yes it is balanced

by cartels in other countries, shipped by air, mail, or land. i cant really see your answer choices : /

it means there are 3 atoms of oxygen

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
