Mrac [35]

Answer:

CuBr₂(aq) + Pb(CH₃COO)₂(aq) → Cu(CH₃COO)₂(aq) + PbBr₂ (s)↓

Explanation:

We identify the reactants:

CuBr₂ and Pb(CH₃COO)₂

The products will be: Cu(CH₃COO)₂ and PbBr₂

You may know these information:

Salts from acetate are soluble.

Bromide can make solid salts with these cations: Ag⁺, Pb²⁺, Hg₂²⁺, Cu⁺

PbBr₂ is formed, so this will be our precipitate

The equation is:

CuBr₂(aq) + Pb(CH₃COO)₂(aq) → Cu(CH₃COO)₂(aq) + PbBr₂ (s)↓

Table below shows the electronegativities of four elements. Which of the following bonds is the most polar?
Contact [7]

 Lets find the electronegativity difference between the bonded atoms;

C-H = 2.6-2.2 = 0.4

C-F = 4.0-2.6  = 1.4

F-F = 4.0-4.0   = 0

H-O = 3.4-2.2  = 1.2

Here the electronegativity difference is highest for C-F bond hence C-F bond is most polar.
