What volume of 0.436 M barium nitrate solution is needed to prepare 240.0 mL of a barium nitrate solution that is 0.300 M in nitrate ion? a. 349 mL
b. 82.6 mL
c. 55.0 mL
d. 165 mL
e. 330. mL

The answer should be vaporization 

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃  → 3 nicl₂ + 2 albarium and copper bromideba + cubr  →  no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al  → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn  → znso₄ + na
