What is the nuclear binding energy of an atom that has a mass defect of 5.0446 x 10-29 kg?
Use E = mc2. (Remember: The speed of light is approximately 3.00 x 108 m/s.)
5.61 x 10-46 J
O 1.51 x 10-20 J
O 4.54 x 10-12
O 1.78 x 1045 J

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.

Which fact represents evidence for the big bang theory?

Aroom with dimensions 7.00m×8.00m×2.50m is to be filled with pure oxygen at 22.0∘c and 1.00 atm. the molar mass of oxygen is 32.0 g/mol. how many moles noxygen of oxygen are required to fill the room? what is the mass moxygen of this oxygen?
