Nickel(II) chloride hexahydrate is essentially a hydrate of NiCl2. It adopts a CdCl2-type structure, where each Ni is coordinated with six Cl, and each Cl forms coordination bonds with three Ni. In NiCl2, the Ni-Cl bonds have ionic characteristics. Yellow NiBr2 and black NiI2 also have...
Are dipole-dipole interactions weak or strong compared to ionic bonds? Predict the polarity of 6 real molecules. First, draw the molecules and any bond dipoles. Then draw any molecular dipoles. Explain your reasoning. How can you tell if a chemical bond is polar or not?
Is CCl4 polar or nonpolar? Is NiCl2 polar or nonpolar? Is PO3-3 polar or nonpolar? Is KrF4 polar or nonpolar? Is HCOOH polar or nonpolar? Is heptane polar or nonpolar? Does dinitrogen tetroxide have covalent or ionic bonds? Are hydrogen bonds polar or nonpolar? Is benzaldehyde polar or...
The addition of CuCl2 or NiCl2 had no observable effect on gel-mobility shift binding reactions (data not shown), indicating that at concentrations which increased the rate of oligomer formation (Fig. 3 B) these divalent metal cations do not appear to have any direct effect on the binding ...
We found that the C-type lectin domain of CLEC14A binds one-to-one to heparin with nanomolar affinity, and using molecular modeling and mutagenesis, we mapped its heparin-binding site. CLEC14A physically interacted with other glycosaminoglycans, including endothelial heparan sulfate and chondroitin ...
For a standard assay, uptake was initiated by adding 0.2 ml cells to 0.8 ml of N-minimal me- dium containing 100 µM NiCl2 and 0.5 µCi of 63Ni2+. For the ionic selectivity assay, various concentrations of divalent cations were included in the tracer uptake buffer. Typically, uptake...

When two or more atoms come together to form a molecule the resulting molecule can contain metallic bonds, ionic bonds, or covalent bonds. An ionic bond always produces a polar molecule with one part of the molecule having a positive charge and one having a negative charge. In covalent ...
Write the balanced molecular equation, complete ionic equation, and net ionic equation for the reaction that occurs when the aqueous solutions of chloric acid [[HClO_3(aq)] and iron(III) hydroxide are mixed. (Use the lowest possible coefficients, and incl ...
