A solid sample of Zn(OH)2 is added to 0.400 L of 0.550 M solution of HBr. The solution that remains is still acidic. It is then titrated with 0.500 M NaOH solution, requiring 165 mL of the NaOH solution to react completely. What mass of Zn(OH)2 was added to the HBr solution

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.
