Formic acid, CH2O2, can be decomposed to produce hydrogen. The Lewis structure for formic acid, CH2O2, is show below. The atoms are labeled A, B, C, D, E. Choose the atom that has the largest partial positive charge?
Using the Boltzmann distribution given below, determine Jmax (quantum number of the most intensely populated rotational state) as a function of temperature. Then find Jmax for CN+ at 298 K and 1100 K.
Describe how branched-chain fatty acids affect the fluidity of membranes and rank the following fatty acids in the order of increasing solubility in water.
I am trying to understand the effects of leachate from landfills and its effects on groundwater, and since I am in environmental health- its effects on the human health.
Pyridine(C5H5N) is a weaker base in H2O than 2,6 lutidine (dimethylpyridine), but we observe that the pyridine-BF3 complex is more stable than the comparable lutidine-BF3. Explain the reason for this inversion in stabilities.
Using electronegativity, predict in the order of decreasing polarity the following bonds: N-P, N-O, N-C, N-S, N-F. Predict how valence electrons would pair up in the AsO4-3 ion.

How long would it take for a radioactive isotope with a half life of 2 weeks to lose at least 70% of its radioactivity? Describe two clinical uses of Radioactivity.
Which of the following compounds will produce an acidic solution when dissolved in water? What is the OH- (hydroxide ion) concentration in a solution with pOH = 2.45.
Determine How many moles of Fe 3 O 4 could be formed if 9.00 mol iron react with 12.00 mol Oxygen and determine How many grams of methane is required to form 45.5g CHcl 3 ?
Normally the alkaline earth carbonates (MCO3; M = Mg^2+, Ca^+2, Sr^+2, Ba+2) are insoluble in water. Why would the method used in this experiment work for calculating the molar mass of the alkaline earth? How would the calculations have to be cha..
