FacebookTweetPin Newman projection is a short hand way to represent a molecule looking straight down a bond connecting two carbons. Let’s take a look at a molecule below. In the picture below, imagine looking standing to the left and looking at the first carbon. You will see group A on top, group B to the…
FacebookTweetPin Nitric acid is a component of acid rain formed when gaseous nitrogen dioxide pollutant reacts with gaseous oxygen and liquid water to form aqueous nitric acid. Write a balanced chemical equation for this reaction . Solution: If the question says solid, we need to write (s) next to the compound, liquid means (l), gaseous…
FacebookTweetPin Periodic Table Trends Atomic radius = Total distance from an atom’s nucleus to the outermost orbital occupied by an electron.Atomic radius increases from right to left and down on the Periodic Table. Ionization energy = Amount of energy needed to remove an electrons from an atom. Ionization energy increases up and to the right…
FacebookTweetPin A sugar crystal contains approximately 1.8*1017 sucrose (C12H22O11) molecules. What is its mass in milligrams? Solution: To go from molecules to milligrams, we will first need to convert molecules to moles using Avogadro’s number, then convert moles to grams using Molar Mass of the molecule(C12H22O11) and finally convert grams to milligrams (1g=1000mg). LINKS General…
FacebookTweetPin Resonance structures are multiple electronic representations of the same molecule. The only difference between resonance structures is the location of electrons. A molecule is a hybrid of all of its resonance structures. What this means is that a molecule does NOT switch from one resonance form to another. Rather, it is a combination of…
FacebookTweetPin Standard reduction potentials for the half-reactions associated with the electrochemical cell shown above are given in the table below. a. Which of the following is the net ionic equation for the overall reaction that occurs as the cell operates? SOLUTION: In the cell, there are two half reactions. Oxidation(loss of electrons) is on the…
