Gains carbon dioxide (CO 2 ) from the soil, becoming more acidic. C. Neither gains nor loses carbon dioxide (CO 2 ). D. Gains humic compounds from the air, becoming a strong base. E. None of the other choices here is even close to being correct. CO 2 is fairly soluble in water. Lots of things living in the soil emit carbon dioxide, and soils contain a lot of carbon dioxide that helps make water acidic. Humic compounds are picked up from soil by water, and make the water more acidic. Points Earned: 1/1 Correct Answer: B Your Response: B 2.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
