Why does the dehydration of beta-hydroxy ketone occur so readily to produce the alkene compared with all the unsuccessful effort to dehydrate an alcohol under basic conditions?
What will the units of the following rate constant if the rate constant is expressed in mol/L * min. Rate = k [A][B]
what mass of sucrose should be combined with 501 g of water to make a solution with an osmotic pressure of 8.85 atm at 305 K? (assume density of solution is equal to the density of the solvent).
A sample containing 2.40 moles neon gas has a volume of 8.00 L. Assume that the pressure and the temperature remain constant.What is the new volume of gas in liters when a leak allows one-half of the neon atoms to escape?
The average kinetic energy of the molecules in a gas sample depends only on the temperature, T. But given the same kinetic energies, a lighter molecule will move faster than a heavier molecule.
Sulfur dioxide gas reacts with oxygen gas to form sulfur trioxide gas. What would the products of the reaction be
A certain sample of the mineral galena weighs 12.4 and has a volume of 1.64 mL. What is the density of galena?
Aluminum reacts with excess hydrocholoric acid to form aqueous aluminum chloride and 28.7 mL of hydrogen gas over water at 27C and 751 mmHg. How many grams of aluminum reacted
The following pictures represent the progress of a reaction in which two A molecules combine to give a more complex molecule A2, 2A ? A2. What is the order of reaction with respect to A?
An ice cube of mass 9.0 is added to a cup of coffee, whose temperature is 85 and which contains 110 of liquid. Assume the specific heat capacity of the coffee is the same as that of water.
The density of air at ordinary atmospheric pressure and 25°C is 1.19 g/L. What is the mass, in kilograms, of the air in a room that measures 12.5 x 15.5 x 8 ft
Use equations to obtain expressions for the following partial derivative for a diatomic ideal gas, assuming that the temp of the system is sufficiently low that only translational and rotational motions are thermally active.
Calculate concentrations of OH- and the pH of each basic solution. Since NaOH donates on OH- ion for each NaOH molecule, the OH- concentration is equivalent to the NaOH molarity. The pOH is calculated as -log[OH-] and the pH is calculated as 14-pO..
