So long as atmospheric CO 2 concentration is increasing there is net uptake of carbon by the ocean, driven by the atmosphere-ocean difference in partial pressure of CO 2. The fraction of anthro-pogenic CO 2 that is taken up by the ocean declines with

www.cerritos.eduIn fact, atmospheric water in the lab can dictate one's success when trying to synthesize a Grignard reagent from magnesium turnings and an alkyl halide. To circumvent this issue, the reaction vessel is often dried to evaporate all moisture, and then sealed to prevent more from entering. Grignard reactions often start slowly.
