Answer:
B: The behaviors an animal must display in order to find a mate
Explanation:
An animal usually looks for specific characteristic in order for their offspring to develop those same characteristics and be able to survive
Answer: fat show the first half and a lot of people in a row in this rr
It should be organized in people
From the periodic table:
molecular mass of carbon = 12 grams
molecular mass of fluorine = 18.99 grams
molecular mass of chlorine = 35.5 grams
Therefore:
one mole of CF2Cl2 = 12 + 2(18.99) + 2(35.5) = 120.98 grams
Therefore, we can use cross multiplication to find the number of moles in 79.34 grams as follows:
mass = (79.34 x 1) / 120.98 = 0.6558 moles
Now, one mole contains 6.022 x 10^23 molecules, therefore:
number of molecules in 0.65548 moles = 0.6558 x 6.022 x 10^23
= 3.949 x 10^23 molecules
<span>Answer: B. Ionic solids have higher melting points than molecular solids.

This is because the rest are false, as solids are able to melt, and do have melting points. Also, not all solids have the same melting points.
