In a separate experiment, it was found that, for fixed temperature and pressure, a 0.100 L sample of this compound takes 1.73 times longer to effuse than does a 0.100 L sample of Ar(g). What is the molecular formula of the compound? , draw possibl..
Indicate the number of unpaired electrons for following: [noble gas]ns^2(n-2)f^6 ? Please include the rationale?
A refrigeration tank holding 5.00 L of Freon gas (C2Cl2F4) at 25°C and 3.00 atm pressure developed a leak. When the leak was discovered and repaired, the tank had lost 76.0 g of the gas.

Image text transcribed for accessibility: A buffer was prepared by dissolving 0.370 mol of the weak acid HA (Ka = 1.00 times 10-5) plus 0.036 mol of its conjugate base Na+A- in 1.00 L. Find the pH.
The solubility of radium oxalate RaC2O4 in warm water is 0.0174 mols/Liter. Calculate Ksp for this compound. Radium is a 2nd column element somewhere below calcium.
Describe the differences in the shapes of the electron density distributions for NH3, NCl3, and PF3. Explain how the energy minimized bond angles
Predict the predominant alkene product that would form when 2-bromo-2methylpentane is treated with soldium methoxide in methanol.
The discovery of hafnium, element number 72, provided a controversial episode in chemistry. G. Urbain, a French chemist, claimed in 1911 to have isolated an element number 72 from a sample of rare earth (elements 58-71) compounds. However, Niels B..
