At a certain concentration of reactants the rate of appearance of water in the following reaction is 0.43 M/s. HINT: Watch the sign of the rate!
4NH3 + 7O2 4NO2 + 6H2O(A) What is the rate of reaction of O2?________ M/s(B) What is the rate of reaction of NH3?________ M/s
One of the steps in the commercial process for converting ammonia to nitric acid involves the conversion of NH3 to NO:
Treatment of the bicyclic chloride A with lithium in tetrahydrofuran (THF) gave the monocyclic product B, C9H9Li. In deuterated THF, B exhibited a single proton NMR signal at 6.72 ppm
Mehtanol-water solutions behave as essentially ideal solutions (the activity coefficients which measure deviation from ideality are equal to or close to one).
Calculate the mass of methane that must be burned to provide enough heat to convert 151.0 g of water at 43.0°C into steam at 124.0°C.
Calculate the molar solubility of thallium chloride in 0.20M NaCl at 25 degrees Celcius. Ksp for TICl is 1.7 x 10 -4. What volume of 0.500 M HNO3 is needed to titrate 60.00 mL of 0.500 M Ca(OH)2 to the equivalence point?
Osmium has a density of 22.6 g/cm3. What volume would be occupied by a 21.8 g sample of osmium?
what practical and creative decision must a scientist make? What important criteria must this choice fulfill?
Reversible adiabatic processes are isentropic. Are isentropic processes necessarily reversible and adiabatic?
The half-life of tritium (31H) is 12.3 years. If 47.0 mg of tritium is released from a nuclear power plant during the course of a mishap, what mass of the nuclide will remain after 24.6 years?What mass of the nuclide will remain after 98.4 years?
