I'm studing Cellular Respiration. We did a lab. We had technical difficulties... our CO2 gas sensor wasn't working properly. So I am curious, what trends SHOULD I have seen. We compared the CO2 output of bean sprouts vs mealworms. We tested at both room temp (27 degrees C) vs cold temp (15 degrees C) for both the mealworms and bean sprouts. I need to know the trends I should have seen, ie. does an animal or plant produces more C02 and why? Also does the the cool temp make the reduction in CO2 production? Thank you.

2. Two test tubes were filled with a solution of bromothymol blue. This solution turns yellow in the presence of carbon dioxide. An aquatic green plant was placed into each tube. A student exhaled through a straw into each tube and the bromothymol blue turned yellow. The tubes were corked and one tube was placed in the dark, the other tube was placed in direct sunlight. The yellow solution in the tube in sunlight turned blue, while the one in the dark remained yellow. Which statement best explains why the solution in the tube placed in sunlight returned to a blue color? A. Oxygen was produced by photosynthesis. Carbon dioxide was removed by photosynthesis. Carbon dioxide was produced by respiration. В. C. D. Oxygen was removed by respiration
w i 1) Destruction of the ozone layer takes place when its component ozone (03) is converted O3 + 0202 into oxygen gas (O2) as shown by the following chemical equation. Although degradation of O3 happens naturally, there are some man-made substances that cause this process to take pla ce at a rate which is harmful to the environment. One such substance is chlorofluorocarbon or CFC. In the presence of ultraviolet (UV) radiation, a de chlorine (Cl) atom from CFC reacts with O3 and converts it to 02 at a faster rate. This is Cl + O3 → Clo + O2 Clo + 0- Cl + O2 shown by the 2 equations below. In this process, the chlorine atom acts as 2) Pepsin is an enzyme present in gastric juice.

Explain how these factors: the size of bioaerosol, inspiratory flow rate, flow pattern, inhaled volume, respiratory rate influence the respiratory degration of bioaerosols.
2. Synthesis gas, a mixture that includes the fuels CO and H2 is used to produce liquid hydrocarbons and methanol. It is made at pressures up to 100. atm by oxidation of methane followed by the steam re-forming and water-gas shift reactions. Because the process is exothermic, temperatures reach 950-1100°C, and the conditions are such that the amounts of H2, CO, CO2, CH4, and H20 leaving the reactor are close to their equilibrium amounts in these reactions: CH4 (g) + H20 (g) CO (g) + 3 H2 (g) CO (g) + H2O (g) 5 CO2 (g) + H2 (g) (steam re-forming) (water-gas shift) Calculate the AH°, AS°, AG°, and K (at 298 K) for these two steps in this industrial a. process b. Assuming relatively little change in H or G, what is S for these two steps at 1000.°C? C. If the overall reaction for these two reactions is: 2 CH4 (g) + 3 H2O (g) 5 CO2 (g) + CO (g) + 7 H2 (g) Using standard molar formation thermodynamic values, is this reaction spontaneous at 1000.°C?
