As demonstrated by X-ray diffraction data, the proton and Cu(I) catenates share a similar structure, although the proton is bound to a single phenanthroline moiety, and not shared equally between the four nitrogen basic sites42. Regardless, the complexation of a single proton makes each of th...
aCompare the magnitude of intermolecular forces of H2O and O2:[translate] aThe hydrogen bond is a weak bond,but than van der Waals force is strong.H2O has two hydrogen atoms.The oxygen atom has two lone pairs of electrons, which is easy to other hydrogen atoms to form hydrogen bonds, so...

The water molecule is made up of two hydrogen atoms and ane oxygen atom.They form a polarmolecule,thet is,one with a slightiy positily positive end and a slightly negative end.Because water is polar,it can break dowm both solids and gases.The nutrients in whateverfa...
Various other properties of water, such as its high specific heat, are due to these hydrogen bonds. As the temperature of water is lowered, clusters of molecules form through hydrogen bonding, with each molecule being linked to others by up to four hydrogen bonds, each oxygen atom tending to...
<p>To determine whether the density of sulfur vapor relative to oxygen can be concluded to be 2 based solely on the fact that the mass of a sulfur atom is double that of an oxygen atom, we need to consider the relationship between molecular weight and de
Why is hydrogen bonding only possible with hydrogen? a. because hydrogen is the only atom whose nucleus is not shielded by electrons when it is involved in a covalent bond b. because hydrogen is the only atom that is the same size as an oxygen atom c. bec...
. What would happen if you introduce oxygen in a vacuum full of dilithium? Will it react? If not, then there must be some kind of logic as to why it doesn't, no? Logged Corribus Chemist Sr. Member Posts: 3550 Mole Snacks: +545/-23 Gender: A lover of spectroscopy and chocolate...
