At 50°C the vapor pressure of ethanol is 0.30 atm, acetic acid is 0.08 atm, water is 0.12 atm, and acetone is 0.84 atm.
A) Arrange these substances in order of increasing rates of evaporation.
B) Arrange these substances in order of increasing boiling point temperature.
Draw the molecule by placing atoms on the grid and connecting them with bonds. Include all lone pairs of electrons. Show the formal charges of all atoms in the correct structure of ClO4-
In the determination of the density of a cylinder of aluminum, it was necessary to measure the volume of the sample. The diameter of the cylinder was 38.2 mm and the length of the cylinder was 15.5 mm. What was the volume of the aluminum cylinder ..
Which has the larger hydration energy, AL+3 or Li+ (Both ions are about the same size)
What makes Maleic acid (isomer of but-2-enedoic acid), very soluble in water and only sparingly soluble in CCl4
Given that the density of solid sodium is 0.968 g/cm^3, estimate the atomic (metallic) radius of a Na atom. Assess the value obtained, indicating why the result is only an estimate and whether the actual radius should be larger or smaller than the..
The compound known as butylated hydroxytoluene, abbreviated as BHT, contains carbon, hyrdrogen, and oxygen. A 2.626 g sample of BHT was combusted in an oxygen rich environment to produce 7.867g of
Explain both alkene and carbocation stability as it relates to hyperconjugation. - Explain how hybridization relates to alkene stability.
In a typical mass spectrum, a smaller signal is observed at a mass 1 amu higher than the molecular ion peak. Why? A) Due to small impurities in the sample
write mechanisms for the following reactions, which are used in chemical tests and derivative preparations: (a) the reaction of butanal with 2,4 dinitrophenylhydrazine reagent.
A solution of glyceraldehyde, C3H6O3, has a density of 1.15 g/mL, and a mass percentage of 28.1% glyceraldhyde at 25 deg C. (molar mass = 90.078g/mol)
Water expands on freezing. Since water is the principle ingredient in soft drinks when the soft drink freezes it will rupture the can.
A standard NaOH solution is contaminated with Na2CO3. In the titration of 50.00 mL of .1002 M HCl solution, 32.00 and 32.50 mL of base are required to reach the methyl orange and Phenolpthalein end points,
