Answer to Question 1

C

Answer to Question 2

Because when we combine the equations for carbonate weathering for CaCO3 and precipitation to determine the net effects of these processes on the chemistry of the oceans and on the composition of the atmosphere, we have got no net removal of carbon dioxide from the atmosphere. The net effect of CaCO3 weathering on land and CaCO3 precipitation in the ocean is zero, because the two processes balance each other:

Carbonate weathering:
CaCO3 + H2CO3  Ca2+ +2HCO3 -

Carbonate precipitation:
Ca2+ +2HCO3 -  CaCO3 + H2CO3

Net result: 0

The weathering equation is the reverse of the precipitation equation.
