If you take 25 mL of a 500 ppb solution and add sufficient water until the volume is 100 mL, and mix thoroughly what is the concentration of the final solution?You dilute 10.0 mL of a 2.50 M solution to 500 mL, what is the final concentration?
When calcium carbonate is added to the solution of organic acids, the following compounds form: calcium methanoate salt from the methanoic acid; calcium ethanoate from the ethanoic acid; and calcium phenoxide salt from the phenol.
The solubility of N2 in blood at 37°C and at a partial pressure of 0.80 atm is 5.6 10-4 mol/L. A deep-sea diver breathes compressed air with the partial pressure of N2 equal to 3.6 atm.
The molar stoichiometric ratio of nitrogen produced to ammonia reacted in the reaction equation is one to one, and the mol CO2/mol C6H12O6 = 2.
the rate of disappearance of HBr in the gas phase reaction 2HBr(g)-->H29(g)+Br2(g)is .301 at 150 degrees celsius. what is the rate of appearance of Br2?
How many millimeters of 1 N NaOH must be added to a 500-mL solution containing 500 mg of acetic acid to increase the pH to 5
In column chromotography, after adding ethanol, all of the methylene blue was washed away and after adding sodium hydroxide, all of the sodium fluorescine was washed away. Why did this happen
pH = log[H3O+] , pH + pOH = 14, [H3O+] * [OH-] = 1.0 X 10^-14, pH = -log(0.001) = 3 Could you show me a few of the steps between line one and two in both of these conclusions?

If you have 25 mL of a standard 1 mg/mL CaCO3 solution, how many mLs of the 0.010 M solution do you expect to use in the titration
Calculate the molarity and mole fraction of acetone in a 1.26 m solution of acetone (CH3COCH3) in ethanol (C2H5OH). (Density of acetone = 0.788 g/cm3; density of ethanol = 0.789 g/cm3.) Assume that the volumes of acetone and ethanol add.
If you look at a reaction equation for an esterification reaction, you cannot tell where the oxygen comes from (acid or alcohol). Knowing the mechanism of this reaction, devise an experiment using O18, to help prove unequivocally where the oxygen ..
