In my opinion, the correct answer among the choices presented above is option C. <span>A material is nonmagnetic and gaseous and does not conduct heat or electricity. It will, however, react with other elements. It is most likely a nonmetal.</span>
Answer:
a
n=m/M
mass if 85 gms and molar mass is 169.87 g/mol
85/169.87=0.50038 moles
Explanation:
<em> Infrared Waves</em> is the answer
Let me know if this helps..
CO₂ does not have dipole-dipole forces as its strongest force.
Draw the 3D structures of each molecule. All have C-O, C-Br, or C-Cl <em>bond dipoles</em>.
In CO₂ the C-O bond dipoles point in opposite directions, so they cancel.
CO₂ has <em>no molecular dipole</em>. Its strongest intermolecular forces are <em>London dispersion forces</em>.
In all the other molecules, the C-Br, C-Cl, and C-O bond dipoles do not cancel. These molecules all have intermolecular dipole-dipole forces.
