g) select draw rings more erase select draw rings more erase select draw rings more erase n no(g)
