why do we add cyclohexene to the trans-stilbene with bromine in dichloromethane reaction mixture? what additional
Copper reacts with any oxygen present as an impurity in the ethylene used to make polyethylene. The copper is regenerated when hot H2 reduces the copper(II) oxide, forming the pure metal and H2O.
The equilibrium-constant expression for the below reaction is given by: Ti(s) + 2Cl2(g) yields TiCl4(l) a. [TiCl4(l)]/[Ti(s)][Cl2(g)] b. [Ti(s)][Cl2(g)]^2/[TiCl4(l)] c. [TiCl4(l)]/[Cl2(g)]^2 d. [Cl2(g)]^-2 e. [TiCl4(l)/[Ti(s)][Cl2(g)]^2
