The variation of concentration of C O 2 in a large city should be predicted on the basis of given average concentration value of carbon dioxide. Concept introduction: Carbon dioxide is one of the major anthropogenic greenhouse gases and its concentration on a large scale, all over the world makes harmful effect to the earth and to the living systems on earth. Its concentration varies in accordance with the changes in season and climate in a particular area. Large increase in the number of automobiles, also enhance the concentration of carbon dioxide in a great extent. Parts per million (ppm): It is one of the important concentration expressing terms, and which describes grams of solute per million grams of total solutions. ppm = Mass of solute Mass of solution ×10 6

Question

15. Carbon dioxide makes up approximately 0.04% of Earth's atmosphere. If you collect a 2.0-L sample from the atmosphere at sea level (101.33 kPa) on a warm day at 27 °C, how many CO2 molecules are in your sample? * a. 5 x 10^20 b. 5 x 10^21 O c. 5x 10^22 d. 5 x 10^23

In Module #4, we discussed the role of chlorofluorocarbons (CFCs) in catalyzing the destruction of O3 in the stratosphere. One example of a CFC that is known to exasperate formation of the hole in the O3 layer is dichlorodifluoromethane (CF2Cl2). In the year 2000, this chemical reached its peak concentration of 2.2 x 10-11 M in the atmosphere. The destruction of CF2Cl2 can be approximated as a first-order process and the 1996 treaty on CFC emissions has eliminated its release into the atmosphere. Given that the rate constant for destruction of CF2Cl2 in the atmosphere is 0.009 yr-1, how long will it take for the concentration of CF2Cl2 to decline to 0.22 x 10-11 M?

19. The chemical equation for photosynthesis is _CO2 (g) + _H₂O (1)→ __C6H1206 (s) + (C6H12O6 is glucose, the simplest sugar) a. Balance the chemical equation above by filling in the blanks. b. According to onetreeplanted.org, the average tree (across all climates and sizes) removes 10 kg of carbon dioxide from the atmosphere every year. Based on this, what mass of glucose is produced annually by the average tree? O2 (g) c. Teak is a common species of tropical tree. The graph below shows the amount of CO₂ absorbed by teak forests in tons of CO₂ per hectare of forest per year, according to the climate region where the forests are found (dry = low rainfall, humid=high rainfall). Looking at your photosynthesis equation again, what does this data suggest about which reactant is the limiting reactant for teak trees? Explain.
