For the following reaction: 5Ca + V2O5 --> 5CaO + 2V

In one process 5 mol of V2O5 react with 3 mol of Ca.

Calculate the theoretical yield of V in the unit of mol.

For your answer, type in only the number that carries one digit after the decimal point (e. g. 0.5, 1.4, 12.6, etc.) Do not type in the unit which is mol.

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)
