2, Carbon is stored in many places near Earthʹs surface. where you can find the most of the carbon?
A, geologic deposits
B, forests
C, animals
D, glaciers
E, lakes
Homework Answers
1) Option E, None of the above
The amount of total sunlight is very large and small portion of it is fixed in photosynthesis. It doesn't fix nitrogen but carbon. Oxygen is not a component of Photosynthesis but a by-product of this process. So answer is none of the above.
2) Option A, Geologic Deposits
Among the options given above the largest amount of carbon is stored in the lithospheric rock formations which is trapped from atmosphere.

Which of the following is not true? Catalytic converters can facilitate both oxidation and reduction reactions simultaneously. Catalytic converters that reduce the nitrogen in NO can also reduce the sulfur in SO2, resulting in production of the toxic gas H2S when sulfur is present in the fuel. Reduction of the nitrogen in NO (to yield N2 and O2) is energetically favorable, but because the activation energy is high, the reaction must either be catalyzed or done at high temperatures to...

Which of the following about equilibrium constant of a reaction are true. It can change if the concentration of reactants and products are changed. It can be used to calculate the biochemical standard free energy change (Delta G degree). It can be used to calculate the actual free energy change (Delta G). It is the same as the mass action ratio (Q) when the reaction is in equilibrium. It is always a constant regardless of temperature change. Which of these...
