the 3 should be at the bottom of the H
They are both on animals (not humans). IDK, maybe?
A) Time for salt to dissolve.
This factor depends on the other steps mentioned to dissolve the salt.
Answer is: the
molar mass of unknown molecular compound is 245.67 g/mol.
<span>m(compound) = 5.65 g.
m(benzene) = 110 g ÷ 1000 g/kg = 0.11 kg.
ΔT = 5.45°C - 4.39°C.</span>
ΔT = 1.06°C.
Kf(benzene) = 5.07°C/m.
<span>M(compound) = Kf
· m(compound) / m(benzene) · ΔT.
M(compound)= 5.07°C/m · 5.65 g / (0.11 kg · 1.06°C).
M(compound) = 245.67 </span>g/mol.
Answer:
True
Explanation:
Due to the arrangement of the molecule, a carbon dioxide molecule is non-polar.
