Question

QUESTION 1 CO2 is absorbed more easily in: High salinity Low Salinity O Cool waters O Warm waters QUESTION 2 What happens when CO2 dissolves in water? CO2 + H20 = O CO32- + 2 H+ HCO3 - + H+ HCO3- + H20 O C6H1206 QUESTION 3 How much of the excess Anthropogenic heat has been taken up by the oceans? O 90% 25% 70% O 50%

Answer 1

1. Cool water.

Generally CO2 more absorbs in cool water. Because CO2 gas is a warm gas. So it easily absorbed with cool water. In earth more Co2 absorbs in polar regions than equatorial regions . Because polar region of ocean water is low temperature than equatorial ocean water.

Low salinity water absorbs more CO2 than high salinity water.

Warm water absorption low amount of co2 than cool water.

2. HCO3- + H+

When CO2 reacts with H2O reaction will be

CO2 + H2O = HCO3- + H+

3. 90%

Anthropogenic heat mainly green House gases dissolved by ocean is 90% . As a result rise of oceanic temperature.
