Hello there!
In this case, since this problem can be understood via the Graham's law, which states that states that the rate of diffusion or of effusion of a gas is inversely proportional to the square root of its molecular weight, which can be extrapolated to the rate, we have:
Thus, since the molar mass of helium is 4.0 g/mol and that of oxygen is 16.0 g/mol, we solve for the average velocity of helium as shown below:

Answer:
polar covalent bonds
Explanation:
Phosphorus trichloride is a chemical compound of phosphorus and chlorine, having the chemical formula PCl 3. It has a trigonal pyramidal shape, owing to the lone pairs of electrons on the phosphorus atom.
Chlorine is more elctronegative than phosphorus . Phosphorus has a lone pair of electrons and every chlorine atom has three pairs of electrons . The molecule is not symmetrical as the shared electron pairs are closer to the chlorine atoms than the phosphorus atoms , the chlorine atoms are shifted towards one side of the center of the molecule , thus a net dipole effect is created. This is the reason why the molecule is polar .
Answer:
The mechanism for the formation of hexamethylenetetraamine predicts the formation of aminomethanol from the addition of ammonia to formaldehyde. This molecule subsequently undergoes unimolecular decomposition to form methanimine and water.
