Choose five different polymers obtained through step polymerization. Present its synthesis as well as the detail mechanism of the reaction; talk about their commercial applications or potential commercial applications if these polymers are still being developed. Illustrate mechanism clearly.
In an experiment, 0.30 mol H2 and 0.30 mol I2 are mixed into a 1.00-l container, and the reaction forms HI. If Kc =49. for this reaction, what is the equalibrium concentration of HI. I2(g) + H2(g) 2HI(g)
Explain how much can the pH change if 300 mg/L TCE (C2HCl3) is cheap completely to ethene with H2 as the electron donor. Presume a completely un-buffered system.
A solution is made by dissolving 4.055 g of FeCl3 in 500 mL of water. The freezing point of this solution is -.316 C. What is the van Hoff factor (i) for FeCl3 at this concentration? (kf for water is 1.86 C/m)
Why must we know both in order to explain the physical properties of the molecule. physical properties to be considered are solubility and the points when the molecule changes states
