Draw molecular-orbital (MO) diagrams for OF+ and OF-Determine the bond order of each and classify it as stable or non-stable. If stable, tell whether the species is paramagnetic or diamagnetic.
A tank of hydrogen has a volume of 22.9 L and holds 14.0 mol at 12.0 C, what is the pressure of the gas in atm
Determine the mass of precipitate (in grams) that forms when 213.8 mL of 0.132 M CaCl2 solution is reacted with excess AgNO3 solution.
What mass of solid sodium fluoride (molar mass = 41.99 g/mol) should be added to 1.0 L of 0.23M hydrofluoric acid to make a buffer with a pH of 2.94? (Ka of HF = 1.36 x 10-3)
write the molecular and net ionic equation for when AgNO3 and Na2CO3 are mixed. Then write the net ionic equation when each of the following stresses are applied to the same mixture.
analyze the societal implications of using this process
There are two key concepts to keep in mind throughout the exercises: 1) What is the unit cell for each structure? 2) What are the coordination environments of the atoms involved?
what mass of (NH4)2SO4 must be dissolved in 0.100L of 0.350M NH3 to produce a buffer solution with pH 10.05?
The excess I3- was titrated with 50.00 mL of a 0.02000 M Na2S2O3 solution. What was the mass percent of arsenic trichloride in the original sample?
At standard temperature, a gas has a volume of 371 mL. The temperature is then increased to 131C, and the pressure is held constant. What is the new volume?
Estimate the temperature you should dope at (°C) if you must have a concentration of 100 P atoms per 10 million Si atoms at a depth of 10 nm in 5 minutes.
The half life of polonium-210 is 138.4 days. How many milligrams of polonium-210 remain after 415.2 days if you start with 2.0 mg of the isotope?
Calculate the change in entropy (in J/K) when 89.8 g of nitrogen gas is heated at a constant pressure of 1.50 atm
