The following reaction is carried out in a bomb calorimeter: 4NH3 (g) +5O2 (g)-->4NO (g)+6H2O (g)
The calorimeter constant is 45.0kJ/K. when 34.0g of NH3 are reacted in the calorimeter, the temp rises by 10 degrees C. What is the change in energy, delta E, for the rxn?
what is the spin notation for
consider a particle confined to a two-dimensional box where the length in the x dimension is a and the length in the y
Calculate the number of grooves per centimeter for your grating. Hint: if the groove spacing was 0.1 ft, then how many grooves would you have per foot?
Calculate the [H3O+], pH, and the fraction of dissociation (α) in an aqueous 0.140 M NH3 solution. (Hint: You will need the Ka, located in the back of your textbook.)
Recall from the prelab the enthalpy of vaporization of isobutane. Isobutane is the fuel used in disposable lighters. The lighters' operation is dependent upon the butane's ability to vaporize and be ignited, and this depends somewhat upon the larg..

The gas plus vapor at its equilibrium partial pressure leaves the liquid at the same temperature and pressure. If 6.550 g of acetone has evaporated, what is the vapor pressure of acetone at 25 degrees Celsius?
What polypeptide would be synthesized from the following template strand of DNA:3' CGG AGA CGG ACG 5'
Define the Beer-Lambert Relationship in detail.How does this relationship allow one to quantify an unknown?
Identify (name) each pathway, the enzyme whose activity determines how much glucose-6-P is metabolized by that pathway, one effector (regulatory molecule) which controls the activity of each enzyme, and how the effector affects the activity of the..
Apamine is a small monomeric peptide toxin present in the venom of the honeybee. it has the sequence: CNCKAPETALCARRCQQH a)it is known that apamine does NOT react with iodoacetate. how many disulfide bonds are present?
What is the molar solubility of PbI2 in water. For PbI2, Ksp=7.9x10-9. You may assume that the ions do not form ion pairs in solution.
