Determine if the compound is ionic or covalent. The ionic compounds are typically composed of metals and nonmetals. The metals, with the exception of hydrogen, are located to the left of the periodic table, and the nonmetals are located on the right side. An example of an ionic compound i...
How do you distinguish R and S configuration from a chiral center? Chiral centre: Chiral centre or chiral carbon can be defined as that carbon centre which is connected to four different moieties or groups so that the molecule's mirror image is non-superimposable on itself. The property of...
7. How To Determine The Acidity Of Compounds That Aren’t on the pKachart One of the keys to using a pKatable is to start byidentifying the key functional group(s) present andbe familiar with their acidities. Two of the molecules below might look a little scary because they are so hug...
How To Determine Partial Charges Last timewe talked about how electrons are the “currency” of chemistry and every reaction is a transaction of electrons between atoms. That means that if we really want to understand a reaction, we have to understand where the electrons are (and aren’t). ...
Determine which set(s) correctly represents a buffer system. Explain your reasoning. 1. H F and K F 2. H C l and N a O H 3. H C 2 H 3 O 2 and N a C 2 H 3 O 2 List three ways that pH can be measured in the laboratory and briefly describe how each method works. W...
Consider the following graphs and determine the heat of the reaction and activation energy for reactions A and B. Calculate the standard free-energy change for the following reaction at 25 degrees C. 2Au^{3+}(aq) + 3Ni(s) to 2Au(s) + 3Ni^{2+}(aq). Calculate t...
How To Use Electronegativity To Determine Electron Density (and why NOT to trust formal charge) How to apply electronegativity and resonance to understand reactivity Maybe they should call them, “Formal Wins” ? Common Mistakes: Formal Charges Can Mislead ...
