1.covalent bond
2A bond angle is the angle between two bonds originating from the same atom in a covalent species
3. 1.Write the Lewis dot structure for the molecule.
2.Use the steric number and VSEPR theory to determine the electron domain geometry of the molecule.
3. Use the VSEPR shape to determine the angles between the electron domains.
For the 1st one.
Echo means reflection of sound. Therefore the answer is a person looking in the mirror (as this is the only answer that does not hav refraction)
