Derive the expression for the energy of a molecule.
Consider the system of a gas adsorbed onto a surface. The gas can be treated as a two-dimensional ideal gas, and modeled as a particle in a two-dimensional box. Derive the expression for Q and derive an expression for the energy of this molecule.
A solution is prepared from 0.95 grams of H3PO4 ,(Phosphoric acid) and 1.15 grams of HClO4 (perchloric acid) in 150 mili litres of solution then determine how many milliliters of 0.425 M sodium hydroxide( NaOH) is needed.
if potassium bromide of 25.5 grams is dissolved in enough H 2 O to make 1750 mL of solution, determine the molarity of the solution?
how many grams of Na2CO3 (FM 105.99) should be mixed with 5.00 g of NaHCO3 (FM 84.01) to produce 100ml of buffer with pH 10.00.
consider a major oil spill in a lake ( a prototype situation related to Alaska Oil Spill few years ago and many subsequent spills) Amount of oil spilled is 2.9 mega gram (Mg).
