Write the equilibrium expression for the following reaction. Based upon the value of K, would you expect there to be more or less product in the equilibrium mixture? Why? CaO (s) + CH4 (g) + 2H2O (g) -> CaCO3 (s) + 4H2 (g) Kp=2344

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)
