HELP ASAP!!I’ll put brainlist Lot of points

The bonds between the following pairs of elements are covalent. Arrange them
according to polarity, naming the most polar bond first. Draw the arrows properly
(Youcan "draw" arrows like this:+--->).
a. H-N = |
b H-C=
c. H-F
d. H-O
e. H-H

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z

answer

frequency, z, and the collision density, z, in carbon dioxide (co2), r 180 pm at 30 °c and 120 kpa

it would only be the stuff in module eight so you need to study all the lessons in that you also could check the flvs

hope this : )
