Write the electron configuration for the following elements..
Two electrons jump energy levets, electron A jumps energy level n=2 -) n=l and electron B jumps energy level
n=3 ~ n=2. Which do you predict would give off a blue color light and which would give off a yellow color light.
Explain your answer.
Definitions: oxidation, reduction, patina, oxidizing agent, reducing agent
1) Determine the oxidation number of each element in the following:
Sb~(SQ, O~
2)
Cu(NO~)~~
in the following unbalanced REDOX reaction, identify; the element oxidized (0), the element reduced
(R), the oxidizing agent (OA) and the reducing agent (RA). Write the half reactions that demonstrate
how electrons are gained and lost:
HBr + NaMn04 -> NaBr + MnBr2 + Br2 + H20
CO+I~Os -> CO~+I~
