Answer:
polar bonds are caused by different kind of atoms, because almost every atoms have different powers to attract electrons.
the answer will be the two same atoms, F2
Answer: 78.54 grams
Explanation:
According to avogadro's law, 1 mole of every substance weighs equal to its molecular mass and contains avogadro's number
of particles.
To calculate the number of moles, we use the equation:



According to stoichiometry :
2 moles of
react with 1 mole of 
0.98 moles of
react with =
moles of 
Mass of 
Thus 78.54 g of
are required to react completely with 29.5 g of NO.
<span>Assuming that there are 36 strontium and 24 phosphate, there
aren’t any equal cations and anoins because in theory only one ionic bond is
formed by a strontium with each phosphate ion. To the point that a cation will
eventually have an excess.</span>
The answer is:
It will float
