Draw the lewis structure of BeF2. I think its suppose to be an incomplete octet but why becuaseif you place two double bonds Be is complete.
Copper (II) Iodate precipitates from iodate solution. The formula of the precipitate is Cu(IO3)2. A saturated solution of this substance was made in 0.01 M KlO3. The copper concentration was found to be 0.0012M
Compression and Cooling of Nitrogen Gas. A volume of 65.0 ft^3 of N2 gas at 90°F and 29.0 psig is compressed to 75 psig and cooled to 65°F.
The standard change in Gibbs free energy is deltaG= -32.8kJ/mol. What is deltaG for this reaction at 298K when the partial pressures are PNO= .200atm, PO2= .100atm, and PNO3= .850atm
A certain sample of gas has a volume of 20.00 dm3 at 0°C and 1.000 atm. A plot of the experimental data of its volume against the Celsius temperature, ?, at constant p, gives a straight line of slope 0.0741 dm3 (°C)?1.
A sample of nitrogen gas is contained in a piston with a freely moving cylinder. At0?C, the volume of the gas is 248 mL. To what temperature must the gas be heated to occupy a volume of 479mL.
Determine an apparent radius of the tungsten (VI) ion assuming the oxide ion radius is 1.40A. Suggest a reason that the calculation might give a result that has no physical significance.
For each of the reactions, calculate the mass (in grams) of the product formed when 3.51g of the underlined reactant completely reacts. Assume that there is more than enough of the other reactant.
The wave function for the ground state of the quantum harmonic oscillator
A zero-order reaction has a constant rate of 2.90×10-4 M/rm s. If after 65.0 seconds the concentration has dropped to 9.00×10-2 M, what was the initial concentration.
