Calculate the concentrations of all species in a 0.840 M Na2SO3 (sodium sulfite) solution. The ionization constants for sulfurous acid are Ka1 = 1.4 X10^-2 and Ka2 = 6.3 X 10^-8.
How many grams of water should be produced and What is the theoretical yield of nitrogen?
If a sample containing 2.00 mL of nitroglycerin ({rm{density}} = 1.592{rm{g/mL}}) is detonated, how many total moles of gas are produced?
odium carbonate (Na2CO3) can be produced by heating sodium bicarbonate (NaHCO3). A student heats 5.128 g sodium bicarbonate to completely decompose the sample to sodium carbonate.
A 2 mL solution containing 1.40 uCi/mL is injected into the blood stream of a patient. After dilution, a 1 mL sample is withdrawn and found to have an activity of 2.9 * 10-4uCi. Calculate the blood volume,

Values of the rate constant for the decomposition of N2O5 at four different temperatures are as follows: Determine the activation energy (I got this step right, Ea = 101.15 kJ/mole)
urea at 25c are 0.605 atm and 0.245 amt respectively. calculate the van't hoff factor for the CaCl2.
What is the weight percent concentration of sodium carbonate in your unknown if it takes 37.25 mL of 0.1018 M hydrochloric acid to reach the second equivalence point of the titration
construct an energy level diagram (molecular orbital) for the molecule SO. We are then asked to comment on the ionic species of SO - bond order, bond distance etc. So far so good.
