Hydrogen reacts with oxygen to produce water. Write a balanced equation for this reaction.

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.

Suppose you wanted to make 100 grams of water. what is the molar mass of water (h2o)?
