Answer #1

Solution:

The ration of evaporation rate between H:OH is 1:1*E5 the huge difference is due to the dissociation energy of OH is large while hydrogen is nearly negligible, the details of disscociation of water is enclosed below.

A molecule of octane contains about six times the mass of a molecule of water. Nevertheless, if one pours liquid octane onto liquid water, the octane floats on top of the water. How can this be? A salt crystal dropped into a beaker of water becomes smaller and eventually seems to disappear. However, the same salt crystal remains intact at the bottom of a beaker of octane. Explain. A beaker of water is allowed to sit underneath another, larger beaker...

Low barrier H-bonds: require the distance between heteroatoms to be larger than for a normal H-bond redistribute electron density in the reactive intermediate and accomplish rate acceleration by hydrogen tunneling require the pKas for the two heteroatoms to be different have energies of 60 kJ/mol or more because the energy barrier the H atom must surmount to exchange heteroatoms becomes greater as the distance between hetroatoms decreases

Question about mixed solvents for recrystallization. I am having a hard time conceptualizing how a mixed solvent would work in a scenario where P and O nitronitroacetanilide are recrystallized with a small amount of hot Ethanol followed by a larger volume of water. From the structure of the molecules I assumed that the Para form of nitroacetanilide is more polar than the Ortho form. Second, I know that water>ethanol for polarity. Finally, I know that water and ethanol can hydrogen...

We know that liquid form of water is denser than the solid form because of hydrogen bonds (if I'm not mistaken). Also HF has hydrogen bonds and I try to find the density of solid and liquid form of it but couldn't find the solid form density. Could you please explain the reason of this density difference if I'm wrong about thinking that H bonds cause this. Please also explain it for HF whether that density difference valid or not...

In transitions between vibrational energy levels of the diatomic molecule HBr (hydrogen bromide), photons are emitted with energy 5.1×10^−21J, twice this energy, three times this energy, etc. Because the mass of the bromine nucleus is much larger than that of the hydrogen nucleus, it is a good approximation to consider the bromine nucleus to be always at rest; you can think of the H atom as being attached by a “spring” to a wall. What is the effective spring stiffness...
