Answer: I believe that it's electrons please let me know if it was right or what it was!
Hope this helps!!! Good luck!!! ;)
A. the density stays the same unless given an external catalyst
Answer:
Compound
Explanation:
-compound is a chemical substance composed of many identical molecules composed of atoms from more than one element held together by chemical bonds.
Answer:
The dimerization of butadiene to 4-vinylcyclohexene folows second order kinetics and its rate law will be given by :
![R=k[C_4H_6]^2](https://tex.z-dn.net/?f=R%3Dk%5BC_4H_6%5D%5E2)
Explanation:

The rate of the reaction ;
![R=k[C_4H_6]^x](https://tex.z-dn.net/?f=R%3Dk%5BC_4H_6%5D%5Ex)
As given in the question , that graph of time verses
was linear but plots of
or
was curved.
Generally:
Graph of time verses
for zero order reaction is linear with negative slope.
Graph of time verses
for secon order reaction is linear with negative slope.
Graph of time verses
for secon order reaction is linear with positive slope.
So, the dimerization of butadiene to 4-vinylcyclohexene folows second order kinetics and its rate law will be given by :
![R=k[C_4H_6]^2](https://tex.z-dn.net/?f=R%3Dk%5BC_4H_6%5D%5E2)
