What is the question

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

107.1 mhz has higher energy photons. the photon energy increases directly proportional to frequency. however if the station operating on 90.5 mhz transmitter's power is 1.184 times or higher than that of the station operating on 107.1 mhz transmitter's power, then the 90.5 mhz signal will have higher energy because the additional photons makeup the difference. the total energy in electromagnetic radiation is the product of the energy per photon and the number of photons (i.e. amplitude of the wave) in the radiation.
