Arrange the liquids pentane (CH3CH2CH2CH2CH3CH3CH2CH2CH2CH3), pentanol (CH3CH2CH2CH2CH2OHCH3CH2CH2CH2CH2OH), and pentanal (CH3CH

2CH2CH2CHOCH3CH2CH2CH2CHO) in order of decreasing viscosity, surface tension, and boiling point.To rank items as equivalent, overlap them.

Answer: pentanol>pentanal>pentane

Explanation:

Pentanol will have the highest viscosity, boiling point and surface tension because it has the highest degree of intermolecular interaction. The molecules of pentanol are held together by strong intermolecular hydrogen bonds which raises its boiling point. This degree of intermolecular interaction is absent in pentanal and pentane. They have much lower boiling points with pentane having the lowest boiling point due to the presence of weak London forces.

Calculate the pH and pOH of 0.010 mol OH- per liter
Sati [7]
We can use a variety of formulas to determine our answers here.

Our formula for pOH is -log(mol), and we can plug it in as -log(0.010). Take note that OH- is a base, not an acid. 

So, the pOH of OH- is 2.

To find pH we can set up this simple equation:
pH + pOH = 14
All we need to do is subtract 2 from 14, therefore the pH is 12.

This makes sense since acids range in the pH of 1-6, and we are dealing with a base. Hope I could help!

A hypothetical element, E, has two stable isotopes. One isotope has a natural abundance of 68.037% and has an atomic mass of 46.
I am Lyosha [343]
  • If the abundance of the first isotope is 68.037%, then the abundance of the second isotope is 100%-68.037%.

Substituting into the atomic mass formula,

47.574=(46.449)(0.68037)+x(1-0.68037)\\\\ 47.574=31.60250613+0.31963x\\\\15.97149387=0.31963x\\\\x \approx \boxed{49.969 \text{ u}}

At STP, fluorine is a gas and iodine is a solid. This observation can be explained by the fact that fluorine has
motikmotik
<span>The answer is 4. The molecules of each material entice each other over dispersion (London) intermolecular forces. Whether a substance is a solid, liquid, or gas hinge on the stability between the kinetic energies of the molecules and their intermolecular magnetisms. In fluorine, the electrons are firmly apprehended to the nuclei. The electrons have slight accidental to stroll to one side of the molecule, so the London dispersion powers are comparatively weak. As we go from fluorine to iodine, the electrons are far from the nuclei so the electron exhausts can more effortlessly misrepresent. The London dispersion forces developed to be increasingly stronger.</span>
