Add lone pairs to the central atoms as necessary to complete these Lewis structures. Don't worry about the positions of the lone pairs on the central atom. Focus on the number of lone pairs. Add formal charges as necessary to the following structure. All unshared valence electrons are shown. What is the overall charge on the species? Many free radicals combine to form molecules that do not contain any unpaired electrons. The driving force for the radical-radical combination reaction is the formation of a new electron-pair bond. Write Lewis formulas for the reactant and product species in the following chemical equation. Include nonbonding electrons. N(g) + NO(g) rightarrow NNO(g) Classify the compounds given below an acid, base, or salt. Place the compounds in the appropriate bins. Identify the solutes and solvents for the following solutions: table sugar (C12H22O11) in water, air (a solution of 78% N2, 21% O2, and various other gases) a solution of 30% ethanol and 70% water, bronze (an alloy of 95% copper and 5% tin) CO2(g) in water.
