MEDC basically means the country have education, good water supply,health care and high transportation. While LEDC means the county are very less education, but it doesnt mean they have no education. It means they have but less.
Ethane (/ËÉÎ¸eÉªn/ or /ËiËÎ¸eÉªn/) is an organic chemical compound with chemical formula C 2 H 6. At standard temperature and pressure, ethane is a colorless, odorless gas.Ethane is isolated on an industrial scale from natural gas, and as a byproduct of petroleum refining.Its chief use is as petrochemical feedstock for ethylene production.lthough ethane is a greenhouse gas, it is much less abundant than methane and also less efficient relative to mass. It has also been detected as a trace component in the atmospheres of all four giant planets, and in the atmosphere of Saturn 's moon Titan.
Ethane is a hydrocarbon gas made from petroleum. It is the second (first is methane) in a series of simple hydrocarbon petrochemical compounds in a family of related compounds named âAlkanesâ, all of which have the feature of containing only single bonds between carbon atoms. The chemical formula for ethane gas is C 2 H 6. 2  Ethane is a hydrocarbon that exists in nature as an odorless and colorless gas at standard temperature and pressure. 3  It is a stable compound and shows resistance to reactivity. 4  It has a molar mass of 30.07 grams per mole (g/mol).
