Answer: The Hummer H2 gets really poor gas mileage, somewhere in the range of 10 to 12 mpg. The Bugatti Veyron gets only 10 mpg, but it probably emits less CO2 overall as these tend not to be driven as much as the H2.
When something is burned (such as fuel, which contains carbon), a reaction takes place. Light, heat and physical force (in the case of an engine) are produced and oxygen is added. Recall that matter is not created nor destroyed, only converted. So when we add oxygen, it combines with the carbon to produce either carbon monoxide (one carbon one oxygen) or carbon dioxide (one carbon two oxygen).
Answer: not too sure what you want to know but i will explain the combustion process as best i can. gas car engines are a 4 stroke engine. the 4 strokes being: intake (down), compression (up), power (down), exhaust (up). engines operate off a reciprocating motion meaning the movement of one piston is the result of the opposite movement of a different piston. on the intake stroke the intake valve opens allowing fuel that has been mixed with air to be sucked into the cylinder by the downward travel of the piston (suction). on the compression stroke both the intake and exhaust valves are closed the piston travel back up with the air/fuel mixture in the cylinder. this compresses the air/fuel until he piston is at or near top dead center. then the spark from the spark plug ignites the air/fuel which causes a rapid expansion (not and explosion) or the air fuel thus pushing the piston down creating the power stroke. then the piston travels back up as the exhaust valve opens. the piston effectively pushes the spent air/fuel out of the cylinder. this is the basic principles of a internal combustion engine. now to more directly address your question. carbon monoxide is a by product of the air/fuel being burnt. the carbon monoxide (along with hydrocarbons and oxides of nitrogen) are pushed out on the exhaust stroke and into your exhaust system. it is the job of the catalytic converter to convert the carbon monoxide into carbon dioxide (a less harmful substance) it does this thanks to its chemical make up and elements that add an additional oxygen to monoxide to make it dioxide. its basically a filter for your exhaust.
Answer: 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.
Answer: The same hemoglobin molecules that absorb oxygen in the lungs release it to the cells in the capillaries and pick up carbon dioxide from the cells. When the blood returns to the lungs, the hemoglobin releases the carbon dioxide and replaces it with fresh oxygen. The carbon dioxide released by the hemoglobin travels across the membranes in the lungs and is breathe out when we exhale.
Answer: A gallon of gasoline releases 14 lbs of CO2 when burned. A car that averages 20 miles per gallon and is driven a typical 15,000 miles per year will burn 750 gallons, emitting a little over 5 tons of CO2.
A typical automobile emits about six tenths (0.6) pounds of CO2 per mile driven.
Answer: Carbon dioxide narcosis occasionally occurs when somepatients with hypercapnia are given oxygen to breathe. Arterialcarbon dioxide tension (Pa CO2)increases sharply and progressively with severe respiratoryacidosis, somnolence, and coma.
