1) Differentiate between “cryptand” and “cryptate”. Give one example for each and draw its structure. 2) Differentiate between “crown ether” and “cryptand”. Give one example for each and draw its structure.
1. What is the key step of redox calculations? 2. What is the relationship between normality and molarity? What is the relationship between equivalent and mole? What is the relationship between formula mass and equivalent mass?
Differentiate between exothermic and endothermic reaction and give one example of each.
For each of the following processes: (i) give an example of a redox reaction, I expect chemical formulae here, it may be easier to hand write these because the nomenclature is important. (ii) give an example of a prokaryote that utilizes this process and explain why an organism uses this process (e.g. why would cyanobacteria utilize phototrophy?). (iii) describe in detail how these processes can impact the environment and provide a direct example to support your claim. Organotrophy ...
how can i compare between the three methofs of precipitation titration? a- Mohr Method b- Volhard Method c-Fajans Method
Explain each colour change or observation made throughout the iodometric titration experiment. Redox 1: 2Cu+ + 2I- --> 2Cu+ + I2 Precipitation: Cu+ + I- (excess) --> CuI (yellowish) Redox 2: I2 + 2S2O3 2- --> S2O3 2- + 2I- Redox 1 + 2: 2Cu2+ + 2S2O3 2- + 2Cu+ + S2O3 2- My observation: bluish to yellowish - addition of KI to copper (II) sulfate solution results in a formation of CuI solution (Precipitation)? yellowish - brownish/dark blue -...
An Acid-Base Titration Lab Define Lewis acids and bases. Give an example of each. Based on the Brønsted-Lowry theory of acids and bases, complete the equations for the following acid-base reactions. In your answer be sure to indicate each conjugate acid-base pair: HNO3 + OH- à CH3NH2 + H2O à OH- + HPO4-2 à When discussing the theories of acids and bases, the Arrhenius, Brønsted-Lowry, and Lewis theories will each describe compounds in their own unique and different way. Based...
