Explain why some substances are soluble in water and some are not. Respond to the statement "like dissolves like". Give specific examples. Some ideas for responses: Discuss solubility in other solvents (besides water)
What is an electrolyte? What determines if it is a strong or weak conductor? How does this relate to solubility? Give some specific examples.
What is the Hydrolysis equation for NaHSO4 and how do you calculate the Ka and Kb without looking it up with a pH of 0.81. Would solid benzoic acid dissolve in a solution of baking soda NaHCO3
what is the maximum kinetic energy of a photo electron ejected from cesium by 555nm light? note that if the wavelength of the light used to irradiate the cesium surface become longer than 600 nm, no photoelectrons are emitted.
Derive the rate law, and show that this reaction may follow the first-order equation at high pressures and the second-order equation at low pressures.
If potassium ion is in solution, the ion could be reduced to potassium metal. In acidic solution, which would be more thermodynamically favorable: the reduction of K+ or the reduction of H+
Balance the following redox reactions. Break your answer down into individual steps not just the final balanced numbers. a) P4(s) + NO3^- ==>> H2PO4^- +NO(g) (acidic solution)
a chemist is commissioned to produce 50000 liters of 0.550 m aqueous phosphoric acid. the chemist can purchase solid
The % ionization of a weak acid always declines in a solution that contains the salt of the anion relative to a solution of the acid alone. For example the % dissociation of the acetic acid is less in a solution that contains sodium acetate than i..
Phosphorous pentachloride forms from phosphorus trichloride and chlorine: PCl3(g)+Cl2(g)->PCl5(g) given: ?Ssys=-170.2J/K, ?Ssurr=295.0J/K, ?Stotal=124.8J/K, reaction is spontaneous under standard-state conditions at 25
In a calibration of a calorimeter, 50.0 g of water at 60.0 degrees C is added to 50.0 g of water at 20.0 degrees C to give a mixture 39 degrees C. What is the heat capacity of the calorimeter used in this experiment
At what point in a Grignard Reaction is it no longer water sensitive? explain why the reaction can be exposed to water after this point
What role do the potassium chloride (KCl) and potassium sulfate (K2SO4) play in this experiment
How much heat energy, in kilojoules, is required to convert 61.0 g of ice at -18.0 C to water at 25.0 C ?
