What are the important concepts and methods of sanitization and disinfection?
As gas expands from 1.00 L to 2.50 L against constant pressure of 820 torr. Calculate the change in internal energy for the gas, if 120 J of heat is transferred to the gas during the expansion.
Calculate the k value associated with the reaction at 25 degrees celcius given the Gibbs free energy of formation of N2H4 is -419.15Kj/mol
Using graphical techniques, which form of chlorendic acid (neutral, mono-anionic, or di-anionic) is not responsible for the inhibitory effect
The pressure and colume are simultaneously increased so that at every instant P and v are related by the equation, P = Av, where A is a constant.
how many mol of CO2 are produced for every mol of pentene reacted. The chemical reaction is pentene + oxygen = carbon dioxide + water.
Using a flow diagram, show the separation of a mixture containing p-bromoacetanilide, N-cyclopentyl-N-methyl-N-propylamine (N means the group is attached to the nitrogen of the amine) and m-nitrophenol. Specify the organic solvent and aqueous
Show that (∂H/∂P)T = 0 for an ideal gas using thermodynamic relationships and the definition of G
Calculate the percent ionization of phenol (HC6H5O) in solutions of each of the following concentrations (Ka = 1.3e-10.) (a) 0.181 M % (b) 0.482 M % (c) 0.733 M %
Chlorine has two isoptopes, Cl-35 as well as Cl-37 which have masses 34.96885u and 36.96490u respectively. It's average atomic mass is 35.453u. Compute the isotopic abudance of each isotope.
During the course of an experiment, 10.0 mL of water is added to 25.0 mL of aqueous 0.120 M NaCl. What is the concentration of NaCl in the resulting solution
Based on the composition and the proton nmr observations, show by the appropriate crystal field splitting diagrams what the static ground state structure must be.
A first-order reaction had a rate constant , k , of 0.0123 1/s. If the initial concentration of reactant is 1.25M , what will be the concentration of reactant after 10 minutes?
