Explain what is the predicted pH of a 0.100M solution of NH4OH. (Aqueous ammonia) of the ionization equations
What do these results tell us about the difference in molecular mass between the aroma molecules and the colour molecules? In the lab there were both an 80C and a 100C distillate
What is the pressure in the cell? The volume is reduced until the cell is essentially full of liquid n-butane with only a few bubbles of n-butane gas remaining. What is the pressure?
A sample of molten iron occupies of a volume of 7.11 x 10-3 L. If the density of iron is 7.86 g/cm3, what is the mass of iron in grams in the sample?
A Diels-Alder reaction of 2,5-dimethylfuran and maleic anhydride gives a compound A that undergoes acid-catalyzed(H2SO4) dehydration to give 3,6-dimethylphthalic anhydride
What is the value of the equilibrium constant at 25 degrees C for a reaction, if the value of ?G°rxn is -47.8 kJ at 25 degrees C
Water self ionizes to a small extent creating equal concentrations of hydronium and hydroxide ions. What is the molar concentration of these ions in water at 25oC.
Calculate the molar heat of neutralization (in kJ mol-1). The heat capacity of the calorimeter is 10 cal/g·0C.
briefly describe the theory behind IR spectroscopy and why it is a valuable technique to chemists.
Later the student discovered that the percent H2O2 derived from this determination was less than the percents obtained from the second and third determinations, both performed at room temperature. Briefly explain.
the volume of a typical bacterical cell is on the order of 1.0 cubic microns. at ph 7.0 how many hydrogen ions are
Determine a crystallization of sulfanilamide in which 10mL of hot95% ethyl alcohol is added to 0.10 g of impure sulfanilamide. After the solid has dissolved the solution is cooled to room temperature and then placed in an ice-water bath.
