In general, ionization energies increase across a period from left to right. Explain why the second ionization energy of Cr is higher, not lower, than that of Mn.
Determine the structure of compound U. Be sure to include a concise discussion of the reasoning. Construct tables summarizing the IR and 1H NMR data, and assign the peaks in the IR and NMR spectra to the appropriate structural elements in U. Expla..
Draw a mechanism for the reaction of lauryl alcohol with chlorosulfonic acid.
What are the various uses of radioactivity in healthcare. What are the future trends in healthcare with respect to the use of radioactivity.
When 25.0 mL of 0.400 M H2SO4 and 50.0 mL of 0.850 M H2SO4 are mixed, what is the molarity of sulfuric acid in the final solution?
A dry-cleaning solvent (molecular weight = 146.99 g/mol) that contains C, H, and Cl is suspected to be a cancer-causing agent. When a 0.124 g sample was studied by combustion analysis, 0.223 g of CO2 and 0.0301 g of H2O formed.
The ionization energy of hydrogen is reported to be 1.31x10^6 J mol^-1 of H. (1) compute the ionization energy for a single atom of hydrogen.

Hydrochloric acid (HCl) reacts with sodium carbonate (Na2CO3), forming sodium chloride (NaCl), water (H2O), and carbon dioxide (CO2). This equation is balanced as written: 2HCl(aq)+Na2Co3(aq) --- 2NaCl(aq)+H2O(I)+CO2(g)
The radioactive decay of a certain sample produced 936 disintegrations per minute. Exactly 3.00 days later, the rate of decay was found to be 511 disintegrations per minute. Calculate the half-life, in days, for the decay of this sample.
