What is the electronic configuration of Fe and Fe +2 ? Give a brief explanation.
consider an ideal gas being heated reversibly from t1 to t2 at a constant volume and then allowed to expand
Let A be the adjacency matrix of an undirected network and 1 be the column vector whose elements are all 1. In terms of these quantities, write expressions for; a) the vector k whose elements are the degrees ki of the vertices; b) the number m of edg..
A solution is prepared by dissolving 4.9g sucrose (C12H22O11) in 175G water. Compute the boiling point of this solution. Sucrose is anon electrolyte.
A 65g sample of xenon at 298.15 K is allowed to expand adiabatically from an initial pressure of 3.0 bar to a final pressure of 0.5 bar. (Cp = 20.786 J/(K mol)), Cv can be found by assuming that xenon is ideal. If this expansion is reversible, wha..
