What is the effect when a system is driven in resonance? Is a particular frequency required? Explain. Would you expect to find a node or an antinode at the end of a plucked guitar string? Explain.
determine the activation energy (in kJ/mol) for the reaction. Note that the reaction is "3/2" order in CH3CHO so k has the units of 1/M1/2 s. Strategy: consider the Arrhenius equation written as a linear equation.
Would you expect a carboxylic acid group within the water-free interior of a protein to have a higher or lower Ka than it would have if it occured on the protein's surface, where it is hydrated
A closed gas system initially has pressure and temperature of 641 mm Hg and 638.0 oC with the volume unknown. If the same closed system has values of 859 mm Hg, 3.20 L and 580 K, what was the initial volume in mL?
The gas above the top liquid is at an absolute pressure of Pg. Furthermore, the densities and heights of liquid 1 and liquid 2 are P1 and P2 , and L1 and L2 , respectively. In terms of these given symbols, waht is the absolute pressure at the bott..
Calculate the change in internal energy on an isothermal compression of 1.00kg of water at 20degress from 10^2 to 10^4 kPa
If a system consists of two subsystems, one with 5 microstates and one with 10 microstates, how many microstates are in the whole system?
Substances A, B, and C can all act as oxidizing agents. In solution, a is green, B is yellow, and C is red. In the reactions in which they participate, they are reduced to A^-, B^-, and C^- ions, all of which are colorless.
