Pink Himalayan salt is advertised to include 84 trace minerals and elements. To name a few, uranium is reported at 0.001 ppm and platinum at 45.0 ppm. For simplification, assume that it is good enough to approximate the molar weight of the salt as NaCl. How many grams of salt would hypothetically you have to dissolve in 500. mL of water to obtain a concentration of uranium above the EPA's limit of 30.0 x10 M? U is found at 0.001 ppm which is the same as 0.001g U/10^6 g NaCl, how many grams of NaCl do I need to get the desired quantity of U? 3.57*10^4g O 3.57 10^6 g 3.57'10^7 g 3.57 10^5g

How can you aid in the dissolution of the potassium hydroxide (KOH)? Gentle heating on the hot plate Placing the beaker in an ice bath Stirring the solution Restarting with new pellets
25.0 mL of 1.00 M NaCl and 35.0 mL of 0.848 M AgNO3 are combined in a beaker. Write a balanced equation for the process that occurs, including the state of matter for each compound, and the net ionic equation for the reaction.
A 30.0 mL aliquot of 0.300 M H_3 PO_4 is mixed with 90.0 mL of 0.200 M KOH, and the mixture is evaporated. Will the salt that crystallizes out be K_3 PO_4, K_2 HPO_4, or KH_2 PO_4? Show your calculations by using an ICE table (or two or three). H_3 PO_4(aq) + KOH_(aq) rightarrow KH_2 PO_4(aq) + H_2 O (l) The next proton on the H_2 PO_4^- would start to react only when more OH^- was added, over and above the first mole: KH_2 PO_4(aq) + KOH_(aq) rightarrow K_2 HPO_4(aq) + H_2 O (I) The final proton on the HPO_4^2- would start to react only when more OH^- was added, over and above the second mole: K_2 HPO_4(aq) + KOH_(aq) rightarrow K_3 PO_4(aq) + H_2 O (I)
Carbonyl fluoride, COF2, is an important intermediate used in the production of fluorine-containing compounds. For instance, it is used to make the refrigerant carbon tetrafluoride, CF4 via the reaction 2COF2 (g) CO2(g) + CF4 (g), Kc = 4.80 If only COF2 is present initially at a concentration of 2.00 M, what concentration of COF2 remains at equilibrium?
