It could be characterized by “single displacement reaction” because in a chemical reaction one element replaces another element in a compound and is known as a single displacement reaction. And only one element has been displaced so thats why the word "single" is used also

The electronegativity is 2.1 for h and 1.9 for pb. based on these electronegativities pbh4 would be expected to
Sedbober [7]
PbH4 will be formed as a result of a polar covalent bond between the H and the Pb.

Since H is more electronegative than the Pb, it is, thus, expected that the H would be able to pull the electron charge towards itself. This will result in the H being negative.

Based on this:
PbH4 would be expected to <span>have polar covalent bonds with a partial negative charges on the H atoms. </span>

C10H22 &gt; C8H18+C2H4 if only ethane can be sold what is the atom econmy of this process
insens350 [35]

Answer:

The atom economy of ethane in this process is 19.72 %.

What is atom economy?

The conversion efficiency of a chemical reaction in terms of all the atoms involved and the desired products produced is known as atom economy (atom efficiency/percentage).

Explanation:

C₁₀H₂₂ → C₈H₁₈ + C₂H₄

Molecular weight of C₁₀H₂₂ = 142.28

Molecular weight of C₈H₁₈ = 114.228
Molecular weight of C₂H₄ = 28.053

% Atom economy =     \frac {Molecular weight of C2H4} {Molecular weight of C10H22}

                             = \frac{28.053}{142.28}*100

                             = 19.716 %

                             ≈ 19.72 %
