Explain what mole ratio of molecular chlorine to molecular oxygen would result from the breakup of compound Cl2O7 into its constituent elements
what is the mechanism of the reaction between benzophenone with sodium borohydride and indicate what bonds are
At 212 mm Hg and 24 °C, a sample of gas occupies a volume of 125 mL. The volume is increased to 325 mL and the temperature is reduced to -5.0 °C. What is the final pressure of the gas in the flask?
Naturally occurring element X exists in three isotopic forms: X-28 (27.977 amu, 92.21% abundance), X-29 (28.976 amu, 4.70% abundance), and X-30 (29.974 amu, 3.09% abundance). Calculate the atomic weight of X.
The boiling point of a substance is defined as the temperature at which liquid and vapor coexist in equilibrium. Use the heat of vaporization (30.91kJ/mol) and the entropy of vaporization
A stock solution of lactic acid is 0.04M and a stock solution of lactate is 0.25M. Calculate the pKa of lactic acid given that at these concentrations the pH is 3.90
Explain the solubility of AgCl(s) in water at 25 C is 1.33*10^-5 mol/L and its H of solution is 65.7 kj/mol. Explain what is its solubility at 45.6 C
How many grams of solute are needed to make each of the following solutions?296.5 mL of 0.333 M barium acetate
Suppose that the atomic mass unit (amu) had been defined as one-quarter of the average mass of an atom of carbon instead of one-twelfth of the mass of an atom of carbon-12. What would the average atomic mass of aluminum be on this new scale
Which reaction of these potential acids and bases does not occur to any appreciable degree due to an unfavorable equilibrium
Reactant: ethane Product: CCC=CCC It should take 11 steps (1 thing is done 3 times and another is done twice) I think it has something to do with converting it using Alkynes and possibly sp hybridization
Their boiling points in C are: Ne -245, Ar -186, Kr -152, Xe -107. Using the periodic relationship between the noble gases, predict the boiling point of Radon.
