Assume water boils at 100.0 C in Houston(near sea level) and at 90.0 C in Cripple Creek Colorado(near 9, 500 feet). If it takes 4.7 min to cook an egg in Cripple Creek and 4.4 min in Houston, what is Ea for this process? Enter your answer in scientific notation.
What is the pH of a 0.15 M solution of aqueous Acetic Acid. The Ka of acetic acid is equal to 1.7 x 10^-5
The liberated hydrogen occupied a volume of 320ml when collected over water at 25 degrees celcius and the pressure of the gas was equalized to the atmospheric pressure of 750mm as in this lab. Calculate the equivalent weight of the metal, M.
The comple IrCl(PMe3)3 is square planar with iridium having coordination number 4. When this complex reacts with Cl2 , two six coordinate complexes are formed. P NMR suggest one P environment in one of these products and two P environments in the o..
water consistent with this oversimplified approach? Explain your answer ( note that there is a threshold temperature below which this approach will have a significant error)
When power was turned off to a 30.0 gal. water heater, the temperature of the water dropped from 75.0°C to 22.5°C. How much heat was lost to the surroundings? (1 gal = 3.785 L) Assume the density of water is 1.00 g/mL.
calculate the freezing point of this solution, boiling point of this solution, the vapor pressure change (from 23.76 torr at 25C) for the solution, the osmotic pressure of the solution, and the height of a column of water corresponding to this osm..
Calculate the pH at the second stoichiometric point when 100 mL of a 0.020 M solution of sulphurous acid (Ka1=1.4*10-2, Ka2=6.3*10-8) is titrated with 1.5 M NaOH.
Important information about Chair Conformation, Circle the least stable conformation as well.
22.87 mL of a 0.1075 M NaOH solution are required to neutralize 0.300 grams of an unknown monoprotic acid. What is the molecular mass of the acid
a box contains a mixture of small copper spheres and small lead spheres. the total volume of both metals is measured by
MgO has the same crystal structure as NaCl, face-centered cubic. How many oxide ions surround each Mg^2+ ion as nearest neighbors
If magnesium oxide smoke has been lost in too great an amount during the heating of the crucible would this have made the calculation % Mg in the product too high or too low? Explain.
