Assuming that the following structures exist, draw the structures of IF7, IF6G,IF5 and IF4G. In addition, what would be the bond hybridization in each of these compounds and would expect them to be stable
usually some inception time is involved during the preparation of the Grignard. Explain the reason behind
sample of this compound is combusted in excess oxygen and the products are 2.492 g of CO2 and 0.6495 g of H20. Determine the empirical formula of the active ingredient.
Estimate the pH, and the concentrations of all species in a 0.300 M phosphoric acid solution. pKa1: 2.16 pKa2: 7.21 pKa3: 12.32 Hint: Convert the pKa values to Ka values
The bonding in BF3 requires formation of hybrid orbitals on boron. If the molecule is oriented in the xy plane, what is the identity of the unfilled p orbital on boron.
The atomic weight of a newly discovered element is 98.225 amu. It has two naturally occuring isotopes. One isotope has a mass of 96.780 amu.
VO2 can exist in insulating or metallic form, depending on temperature and pressure.
Calorimetry is a method used to measure enthalpy, or heat, changes that occur during chemical processes. Two common calorimeters are constant-pressure calorimeters and constant-volume (or "bomb") calorimeters
The volume of a unit cell of diamond is .9454 nm^3 and the density of diamond is 3.52 g/cm^3. find the number of carbon atoms in the unit cell of diamond
If 50.0 ml of the solution prepared in 6 is reacted with an excess of sodium chloride, how many grams of silver chloride should be produced.
A 0.100 M solution of a weak acid, HX, has a pH of 2.110. What is the value of Ka for HX?
Many fish which normally line in mountain streams (where the water temperature is 0 degrees celcius) die when water in which they live warms up to 25 degrees C. How many oxygen molecules are there in 1.0 ml of water at these two temperatures?
A solution of NaOH(aq) contains 11.6 grams of NaOH in 129 mL of solution. Calculate the pH at 25C.
