The solubility of NH4B is 38g/100 mL of water at 20°C and 65g/100 mL at 80°C. 1. I add a certain amount of NH4Br to a vial of water at 20°C. Much of it dissolves, but there are some grains of salt left in the bottom. I have created [ Select ] . As the temperature rises, all of the remaining solid dissolves. This solution is now [ Select ] 2. I create a saturated solution of NH4Br at 80°C with 300.mL of water and then cool the mixture to 20°C slowly and the solution remains liquid. This is an example of [Select] As soon as I jolt the vial, I destabilize the solution and [ Select ] of salt precipitates out.

Cyclonite, also known as RDX (Research Department Explosive), is used to make Semtex, a plastic explosive, when mixed with PETN. Semtex was used in the bomb that brought down PanAm flight 103 over Lockerbie, Scotland in 1988 killing 270 people. RDX is typically recrystallized from acetone. 1 gram of RDX is soluble in 100 mL of cold acetone (0 0C) and in 25.0 mL of boiling acetone. A student performed recrystallization starting with using 5.0 mL of acetone. a. What is the maximum amount of crude RDX the student can purify given this volume of acetone in order to maximize the % recovery? b. A student reported 65% recovery from the process of recrystallization after using 5.0 mL of acetone and the mass that can be used with that volume (part a). Is 65% the maximum % recovery of RDX using the volume you calculated in part a? Show your work.

Which statement best describes the stereochemistry of the product?
Will the solubility of CaCO3 in water increase or decrease if the pressure of CO2 gas above the saturated solution is increased? Note that CO2 gas reacts with water to produce a weak diprotic acid H2CO3. This acid can undergo the loss of one or two protons to form HCO3- and CO32- ions (these are bicarbonate and carbonate).
