In the old definition of standard state, STP corresponded to conditions of "standard" temperature (T=0°C) and standard pressure (p= 1 atm). At STP, 1 L of Br2 reacts totally with 3 L of F2 to form 2 L of a product. What is the formula of the product?
Arrange the members of the following set of elements in order of increasing first ionization energies. (Use the drop down lists to indicate your choice, with 1 as the smallest IE and 6 as the largest IE.)
Determine de yield or recovery percent in the synthesis of an adduct made with 0.10 mL of furan and 0.20g of maleic anhydride.
Calculate the concentration of Hg2+, HgCl+, and HgCl2 that result when 1.00 L of a 0.100M Hg(NO3)2 solution is mixed with an equal volume of 0.100M HgCl2 solution.
When you go on the protein databank and look at the Ramachandran plot, it gives you 4 plots (general case, glycine, proline, and pre-proline).
