A. Calculate the percent ionization of 0.135 M lactic acid (Ka=1.4×10−4). Express the percent ionization to two significant digits.

B. Calculate the percent ionization of 0.135 M lactic acid in a solution containing 8.0×10−3 M sodium lactate.
Express the percent ionization to two significant digits.

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)

Will mark brainliest how many electrons can be held in the energy level n = 4?
