If a sugar compound has 11 oxygen atoms, how many hydrogen atoms does it contain?

The answer is:  22 hydrogen atoms.

Carbohydrates, including sugar, have a ratio of:

CₙH₍₂ₙ₎Oₙ  ;   so the number of hydrogen atoms will always be double the number of oxygen atoms;  the number of oxygen atoms will be always equal; the number of carbon atoms; the number of hydrogen atoms will always be be double the number of hydrogen atoms.  

So, we are given:  "a sugar compound has 11 oxygen atoms"; we know the compound will have twice that amount of hydrogen atoms; or, 11 * 2 (hydrogen atoms); or, 22 hydrogen atoms.

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.
