Q. Calculate the value for the rms speed of thermal agitation of the 7-38 molecules of helium in a vessel at 30° C. Density of helium at STP -0.01785 kgm-³​

This is what i found on google “what happens to the bond angle when you add or remove an electron domain? the bond angle decreases as you add domains 5. can you force the atoms into new configurations by pushing atoms around? note: we can think of a bond or a lone pair of electrons as a “domain” of electrons.” i hope this you
