Why is O_2 nonpolar? Why is the molecule of Li2^2- a non-existent? Why is Mo(II)nitride = MoN3 and not Mo2N3? Why is PbO2 not Pb2O4? Explain why heats of hydrogenation cannot be used to determine the relative stability of 2-methylpent-2-ene and 3-methylpent-1-ene. ...
Why is the plasma membrane so important to operation of cells? Is a single molecule of oxygen ( O_2 ) held together by two double nonpolar covalent bonds? H2CO3(aq) + NH4OH(aq) --- (NH4)2CO3(aq) + H2O(l) When balancing the equation why there is a coefficient in front ...
Why trigonal planar is NonPolar? McCord - Trigonal Planar - 3 regions. If there are no lone pairs then the molecular geometry matches the electronic and is trigonal planar. ... POLARITY: NON-POLAR -As long as all three positions are the same, then the molecule cannot be polar due to per...
(A) CH3CH2NH2 (B) CH3CH2COCH3 (C) PH3 (D) CH3CH2CH2CH2CH3 (E) CHCl3 Is methanol an ionic, molecular nonpolar, or molecular polar compound? What intermolecular forces are present? What is the predominant intermolecular force in the liquid state of each of these co...
When aqueous NaOH is added to the aqueous salt Ba(NO3)2, will a precipitate form? Explain. Will a precipitate form from the reaction of Pb(NO3)2 and NaBr? Explain why or why not. Explain whether CaCl2 is polar, ionic, or nonpolar. Then describe and explain whether it is soluble or...
Describe the health consequences of CO poisoning. What are the possible treatments? Explain why the following compound is not aromatic. Why is carbon 14 less stable than carbon 12? Why toxicological chemistry is a significant part of environmental chemistry? Why is O_2 nonpolar? Why are active ...
A trigonal planar molecule will have unshared pair(s) of electrons on the central atom. A. 0 B. 1 C. 2 D. 3 E. 4 What is the Lewis structure for the molecule CO? What is the formal charge? It turns out that, in the CO molecule, the carbon is the negative end...
Classify the bond as ionic, polar, covalent, or nonpolar covalent, and give the reason. The NB bond in H_2NBCl_2 - polar covalent Is a bond between fluorine and chlorine more likely to be ionic or covalent? When a nonmetal bonds with a nonmetal: A...
The lipophilic pathway is for nonpolar solutes that can enter the leaves through diffusion, while the hydrophilic pathway is for polar solutes [54]. Accordingly, NPs or their aggregates that are smaller than 4.8 nm in diameter can easily directly enter the cuticle through the cuticular pathway. ...
