Can the cation affect the color of a solution? Can the anion affect the color of a solution? Provide supporting evidence for each case. Several different batches of drink mix have different appearances. The solution is supposed to be somewhat red in color, but that is not always the case. What do you think went wrong? Provide a plausible reason, consistent with the observations.

Asample of silver (with work function ? = 4.52 ev) is exposed to an ultraviolet light source (? = 200 nm), which results in the ejection of photoelectrons. what changes will be observed if: silver is replaced with copper (? = 5.10 ev) more photoelectrons ejected no photoelectrons are emitted fewer photoelectrons ejected more energetic photoelectrons (on average) less energetic photoelectrons (on average)

The p sub shell can hold up to 8 electrons in an atom. true or false?
