What do the polarity and shape of water molecules have to do with their ability to form hydrogen bonds?Hydrogen BondingThis is an attractive interaction between a hydrogen atom from a molecule or a molecular fragment X-H in which...
Hello, I understand that water has intermolecular forces such as hydrogen bonding, so it's really hard to separate the molecules. And, ethanol also has hydrogen bonding, but london dispersion force as well. Why is water more polar than ethanol? is it because ethanol also has a london dispers...
Why does water, after evaporation, not turn to H+ ions? Explain the process of how water freezes by considering the polarity and hydrogen bonding. What determines a molecule's solubility or lack of solubility in water? Why are organic solvents such as benzene regarded as non-polar su...
The atoms share electrons, but they don’t share those electrons evenly -- the oxygen ends of a CO2 molecule have a slight negative charge. Water molecules are attracted to these polar areas, allowing CO2 to dissolve in water. The Dissolution Process Carbon dioxide molecules must first pass th...
Despite the presence of the carbonyl group which imparts some polarity to the molecule, the overall nonpolar nature of the compound lies in the fact that it does not dissolve well in polar solvents such as water. Hydrogen Bonding of Water and Solvent Characteristics ...
The implications for a computing network where quantum processing plays a role, are enormous: hurricane models that account for every water molecule; global warming models that pinpoint next year's forest fires; pandemic models that ascertain which species of bat, when consumed and ...
a. What is the name of the pigment that captures light directly in photosynthesis? (2 points): Chlorophyll b. Why does the pigment appear green? (2 points): The pigmentation appears green due to wavelengths of light that have been reflected by the sun & disappear from the light and absorb...

Collagen: the challenge of reproducing the appropriate one 6. Cartilage-targeting therapeutic delivery: what is known and what is ne...
Explain why the the structure of a molecule/compound is important. Why does fatty acids solubility decrease in a non-polar solvent (such as benzene)? Explain why triethylamine, (CH_3CH_2)_3N, is very slightly soluble in water but readily soluble (with stirring) in 1.5 M HCl. ...
Urea is an organic chemical compound widely used in skincare thanks to two main characteristics:it’s a small, polar molecule. Meaning? It can easily penetrate the skin. Plus, its polarity makes it very similar to water, helping it to work as an effective hydrator. ...
