An automobile radiator is filled with an antifreeze solution prepared by mizing equal volumes of ethylene glycol, C2H6O2 (density 1.12g/cm^3) with water (density 1.00 g/cm^3). Estimate the freezing point of the mixture
how much heat is required to raise the temperature of 50.0 g of C6H6 at 6.00ºC to 93.0ºC
the enthalpy of vaporization of ethanol i 43.5 kj/mole at its normal boiling point of 352 k. using avalue of the molar heat capacity of liquid ethanol of 111.46 j/k/mol
Draw the corrct structure(s) for 2-chloro-2,3-dimethylpentane. Show stereochemistry clearly. Explicitly draw all four groups,
Water dissolves table salt (NaCl) because: A. NaCl is hydrophobic. B. NaCl has a polar covalent bond. C. water molecules surround the Na and Cl ions due to electric attraction.
A mass of mercury occupies .750L. What volume would an equal mass of ethanol occupy if mercury's density is 13.546 g/mL and the density of ethanol is .789 g/mL?
apply to separation of a solution containing pentanol (FM 88.15) and 2,3-dimethyl-2-butanol (FM 102.17). Pentanol is the internal standard.
suppose you chose phenolphthalein , which changes color at the end point from colorness(acidic) to pink at pH8.5 .Would you need the same , more or less volume of NaOH in the back-titration?
A buffer solution is prepared by mixing 47.5 mL of 0.772 M carbonic acid with 58.8 mL of 0.0346 M sodium hydrogen carbonate. 1. Calculate the pH (to two decimal places) of this solution. Assume the 5% approximation is valid and that the volumes are a..
calculate the volume of 0.1205 M NaOH that will neutralize 10.0 mL of 3.8% (by mass) citric acid solution.Assume the density
