no lead is an element and tetraethyl is an organic (or carbon) compound.
When gasoline was leaded prior to 1995 (US) the combustion of gasoline containing lead tetraethyl was helped along by the addition of an organobromine compound, 1-2 dibromoethane, that formed lead bromide in combustion , which came out in the exhaust gas. Hardly a use but that was probably the only time most people would encounter this chemical.
1 kg of water. Water is less dense than lead. This means that the same volume of water will be lighter than the same volume of lead. Reversing this, 1kg of water will have a larger volume than 1kg of lead.
In solid form you can simply sift the dirt and lead mixture through a sieve-like tool, with the help of a little water to wash the dirt through. The lead will be too big to be washed through the tiny holes. In mineral form, where the lead is the same grain size as the dirt, you will simply have to plant lead-absorbing plants in the dirt, which will absorb the mineral lead.
graphite in a pencil and diamond are from carbon .both are the allotrope of carbon
Lead is less reactive than copper, so the sulphate ion would stay bound to the copper, so the answer is the same compounds as you started with.
Tetraethyl lead has 29 atoms in one molecule.
petrol additive
To prevent knocking.
Lead - in the form of Tetraethyl Lead
Tetraethyl lead is harmfull for the human beings, though it makes the car enigine more smooth to drive. In an extreme case, it can cause death to a person.
Tetraethyl lead has 4 ethyl groups attached to the lead atom.
tetra-ethyl lead means lead and ethyl taken four times in ethyl 7 atoms will be present there fore in tetra ethyl 28 atoms will be present.i9n tetra-ethyl lead 1 lead atom will be present so in total 28+1=29 atoms will be present in tetra-ethyl lead.
It can be improved by adding "TEL" which is tetraethyl lead having formula (C2H5)4Pb.
Tetramethyl lead: 4CH3Cl + Na4Pb -------------> (CH3)4 Pb + 4NaCl Ttraethyl lead : 4CH3CH2---Cl +Na4Pb ---------------> (CH3CH2)4Pb +4NaCl
Tetraethyl lead was phased out of gasoline in the United States starting in 1976 and ending in 1986. Leaded gasoline caused lead to be present in automotive exhaust, which caused an increase in the lead content in people's bloodstream, which tends to reduce I.Q. and increase antisocial behavior. Tetraethyl lead was used as an octane improver, and it also reduced valve seat wear. It damages catalytic converters, which are the primary emission control device in motor vehicles. Catalytic converters and hardened valve seats started being produced in 1975.
Yes, Lead is good. Your valves could be damaged by using unleaded. Try http://www.batterystuff.com/fuel-treatments/OS6q.html This is real tetraethyl lead, the good stuff.
