In a non-biological system, given the equation CO2 + H2O ⇌ H2CO3 ⇌ HCO3- + H+ , what would happen to the amount of CO2 if HCO3- was taken away or removed in some way? (Hint: In chemistry, the concept is known as Le Chatlier's Principle)    The amount of CO2 will increase to compensate for the lost HCO3- The amount of CO2 will decrease to compensate for the lost HCO3-  The amount of CO2 will stay the same

Glucose is a six-carbon compound. How many molecules of carbon dioxide will be released in a complete breakdown of a molecule of glucose?

The U.S. Environmental Protection Agency estimates that 2.4 kilograms of CO2 are released when 1 liter of gasoline is burned (20 pounds of CO2 are released when 1gallon is burned). Use this information to determine the number of metric tons of CO2 emitted annually by (a) the car described in Question 1 with a low fuel efficiency, (b) a fleet of 250 million vehicles with this same fuel efficiency, (c) the car described in Question 2 with a high fuel efficiency, and (d) a fleet of 250 million vehicles with this same high fuel efficiency. These calculations provide a rough estimate ofthe CO2 footprints for individual cars and for the entire U.S. fleet with low and high efficiency cars. (Note: 1 kilogram= 2.20 pounds; 1 metric ton = 1,000 kilo grams = 2,200 pounds = 1.1 tons; 1 ton [H11005] 2,000 pounds).
