With the haber process, how many grams of hydrogen will be needed to make 0.3820 pounds of ammonia? needed to 3 decimal places for pounds to grams conversion.

i’m having a mental block on part of this and would greatly appreciate ! !

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.

Reactions in cells take place at about a. 40°c b. 0° c. 100°c d. 60°c
