Water-soluble barium salts are toxic to humans. Potassium sulfate and magnesium sulfate are used as emergency treatments for barium chloride poisoning. These work by reacting with the barium chloride to form barium sulfate. Barium sulfate is less dangerous due to its insolubility in water.
Best Answer: Photosynthesis: 12 H2O + 6 CO2 -> 6 O2 + C6H12O6 + 6 H2O. 12 water molecules and 6 carbon dioxide molecules are the reactants. 6 oxygen molecules, 1 glucose molecule, and 6 water molecules are the products. Light dependent reaction happens at the thylakoid membrane, made up of lipid bilayers, which is conveniently located in the chloroplast -> Light-independent reaction (the Calvin-Benson Cycle) happens in the stroma -> creation of glucose molecule.
During the light reactions of photosynthesis, light from the sun is captured through a series of reactions involving the chemical chlorophyll. This results in the synthesis of two high energy chemical compounds: ATP and NADPH, the latter whose chemical energy is held by electrons that can be transferred easily to other compounds. This set of reactions requires water (H2O) from which oxygen is released during the process. ATP and NADPH are used subsequently to produce glucose from CO2 in the next phase of photosynthesis, the dark reactions.
