What diagram shows the ionic compound of magnesium oxide

What is the mass defect of a mole of nuclei with 1.8 x 10^15 j/mol binding energy?

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.
