Copper(ii) sulfate forms a bright blue hydrate with the formula cuso 4 ⋅ n h 2 o ( s ) . if this hydrate is heated to a high enough temperature, h 2 o ( g ) can be driven off, leaving the grey‑white anhydrous salt cuso 4 ( s ) . a 14.220 g sample of the hydrate was heated to 300 ∘ c . the resulting cuso 4 ( s ) had a mass of 8.9935 g . calculate the val

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)
