If the Ksp for aluminum hydroxide is 1.9 X 10^(-33), calculate the solubility (in mol/liter) of Al(OH)3 in a solution of .1 M NaOH
For many compounds, it is possible to draw multiple Lewis dot structures that are simplifications of the structure of the true molecule. The actual structure of the molecule
A solution is prepared by dissolving 396 g of sucrose (C12H22O11) in 624 g of water. What is the vapor pressure of this solution at 30°C? (The vapor pressure of water is 31.8 mmHg at 30°C.)
It takes 254kj/mol to eject electron for a certain metal surface. What is the longest wavelength of light that can be used to eject electrons from the surface of this metal via the photoelectric effect.
if 0.200mole of NaOH is added to 1 liter of solution that is 0.100M in aqueous ammonia and 0.200M in ammonium chloride how much does the Ph change.
The atomic weight of a newly discovered el- ement is 110.352 amu. It has two naturally occuring isotopes. One has a mass of 111.624 amu.
Compare this temperature with the true boiling point of N2. The boiling temperature is the temperature at which the areas under the two van der Waals loops are equal. In order to solve the problem
an activation energy of 43.6 kJ/mol, what will be the rate constant for this reaction at 75oC?
Draw the accepted mechanism for each reaction and illustrate how each stereoisomer is formed in the reaction.
Assume that a particular reaction evolves 245kJ of heat and that 24kJ of work is gained by the system what is the delta H inside and the surroundings
Suppose that 1.06 g of rubbing alcohol (C3H8O) evaporates from a 64.0-g aluminum block. If the aluminum block is initially at 38°C, what is the final temperature of the block
Using the equation Fe2O3+2Al-->2Fe+Al2O3, how many grams of Al are needed to completely react with 135 g Fe2O3
