1. How are seasons connected to the annual CO2 cycle?

Biology
1 answer:
KengaRu [80]3 years ago
5 0

CO2 in the atmosphere decreases during the growing season and increases during the rest of the year, which leads to maximum buildup in April and May before photosynthesis begins to take over again.

There's more carbon dioxide in the winter and a bit less in the summer. That's the collective breathing of all the plants in the Northern Hemisphere. "Plants are accumulating carbon in the spring and summer when they're active, and they're releasing carbon back to the air in the fall and winter," Graven explains.

We are reacting two molecules of nitrogen gas with six molecules of hydrogen gas to form ammonia, nh3
pentagon [3]

To form ammonia, we can react 2 molecules of N₂ with 6 molecules of H₂. Once the reaction has completed, the total molecules of each gas will be: 1 molecule of nitrogen, 3 molecules of hydrogen, and 4 molecules of ammonia.

<h3>How to predict the total molecules of reactants and products?</h3>

The formation reaction of ammonia needs one molecule of nitrogen and 3 molecules of hydrogen. The reaction is as shown in the equation below:

N2(g) + 3H2(g) --> 2NH3(g)

2N2(g) + 6H2(g) --> 4NH3(g)

They will form a new product as four molecules of NH₃. Speaking in the present time after the reaction has completed, half of the reactants (N₂ and 3H₂) are gone to form the ammonia. Hence, the correct answer is: 1 N₂, 3 H₂, and 4 NH₃.


This question seems incomplete. The complete query is as follows:

"We are reacting two molecules of nitrogen gas with six molecules of hydrogen gas to form ammonia, NH₃. How many molecules of each type of gas will be present once the reaction has completed?"

What does the presence of pillow lava says about the place?
allsm [11]

Answer:

The presence of pillow lavas in the oldest preserved volcanic sequences on the planet, the Isua and Barberton greenstone belts, confirms the presence of large bodies of water on the Earth's surface early in the Archean Eon. Pillow lavas are used generally to confirm subaqueous volcanism in metamorphic belts.

Hope this helps :)
