The element is Carbon 3. What are two natural processes which have the greatest influence on the element’s concentrations on Earth and how do they function?

4. What are the two largest exchange pools and reservoirs (possibly called a “sink” on some websites) for the element?

7. What laws or restrictions exist to mitigate anthropogenic impact on the cycle and connect it to the importance for the regulation? If there are none, create one and explain why it is important to regulate.

Does anyone know a lot about how to: - calculate mass of magnesium metal - calculate the actual yield of magnesium oxide - calculate the theoretical yield of mgo - calculate the percent yield of mgo - determine the percent yield of mgo - determine the average percent yield of mgo i had to do an online lab and its asking these questions but i have no idea where to start or how to be able to find these things. i can post the chart of the data from the lab or if you can tell me exactly how i can find each.
