Most plastics are made from oil or natural gas. One step in making plastics from these resources is called cracking. Cracking is

a process that breaks down bigger molecules into smaller ones. In one cracking reaction, ethane breaks down to become ethylene and hydrogen. During this process, thermal energy is absorbed from the surroundings and converted to chemical energy.

C10H22 > 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 %
