Most lighters contain butane. When butane is burned in the presence of oxygen, the heat of combustion for this reaction is know to be -2856kJ. You place a 35.0 g water at 12.5 degrees C above a lighter and ignited the lighter. If the lighter initially weighed 10.25 g and weighed 8.806 g what would be the final phase and temperature of the H2O.
A 1.0 M Na2SO4 solution is slowly added to 10 mL of a solution that is .20 M in Ca^2+ and .30 M in Ag^+. Which compound will precipitate first: CaSO4 Ksp= 2.4 *10^-5 ,Ksp for Ag2SO4 is 1.5*10^-5. How much Na2SO4 solution must be added to initiate ..
If the absorbance of a sample of Diet Dr. Pepper is 0.215 at 214nm, what percentage of the 214nm radiation falling on the sample passes through it?
If a sample that is 1.200g in 25.0mL of heptane is cooled to 0 degrees C, what would be the percent recovery of the solid that would be collected? (M.P.=80 degrees C)
