Structure can affect the Ka values for related acids. In the boxes below, draw the complete Lewis structure for a single ion of the conjugate base of each acid after the removal of a proton and consider the change in stability of the ion resulting from deprotonation. HINTS: Consider any increase/decrease in ability to participate in intramolecular hydrogen bonding as well as how the resulting –COO- groups in a molecule will interact with other atoms in the same molecule/ion.

a polar bond is formed when electrons are shared unevenly between atoms

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

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
