A25.0-ml sample containing cu2+ gave an instrument signal of 25.2 units (corrected for a blank). when exactly 0.500 ml of 0.0275 m cu(no3)2 was added to the solution, the signal increased to 45.1 units. calculate the molar concentration of cu2+ assuming that the signal was directly proportional to the analyte concentration. skoog, douglas a.. principles of instrumental analysis (p. 20). brooks cole. kindle edition.

The human eye contains a molecule called 11-cis-retinal that changes shape when struck with light of sufficient energy. the change in shape triggers a series of events that results in an electrical signal being sent to the brain that results in vision. the minimum energy required to change the conformation of 11-cis-retinal within the eye is about 164 kj/mol.
