What is the change in the freezing point of water when 68.5 g of sucrose is
dissolved in 500.0 g of water?
k of water = -1.86°c/mol
molar mass sucrose = 342.30 g/mol
ivalue of sugar = 1
o a. 0.0186°c
o b. -0.215°c
o c. -0.744°c
o d. 0.254°c

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
