Select the correct value for the indicated bond angle in each of the compounds.

90°, 180°, 109.5°, 120°, <120°, <109.5°

a) O−O−O angle of O3
b) F−B−F angle of BF3
c) F−O−F angle of OF2
d) Cl−Be−Cl angle of BeCl2
e) F−P−F angle of PF3
f) Cl−Si−Cl angle of SiCl4

Bond angle is defined as the angle between two or more bonds or bonded electron pairs in a compound.

Explanation:

a) O−O−O angle of O3 - <120°

b) F−B−F angle of BF3 - 120°

c) F−O−F angle of OF2 - <109.5

d) Cl−Be−Cl angle of BeCl2 - 180°

e) F−P−F angle of PF3 - 109.5°

f) Cl−Si−Cl angle of SiCl4 - 90°

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
