grandymaker [24]
The human eye contains a molecule called 11-cis-retinal that changes conformation when struck with light of sufficient energy. The change in conformation triggers a series of events that results in an electrical signal being sent to the brain. The minimum energy required to change the conformation of 11-cis-retinal within the eye is about 164 {\rm kJ}/{\rm mol}.

Give the chemical formula and systematic name for aurous sulfide, which is named using the older nomenclature. spelling counts!
Bingel [31]
Aurous is a cation of gold. Gold takes the name "aurum" (Au) with atomic number of 79. In its purest form, the element is bright, slightly yellow, soft, ductile, and malleable. The charge of aurous is +1. Sulfide, on the other hand, has a charge of -2. 

Hence, the chemical formula of the compound is Au₂S and its systematic name is gold (I) sulfide.
