Nitroglycerin contains 60% as many carbon atoms as hydrogenatoms, three times as many oxygen atoms as nitrogen atoms, and the same number of of carbon and nitrogen atoms. The number of moles of nitroglycerin in 1.00 g is 0.00441. What is the molecular formula OF NITROGLYCERIN? Show work?
The Rice-Herzfeld mechanism for the thermal decomposition of acetaldehyde (CH3CO) is the following below (10 points) (1) CH3CHO ---> CH3' + CHO' (k1) (2) CH3' + CH3CHO ---> CH4 + CH2CHO' (k2) (3) CH2CHO' --->CO + CH3' (k3) (4) CH3' + CH3' --->C2H6..

The half-life of 137Ce is 30. years. If we have 150.000 g of 137Ce now, how many grams of Ce will remain in 150. years?
Calculate the molar solubility of AgBr in 4.0 M NH3. Kf for Ag(NH3)2 is 1.7 x 10^7 and Ksp for AgBr is 5.0x10^-13 5. What is the pH at the equivilaence point when 45 mL of 0.125 M acetic aced is titrated with 0.225 M NaOH? Ka for acetic acid is 1.7..
Consider a colloidal suspension(like a solution) of very small particles in a solvent. We may think of this as an ideal gas of particles in the external field due to gravity.
When Lewis and Clark came through this area in the early 1800s they were forced to portage around the "Great Falls of the Missouri".
