how much 0.500 M Au(NO3)3 solution would you need to prepare to accomplish this? 3) If the price of the base metal is negligible, and the price of gold is $ 1791.05/oz. ( as of the date of this publication), what is the value of the medallion?
A metal, M, can readily form the M+ cation. A nonmetal, X, is a gas at room temperature and can easily form the X- anion. Is the product of the reaction of M and X a molecule or an ionic compound?
Draw a two-dimensional conformational energy landscape (free energy on y-axis, conformational coordinate on x-axis) to show how a protein may become kinetically (not thermodynamically) ‘trapped' in a misfolded conformation.
What structure best represents the rate-determining intermediate formed when 1-methylcyclopentene reacts with Cl2.
Equilibrium between the composition of Hydrogen sulphide in the gaseous and liquid phases can be represented as Yn=48.3Xn.
