Question

Jesse has a class project. She wants to show how CO2 from the atmosphere gets converted to carbonates. What kind of process would help her depict this? A. photosynthesis B. chemical processes C. litterfall D. natural processes

Answer 1

Answer;

-Photosynthesis

Explanation;

-Photosynthesis is referred to as the process where plants use energy from the sun, carbon dioxide, and water to make food. Photosynthesis is largely responsible for maintaining and producing oxygen content of the atmosphere of the earth and then supplies all organic compounds and energy which is necessary for life.

- Carbon dioxide may be removed from the atmosphere when it is used by plants and algae for photosynthesis, dissolved in water, or deposited in the sediments on land or in the ocean. During photosynthesis there is photosynthetic conversion of carbon dioxide into carbohydrates by plants, releasing oxygen in the process.

Answer 2

Answer:

B. chemical processes

Explanation:

The conversion of CO2 into carbonates is a type of chemical process.

A carbonate is a polyatomic ion with a chemical formula CO3^2- . From atmosphere CO2 can be easily converted into carbonates. Dissolution of carbon dioxide (CO2) into water (H2O) leads to the conversion of CO2 into carbonic acid (H2CO3) which comprises a carbonate ion. This carbonate ion then further reacts with either magnesium or calcium ion to produce calcium carbonate or magnesium carbonate which are carbonic salts of these metals.

The reactions are shown as under :

H2O + CO2 <=> H2CO3 (carbonic acid)

H2CO3 <=> H+ + HCO3^- (bicarbonate ion) <=> 2H+ + CO3^2- (carbonate ion)

Ca2+ + CO3^2- <=> CaCO3 (Calcium carbonate).

Similarly, magnesium can also react with carbonate ion.

Since each species is reacting chemically, these are regarded as a chemical process (chemical reactions).
