16. Every year, oral rehydration therapy (ORT) –the feeding of an electrolyte solution -saves the lives of countless children worldwide who become severely dehydrated as a result of diarrhea. One requirement of the solution used is that it be isotonic with human blood. An ORT solution contains 3.5 g NaCl, 1.5 g KCI, 2.9 g Na3C6H5O7 (sodium citrate), and 20.0 g C,H1206 (glucose) per liter. What is the freezing point of this solution? You may assume that the density of the solution is 1.00 g/mL and that the freezing point depression constant (Kf) for water is 1.86 °C/m. -0.59 oC -1.86 oC 0.00 oC +0.51 oC -7.44 oC

Reactive Processes

Reactive processes are the processes in which any reaction occurs. The reactions can be any combination reaction, decomposition reaction, combustion reaction, oxidation reaction, reduction reaction, neutralization reaction, displacement reaction, or double displacement reaction.
