A rough sketch of the periodic table is to be drawnshowing the diagonal relationship between Li and Mg. Also, reactions of both these metals with oxygen and nitrogen and the comparison of solubilities of carbonates, fluorides, and sulfates are to be discussed. Concept Introduction: In the periodic table, elements are arranged in order of their atomic masses. Elements in the same group tend to exhibit the same chemical and physical properties. Adiagonal relationshipexists between a few pairs of diagonally adjacent elements. The major factor behind the diagonal relationship is the electron charge density around the metals. Fluorides, carbonates, phosphates, and oxalates of alkali metals (Group 1) are soluble. While those of alkaline earth metals (Group 2) are insoluble.

An open vessel containing water stands in a laboratory measuring 5.0 m x 5.0 m x 3.0 m at 25 °C ; the vapor pressure (vp) of water at this temperature is 3.2 kPa. When the system has come to equilibrium, what mass of water will be found in the air if there is no ventilation? Repeat the calculation for open vessels containing benzene (vp = 13.1 kPa) and mercury (vp = 0.23 Pa)

Every chemist knows to ‘add acid to water with constant stirring’ when diluting a concentrated acid in order to keep the solution from spewing boiling acid all over the place. Explain how this one fact is enough to prove that strong acids and water do not form ideal solutions.
