Organic Chemistry: Don’t Panic
Respiration
O2 + CHO2 → H2O + O2 + energy
Photosynthesis
H2O + CO2 + energy → O2 + CHO2 (carbohydrate)
Formation of Limestone
H2O + CO2 → O2 + H2CO3 (carbonic acid)
H2CO3 + H2O + silicate minerals → HCO3 (bicarbonate) + Ca++ + clays
Ca++ + 2 HCO3 → CaCO3 + CO2 + H2O (thank you coral!)
