What is the residue of burned coal?
Ash
Why does burnt coal look white?
It is the residue (ash) which is left after the carbon materials are burnt off
What is coal ash made of?
Coal ash is the residue from burning coal and contains all of the nonvolatile components of he coal (carbon compounds, sulfur and some metals). The ash is made up of silicates, metals (including toxic metals like mercury and uranium) and some unburnt carbon.
Is petroleum coke the same as petroleum gas?
No. Petcoke (petroleum coke) looks like coal and can be burned in coal boilers with little adjustments. The difference lies in the composition and production: coal has less carbon contents, more ash and usually less sulfur. Coal is also obtined in mines while petcoke is the resulting residue of petroleum processing.
When a solution evaporates what may be left behind?
crystallized solute

Main constituent of bio gas is?
Methane is the answer, By the destructive distillation of coal, we can obtain coal gas, coal tar and ammonia. Coke is left as a residue. Coal gas contains methane, carbon monoxide and hydrogen. Since all the three are combustible, coal gas is a good fuel with a high calorific value.
What is coal ash made of?
Coal ash is the residue from burning coal and contains all of the nonvolatile components of he coal (carbon compounds, sulfur and some metals). The ash is made up of silicates, metals (including toxic metals like mercury and uranium) and some unburnt carbon.
What source is responsible for producing the most pollution?
The Coal is the major pollutants since it leave out residue in the form of ash and bituminous coal gives out huge smoke on ignition. Hence it pollute the environment.
What is the black solid that is formed in the combustion of hexane?
Coke, most likely. Coke is the carbonaceous residue left over from the thermal "cracking" of hydrocarbons (the term is also used to describe the residue left over from coal combustion).

Coal is also obtined in mines while petcoke is the resulting residue of petroleum processing.
What is the formula of Coal gas mixture?
The composition of coal gas varied according to the type of coal and the temperature of carbonisation. Typical figures were: Carbonization/Carbonisation is the term for the conversion of an organic substance into carbon or a carbon-containing residue. ... * Hydrogen 50% * Methane 35% * Carbon Monoxide 10% * Ethylene 5%
When a solution evaporates what may be left behind?
crystallized solute
When coal burn it leave ash behind. Ash so produced is lighter than the coal which has burnt. justify the decrease in mass in the light of law of conservation of mass?
During combustion carbon dioxide and water are released; ash is only the residue.
Chalk and cole is what type of sedimentary rock?
You are really going to confuse people if you use that spelling, but I figured out that you mean chalk and coal. I would describe their type as biological. Chalk derives from the shells of tiny marine organisms, and coal is a residue of plant matter.
What does the complete combustion of coal produce?
The complete combustion of organic compounds produces Carbon Dioxide (CO2), Water (H2O), and a residue of any impurities which were present in the coal before combustion. Complete combustion requires a great surplus of molecular Oxygen to occur.
