What is the product of one equivalent of phosphorus and three equivalents of hydrogen? what does its lewis structure look like?

The product is called phosphine, and it has a Lewis diagram similar to that of ammonia. The diagram shows a single pair of electron shared between each hydrogen molecule and the phosphorus molecule. One electron is from the hydrogen while the other is from phosphorus. 

Because phosphorus has 5 valence shell electrons, the remaining two electrons exist as a lone pair. Using this information, the Lewis structure of phosphine can be imagined and drawn.

The return of the wolf to yellowstone national park will probably affect the bird population to some degree, not significantly. while wolves will hunt birds when necessary, they prefer to hunt larger prey. the bird population will most likely only be affected when hunting is scarce for the wolves. birds of prey will also probably not be affected as much as other birds who spend more time on the ground hunting for food as the tend to spend more time in the air or in trees since they do not need to stay on the ground for long due to the nature of the way they hunt.
