The compound composition is described by chemical formula [La(C6H5NO2)3(H2O)2][Cr(NCS)6]2H2O.;EFFECT: creating the new reversible thermochromic material having an ability to decolour when heated to a temperature of 130 degrees.;1 exCHERKASOVA TAT'JANA GRIGOR'EVNA...
FRET can measure molecular closeness at angstrom distances of 10–100 Å and is highly efficient if the donor and acceptor are positioned within the Förster radius (i.e. the distance at which half the excitation energy of the donor is transferred to the acceptor, usually 3–6 nm)....
a. Solutions of (Cr(NH_3)_6)Cl_3 are yellow, but Cr(NH_3)_6^3+ does not absorb yellow light. Why? b. What color light is absorbed by Cr(NH_3)_6^3+? If a red light is passed through a dilute solutio...
3. Statement 3: Color of chromate and dichromate is orange. - Chromate Ion: The color of chromate (CrO4²⁻) is yellow. - Dichromate Ion: The color of dichromate (Cr2O7²⁻) is orange. - Conclusion: This statement is incorrect because it incorrectly states that both colors are ...
