How do hollow bones improve the survival of birds? (1 point )

Chemistry
1 answer:
OLEGan [10]2 years ago
7 0

Answer:

Hollow bones allow the birds to fly. They're quite dense, and that density allows for flight! Because we humans do not have hollow bones, our bodies are much too heavy to fly on our own. If we did, we'd probably be able to fly.

Fifteen points! Nothing like chemistry quizzes in the morning... &gt;o&lt;
sertanlavr [38]

Answer:

Explanation:

HA(aq)+H2O(l)⟺H3O+(aq)+A−(aq)(1)

you need to solve for the Ka value. To do that you use

Ka=[H3O+][A−][HA](2)

Another necessary value is the pKa value, and that is obtained through pKa=−logKa

The procedure is very similar for weak bases. The general equation of a weak base is

BOH⟺B++OH−(3)

Solving for the Kbvalue is the same as the Ka value. You use the formula  

Kb=[B+][OH−][BOH](4)

The pKb value is found through pKb=−logKb  

The Kw value is found withKw=[H3O+][OH−].  

Kw=1.0×10−14(5)
