Pb(SO4)2 + LINO3 = pb(NO3)4 + Li2SO4 how many moles of lithium nitrate will be needed to make 30 moles of lithium sulfate

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.
