The isomerization of cyclopropane follows first order kinetics. The rate constant at 700 K is 6.20*10^-4 min-1, and the half life at 760 K is 29 min. Calculate the activation energy for this reaction.
Determine the pH at the equivalence (stoichiometric) point in the titration of 22.0 mL of 0.938 M HNO2 by 0.590 M LiOH. The Ka of HNO2 is 4.3 x 10-4.
Suppose you have 5.00 g of powdered magnesium metal, 1.00 L of 2.00 M potassium nitrate solution, and 1.00 L of 2.00 M silver nitrate solution. (a) Which one of the solutions will react with the magnesium powder?
determine the average separation distance between the quantum dot and an adjacent gold nanoparticle for the molecular beacon (in the absence of the target sequence).
The ionization constant Ka of benzoic acid is 6.3x10^-5. calculate th equilibrium concentrations of H+, benzote anion and benzoic acid. The initial concentration of benzoic acid is .10 M.
The piece of iron with a mass 102.9g was submerged in a graduated cylinder filled with water. The initial level of water was 20.0 ml. The density of iron is 7.86 g/ml.
For each species listed, indicate the hybrid orbital set (sp2, sp3d, etc) employed by the central atom
What is a significant obstacle when using osmometry to determine molar masses for compounds with very high molar masses? A. The osmotic pressures may be too high to measure.
Assuming that the volume of a solid or liquid was independent of the external pressure, we deduced that there was no change in the Gibbs free energy of a solid or liquid when the pressure is changed.
The Ogallala aquifer is the largest in the United States, covering 450,000 across eight states, from South Dakota to Texas. This aquifer provides 82% of the drinking water for the people who live in this region
Identify the two important classes of catalysts. Analyze the chemical reactions that take place when a biological catalyst combines with a reactant (substrate) to form an unstable intermediate.
Can anyone please tell me what effect reacting a carbonyl compound, (specifically, (CH3)2CO) with LiCCH, followed by H2O
