Answer:
melting point,boiling point ,density,refractive index.
Explanation:
Fe2(SO4)3 + 6KOH -> 3K2SO4 + 2Fe(OH)3
Answer:
0.034 M
Explanation:
1/[A] = kt + 1/[A]o
[A] = ?
k= 0.04556
t= 10.0 minutes or 600 seconds
[A]o = 0.50 M
1/[A] = (0.04556 × 600) + 1/0.50
[A] = 0.034 M
number of moles of HI = 1.7 mol
number of moles of ZnBr2 = 3.43 mol
2HI + ZnBr2 → 2HBr + ZnI2
every 2 mole of HI will require 1 mole of ZnBr2
mole of ZnBr2 that will react = 1.7 / 2 = 0.85 mol
Therefore HI is the limiting reactant and not all ZnBr2 will be reacted
For every 2 mole of HI will form one mole ZnI2
1.7/2 = 0.85 mol of ZnI2 formed
