The following set of solutions are prepared by dissolving the requisite amount of solute in water to obtain the desired concentrations. The pressure of the system is then manipulated such that movement is from the solution listed first to the solution listed second. Classify each set of solutions based on the movement of solvent from the first solution listed to the second solution listed as osmosis or reverse osmosis. a. 2.1 M HNO3 to 1.2M HNO3
b. 0.05M sucrose to 5M sucrose

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."
