Maleic acid is a carbon-hydrogen-oxygen compound used in dyeing and finishing fabrics and as a preservative of oils and fats.In a combustion analysis, a 1.054- sample of maleic acid yields 1.599 of and 0.327 of.
When 0.609 of maleic acid is dissolved in 25.00 of glacial acetic acid, the freezing point drops by 0.82 . Maleic acid does not ionize in glacial acetic acid, which has a freezing-point depression constant of.
In a titration experiment, a 0.4250- sample of maleic acid is dissolved in water and requires 34.03 of 0.2152 for its complete neutralization.The of 0.215 of maleic acid in 50.00 of aqueous solution is found to be 1.80.
What are the concentrations of H2SO4 and H2SO3 in a 25ml solution titrated with .1M NaOH. The first endpoint is reached after 37.89ml of NaOH are added (pH=7) and the second endpoint is reached after 43.57ml of NaOH are added (pH=9.8).
7.04 g of CuNO3 is dissolved in water to make a 0.300 M solution. What is the volume of the solution.
Pyridine(C5H5N) is a weaker base in H2O than 2,6 lutidine (dimethylpyridine), but we observe that the pyridine-BF3 complex is more stable than the comparable lutidine-BF3. Explain the reason for this inversion in stabilities.
A 10.00 ml sample of vinegar, density 1.01 g/ml was diluted to 100.00 ml volume. It waas found that 25.0 ml of the diluted vinegar required 24.15 ml of 0.0976 M NaOH to neutralize it
What are the metric and American engineering units of the diffusion constant?
the density of liquid octane, H8H18, is 0.7025g/ml. if 1.00ml of liquid octane is vaporized at 100 degrees 100'c and 725 torr, what volume does the vapor occupy?
Why is ratio the surface energy to the enthalpy of vaporization much less than one half?
The calorimeter cup had several millimeters of water in it when you added the HCl in Step 16: b.) The base solution was added to the acid solution but was not stirred while temperature measurement were not made: c.) Some of the base splashed out o..
A room with dimensions 7.00m by 8.00m by 2.50m is to be filled with pure oxygen at 22.0C and 1.00atm . The molar mass of oxygen
