How would a decrease in the volume of a gas initially heldat STP affect. The Kinetic energy of the gas if T is constant, the average speed of the gas and the total number of collision with the walls of the vessel?
the frost melts due to the sun heating the surface of the car above the melting point B) the frost evaporates due to the sun heating the solid c) the frost cycles as does the saturation level of moisture in the winter air does from night to day Th..
A certain first-order reaction (A->product) has a rate constant of 7.50×10-3 at 45 . How many minutes does it take for the concentration of the reactant, , to drop to 6.25 of the original concentration?
Explain why most of the difference in omega-3 PUFAs in Alaskan salmon are seen in the phospholipid component of the fish rather than in the triglyceride component of the fish
Benzyl alcohol was selected by a student to crystallize fluorenol because the solubility characteristics of this solvent are appropriate. however, this solvent is not a good choice. Explain
What was the applied pressure at the end of this process if the final concentrations of the solutions were 0.053 M and 0.150 M at a temperature of 23 degrees C
Calculate the equilibrium constant at 24 K for a reaction with ?Ho = 10 kJ and ?So = (-100) J/K. (Don't round unil the end. Using the exponent enlarges any round-off error.)
Which of the following terms define(s) an acid according to the Bronsted-Lowry theory?
