To mitigate co2 emissions to the atmosphere some have suggested injecting co2 into deep groundwater. a groundwater initially at ph 8.3 with an alkalinity of 1x10-2m will have co2 injected until the groundwater comes to equilibrium with pco2=10 bar. before adding the co2, the groundwater behaves as a closed system. you can assume that activities are equal to concentrations. (a) what is the total inorganic carbon (ct) of the groundwater before co2 injection. (b) what are the alkalinity, total inorganic carbon (ct) and ph of the groundwater after equilibration with the injected pco2?

Imagine if during the cathode ray experiment, the size of the particles of the ray was the same as the size of the atom forming the cathode. which other model or scientific observation would have also been supported? 1. this would support dalton's postulates that proposed the atoms are indivisible because no small particles are involved. 2. this would support bohr's prediction about electrons moving in orbits having specific energy. 3. this would support bohr's prediction about electrons being randomly scattered around the nucleus in the atom. 4. this would support dalton's postulates that proposed that atoms combine in fixed whole number ratios to form compounds.
