You are comparing the results obtained from the analyses of two different pens. You find that each pen has blue ink and that both blue inks have a similar λmax range. However the blue inks have substantially different Rf values. Could these two blue inks be the same substance? Why or why not?

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
