10.00 mL of a solution containing 0.17 M NaCl and 0.23 M AlCl3 is introduced into a fully charged cation exchange column. How many moles of hydronium ions will be released by the column?
Evaluate the operating conditions of the chiller - what temperature must the chiller operate if the product streams are also at 1 atm total pressure?
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?
One isotope has a mass of 44.0 amu and has a neutral abundace of 69.5% while the other isotope with the mass of 46.08 amu.
When a 3.25 g sample of solid sodium hydroxide was dissolved in a calorimeter in 100.0 g of water, the temperature rose from 23.9 °C to 32.0 °C. Calculate ?H (in kJ/mol) for the solution process: NaOH (s) → Na+ (aq) + OH- (aq)
Atoms contain protons. 2)Nuclei move out of the paths of the alpha particles. 3)Neutrons have zero charge.
Why is mercury being replaced by other liquids such as colored alcohol as the temperature-sensing fluid
Iron(III) is polarographically reduced to iron(II)at potentials more negative than about +0.4V versus SCE and is further reduced to iron(O) at -1.5V (vs SCE). Iron(II) is also reduced to metal at -1.5V.
