The formula for ethanol is CH3CH2OH
So for each mole of ethanol burnt it produces 2 moles of carbon dioxide
1 Mole of ethanol is 46 g
2 moles of carbon dioxide is (2 x 44 g) 88 g
So each gram of ethanol produces 1.9 grams of carbon dioxide on combustion
It costs very little to produce carbon dioxide as it is a byproduct of many industrial processes. The cost depends on the specific method used, but it is generally a small fraction of a cent to produce 9oz of carbon dioxide.
22 grams of carbon dioxide contains 12 grams of carbon. This amount of carbon can combine with 32 grams of oxygen to form 44 grams of carbon dioxide.
Respiration (breathing) has no effect on the amount of carbon dioxide in the atmosphere. Breathing is part of the carbon cycle. We take in carbon in our food and drink and we release it again when we breathe. If we eat too much, the extra carbon is stored in our bodies, making us fatter, in much the same way as a tree stores carbon in its wood as it grows.So breathing does not increase or decrease the amount of carbon dioxide in the atmosphere.
Photosynthesis is the main process in the carbon cycle that decreases the amount of carbon dioxide in the atmosphere. During photosynthesis, plants take in carbon dioxide from the air and convert it into carbohydrates and oxygen. This helps to store carbon and reduce the overall concentration of carbon dioxide in the atmosphere.
On average, a plant can absorb about 1/3 of a pound (150 grams) of carbon dioxide in a day.
Assuming the fuel is 100% ethanol the reaction is: C2H5OH +3O2 --> 2CO2+3H20 or 1 mole of ethanol (46 g) creates 2 moles (44 x 2=88) of carbon dioxide The density of ethanol is 0.78 g/cm3 or .78 kg/L So the amount of carbon dioxide created by a car fueled by ethanol is about 1.56 kg/liter used. This excludes CO2 from ethanol manufacture.
C + O2 -------> CO2 12g of carbon produces 44g of carbon dioxide 1kg of carbon will produce 3-67kg of carbon dioxide
First of all, you have to understand that the whole grain-ethanol thing is more of a back-door subsidy for corn farmers than an environmental initiative. That said, I'm not sure that either method of making ethanol results in a net reduction of carbon dioxide in the atmosphere. In the case of grain ethanol, it takes fossil fuels (in the form of diesel) to grow the corn. And some estimate that it takes more diesel fuel just to grow the corn than will be replaced by the resulting ethanol. So, you would be better off, in terms of fossil fuel usage, to just burn the diesel in cars and trucks. But fossil fuels are not the only fuels that put carbon dioxide into the atmosphere. Burning ethanol also releases carbon dioxide. Maybe not as much as fossil fuels, but whatever it produces would have to be added to the carbon dioxide that was produced in growing the corn. And that is most certainly more than the carbon dioxide that would have been produced by burning the fossil fuel directly in automobiles. In the case of uncultivated biomass, you don't have tractors and other fossil-fuel-burning equipment contributing to the carbon dioxide in the atmosphere. However, the process of converting uncultivated biomass to ethanol is much more energy-intensive than converting grain to ethanol. So you still have quite a bit of fossil fuel burning required to produce the ethanol. And you still have all the carbon dioxide released when the ethanol itself is burned.
Ethanol is a fuel made from plants. When we burn this fuel, it does emit carbon dioxide, but of course this was originally absorbed from the atmosphere by the plants, so there is no net increase in the amount of atmospheric carbon dioxide no matter how much ethanol we use (apart from a small amount produced by generating electricity used in the production of the ethanol). A disadvantage of using ethanol for motor fuel is that its production competes with food crops.
On average 258.63g of Carbon Dioxide a day
Cars produce much more than houses.
Any automobile produces about 2 kilograms of carbon dioxide per liter of fuel consumed.
Typically 2.31 kg.
Yes. Your carbon footprint is the measure of how much carbon dioxide equivalent you, or any of your activities produce. A car burns petrol (gasoline) so its use has a carbon footprint.
The oceans are regarded as carbon dioxide sinks, not sources. This means they remove carbon dioxide, not produce it. Carbon dioxide dissolves from the air into ocean water. Once there it is removed by plankton and algae, by corals and mollusks in making shells, and by chemical action.
Yes, but at night. It make oxygen more than it does carbon dioxide though. ---- Plants, like animals, do have metabolisms by which energy is generated through the oxidation of sugar, which produces carbon dioxide. However, green plants consume much more carbon dioxide, in the process of photosynthesis, than they produce by means of their metabolism, and they produce much more oxygen than they consume.
No, it's the other way around. Plants intake Carbon dioxide and put out Oxygen. In the theory of how the world formed, this is how the atmosphere got to contain Oxygen, from plants spreading over the continents and producing Oxygen.
