Acetylene tetrachloride (Westron), CHCl 2 ·CHCl 2 It is as well called as sym. tetrachloroethane. It is made by the action of chlorine on acetylene in existence of a catalyst
it is impossibe to synthesise orgnic compounds in the lab since life force is essential for their formation -theory is known as
The equilibrium cell potential of the galvanic cell Pt | H 2 (g, f =1 bar) HCl (aq, 0.500mol kg -1 ) | Cl 2 (g, f =1 bar) | Pt is found to be E cell, eq = 1.410V at 298.15
Any chemical species that has a tendency to accept electrons and thereby undergoing reduction themselves is known as an oxidizing agent
In an electrochemical cell a redox reaction perform in two halves. Electrons are liberated by the oxidation half reaction at one electrode and go through an electrical circuit
2p orbitals have : (1) n=1, l=2 (2) n=1, l=0 (3) n=2 l=1 (4)n=2, l=0 Ans: n=2 l=1
redox reaction of ethanal,caustic soda&copper hydroxide
Q. How to Replace Metals from their Salts: Ans. If zinc is added to a solution of copper (II) sulfate, it dissolves. A reddish-brown deposit of metallic copper appears,
