Burning one pound of carbon releases about 3.6 pounds of carbon dioxide (the extra weight comes from oxygen from the air).
Around 3 pounds of CO2 are emitted by open air burning of one pound of tire.
453.6 grams of CO2 make 1 pound dry ice. Farhat Azim
Approx. 50 USD/pound for thorium dioxide (99,99 %).
You can purchase dry ice (frozen CO2) from your local grocer for about $1.50 per pound. Canisters of the compressed gas range in price, depending on the application. CO2 cartridges for air rifles may cost 50 cents each. Soda machine CO2 canisters have a wide range in price, as do the big compressed air bottles used by heavy industry.
Aluminium cannot be extracted by reduction with carbon as aluminium is more reactive than the carbon. Instead electolysis must be used, which is a much more expensive method of extracting a metal from it's ore.
Around 3 pounds of CO2 are emitted by open air burning of one pound of tire.
The reaction is: C + O2 = CO2 The volume (or the mass) of the released carbon dioxide depends on the concentration of carbon in charcoal; this is very variable.
Burning of (any amount of ) coal is a chemical change.
First, it should be understood that the gallon of gas will not create any carbon. All the carbon due to the gallon of gas is already there, in and part of the gas(oline). It amounts to about 12/14 of the gasoline, so the carbon content of a gallon of gasoline is 12/14 of 6.2 lb (wt of a gallon of gasoline), or about 5.3 lb of carbon. It will still be 5.3 lb of carbon even if you burn it, since matter is not destroyed in a chemical reaction. If the question is how much carbon dioxide, the simplest answer is that there is about 3.2 times as much carbon dioxide produced in burning alkanes (like octane) as the weight of the alkane. A gallon of gas weighs about 6.2 lb and will combine with oxygen to make about 3.2x6.2 or 20 lb of CO2.

-- Candles must be manufactured. You can't just dig them out of the ground in a usable form. -- Coal contains more chemical energy than candles do. You get more energy from burning a pound of coal then you get from burning a pound of candles. -- On the other hand, a power plant that burned candles would operate cleaner than one that burns coal. It might produce just as much carbon dioxide, but I suspect that there might be less sulfur and mercury to worry about.
because it has long roots that rich over the pound
Greenhouse gases (GHG) are those gases which absorb solar radiation and re-radiate the heat into the atmosphere. The principal gases in this category are carbon dioxide and methane.Human activities which lead to these emissions or decreased activity of GHG sinks are:Burning of fossil fuelsAgricultural practices (cattle related methane emissions and loss of carbon sequestration in soil by modern tilling practices)Reduction of forest coverMethane leaks from oil and gas fieldsJust keep doing what we are already doing will do that (e.g. burning lots of fossil fuels, heavy logging).
Depends on your understanding of the term "biggest":The largest volume of naturally occurring greenhouse gas is water vapour.The largest volume or tonnage of manmade greenhouse gases is carbon dioxide.The most potent is Sulfur Hexafluoride (SF6) which has a greenhouse gas impact 23,900 times that of carbon dioxide.
Natural gas is a fossil fuel (mostly). If it is methane CH4 it burns with oxygen to produce CO2 and H2O (carbon dioxide and water): Each carbon atom combines with two oxygen atoms, while every pair of hydrogen atoms combine with a third oxygen atom. Every pound of fuel burned creates 2¾ pounds of carbon dioxide.
