according to the arrhenius definition of acids and bases, acids produce [ select ] and bases produce [ select ] when in aqueous solutions.

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)

What is impossible to do with a hypothesis

Match the mixture with the substance// i really need on this guys (it’s a pic btw)
