If 150 ml of Al(OH)3 of unknown concentration with a methyl red indicator present is titrated with [0.535 M] HCl, the yellow solution turns red after 32.8 ml of the HCl is added. What is the molarity of the Al(OH)3 solution
Calculate the uncertainty in the distance of the electron (in Angstroms) at any point during its 25 Angstrom journey. (HINT: remember velocity = distance/ time)
Suppose that you first titrated 25.0 mL of 0.500 M HCL with 0.500M NaOH and then 25.0 mL of 0.500 M of a weark acid HA with 0.500M NaOH. How would the titration curves compare at 10 or 15 ml of NaOH beyond the equivalence points? Explain.
a sample of helium gas initially at 37 degrees celsius, 785 torr and 2.00L was heated to 58.0 degrees celcius while the volume expanded to 3.24L. What is the final pressure in atm.

9.780 grams of gaseous mixture contains ethane ,C2H6 and propane ,C3H8. it needs 1.120mol of oxygen when complete combustion to form CO2 and H2O. Compute the mass percent of C2H6 in the original mixture.
An electron in the ground-state He+ ion undergoes a transition to a state described by the wavefunction R4,1(r)Y1,1(?,). (a) Describe the transition using term symbols. (b) Compute the wavelength, frequency, and wavenumber of the transition.
A student standardizes his NaOH titrant solution with KHP. He performs three titrations - in each trial, the mass of KHP (204.22 g/mol) used is 1.500 g. The average amount of NaOH used in the standardization is 29.3 mL +/- 0.06 mL.
