What will be the concentration of Ca2 (aq) when Ag2SO4(s) begins to precipitate. What percentage of the Ca2 (aq) can be separated from the Ag (aq) by selective precipitation
A certain plant material is known to contain mainly trimyristin and tripalmitin in approximately equal amounts. Tripalmitin, the structure of which you should look up in a reference source,
Consider an amphoteric hydroxide, M(OH)2(s), where M is a generic metal. Estimate the solubility of M(OH)2 in a solution buffered at pH = 7.0, 10.0, 14.0
Why does it take a temperature of almost ,800 degrees C to melt NaCl, but stirring in water at room temperature will also effect a break-up of the lattice?
A solution is prepared by mixing 80.0 mL of alcohol with enough water to give 200.0 mL solution. Calculate the % v/v concentration of alcohol in the solution.
How do you determine number of rings, double bonds, or triple bonds from degrees of unsaturation. For example a substance C8H8 has 5° degrees of unsaturation, so determine the number of rings and double bonds
You react (E)-2,7-dimethyl-4-octene with bromine, collect product, and then perform a second reaction with potassium hydroxide.
