Crystals of calcium carbonate are being deposited on a fiber that is suspended in a suspension of bulk concentration of 50 g/l. the flow velocity is 0.01 m/s and the fiber has a diameter of 1 mm. determine the deposition rate of the crystals to the fiber surface if the crystal diffusivity in water is given as 1.5e-12 m2/s. the solutions are aqueous. the length of the fiber is 5 mm

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.

practical process described pest part of scientific investigation.

because practical knowledge is powerful then therotical knowledge.

thats how its supposed to be
