Why is UV light considered a mutagen? How has organic chemistry changed the world? Why are acids considered corrosive? Why is water considered a polar molecule? Why is it important to have a biological classification system? Explore our homework questions and answers library ...
Why do we say that a molecule of water is polar? What is the difference between ionic bonding and a redox reaction? Explain the relationship between the reactivity of an element and the likelihood of its existence as an uncombined element. ...
Is oh a polar covalent bond? A molecule which has one or more polar covalent bonds may have a dipole moment as a result of the accumulated bond dipoles. In the case of water, we know that theO-H covalent bond is polar, due to the different electronegativities of hydrogen and oxygen. ...
In those days, it was hard to find running water and shops where to buy things. As time went by, most pioneers had to make their homes near a river so that they could get water easily.Back in the pioneer days, people grew their own food, caught their own fish, and collected their ...
Hence floats on water. Vapors are heavier than air. Polarity of Pentane The difference in electronegativity and electron sharing between two atoms in a covalent bond determines whether the molecule is polar or non-polar. When the sharing of electrons between two atoms is unequal, the ...
2. Water Structure: - Water (H2O) is a polar molecule with a bent shape, which allows it to form hydrogen bonds due to the presence of a highly electronegative oxygen atom bonded to hydrogen atoms. 3. Hydrogen Bonding: - One of the primary reasons for the immiscibility of ether in wate...
What are the advantages and disadvantages of using sodium carbonate to soften water? Why is NaCl described as a strong electrolyte? Why do non-polar substances not dissolve in water? Explain why calcium sulfate is less soluble in sodium sulfate solution than in pure water. Why is wa...
DNA, which stands for deoxyribonucleic acid, is a nucleic acid. DNA is a polymer and contains the genetic material for humans and nearly all other living organisms.Answer and Explanation: DNA is a polymer because it is a bio-molecule that is made up of monomers. The monomers DNA is made ...
Why is water less dense as a solid? What makes water such an attractive recrystallizing solvent, especially when done on a large industrial scale? Why do non-polar substances not dissolve in water? Why is pure water neutral? Why should the recrystallization solvent have a fairly low boiling ...
Now, a question might occur that how is ammonia polar when it has a covalent bond? To answer this, one might take the example of the bonding between a fluorine atom and a carbon atom. While ideally, the electrons should be exactly in the middle of the two bonding atoms, that is not ...
