Reaction between NF3, F2, and SbF3 at 200 degrees C and 100 atm pressure gives the ionic compound NF4SbF6:
Nf3(g) + 2F2(g) + SbF3(g) -> NF4SbF6 (s)
Draw Lewis structure for the ions in this product.
A 1.5 L acid solution contains .35g total of HCl and HBr. The pH of the solution is 2.40. What are the masses of HCl and HBr
How many grams of water can be cooled from 37 C to 20 C by the evaporation of 45 gm of water?
An ideal gas is in a cylinder with a volume of 250.0 mL at a temperature of 25 ºC and a pressure of 700 torr. The gas is expanded to a volume of 1.0 L and the temperature increased to 500 ºC.
Suppose you live in an alternate universe where a different set of quantum numbers is required to describe the atoms in that universe. The quantum number rules in the alternative universe are
Condensation polymers are made using a monomer with two functional groups which split off as the remainder of the two monomers are joined together. Often the small molecule eliminated in the process is water
Consider a galvanic cell consisting of a magnesium electrode in contact with 1.0 M Mg(NO3)2 and a cadmium electrode in contact with 1.0 M Cd(NO3)2. Calculate Eo for the cell and draw a diagram showing the cathode, anode
If it takes 1250 J to raise the temperature of 33.5g of a substance 59 deg C what is the specific heat of the substance
The oxygen atom with its 2s orbital forms a s bond with one of the three sp2 hybrid orbitals of the carbon atom; the two hydrogen atoms with their 1s orbitals each form a s bond with one of the three sp2 hybrid orbitals of the carbon atom.
When dealing with radical halogenation, why does the most stable intermediate compound have the fastest reaction rate. I would assume that this is because the more stable intermediates are formed more readily and more permanently,
Formic acid (HCO2H, Ka=1.8X10^-4) is the principal component in the venom of stinging ants. What is the molarity of a formic acid solution if 25.00 mL of the formic acid solution requires 29.80 mL of 0.0567 M NaOH to reach the equivalence point
