Schematic of carbon chemistry changes due to invasion of fossil fuel CO 2 into the surface ocean. Changes are shown as a stacked plot for the three different components of DIC, with changes in pH (solid line) superimposed. X-axis corresponds to increasing fossil fuel carbon from left to right, as fossil fuel invasion increases surface ocean DIC from an assumed pre-industrial value of 2000

[ Check the balance ] The thermal decomposition of calcium hydrogen carbonate to produce calcium carbonate, carbon dioxide and water. The reaction takes place in a boiling solution. Elimination temporary hardness of the water by boiling. Find another reaction
An equation is balanced by mass when the nuer of atoms of each element in the reactants equals the nuer of atoms of that element in the products. For example, the equation shown for the decomposition of water has four atoms of hydrogen in the two molecules of water on the reactant side and four atoms of hydrogen in the two molecules of hydrogen gas on the product side; therefore, hydrogen
