For a solution having 1.00 X 10^-3 equivilants/L total alkalinity (contributions from HCO3-, CO3^2-, and OH-) at [H+] = 4.69 x 10^-11, what is the percentage contribution to alkalinity from CO3^2-?
The total mass of pure metals produced = 0.4684 grams. compute the mass percent of CuCl2, and AgNO3, FeCl3 in the original mixture.
What makes a red solution, like cherry Kool-Aid appear red to your eye? What colors of light are absorbed and what colors are transmitted?
First determine the number of moles of rm Na^+ using the given molarity and volume. Next, use the chemical formula to determine the number of moles of rm Na_3PO_4 needed. Finally, convert moles to grams using the molecular weight of the compound.

A sample of a dish from an archaeological dig gave 18 500 disintegrations per gram of carbon per day. A 1.00-g sample of carbon from a modern source gave 22 080 disintegrations per day.
A piece of charcoal from a tree killed by the volcanic eruption that formed the crater in Crater Lake (in Oregon) gave 7.0 disintegrations of carbon-14 nuclei per minute per gram of total carbon.
The solubility product for Pb3(PO4)2 is 1.0 x 10^-54. write out the solubility reaction equation explaining why it is set up that way using the solubility rules or else I will not really understand how to set up the problem.
