Here is answers to [[2018-2019 Review HW for Naming Molecular Compouds Lewis Dot Structure Percent Composition and Two Step Mole Calculations]].<br> <br> Part I<br> 1. Metals, cations<br> 2. Molecules<br> 3. After boding, all elements want 8 valence electron around them except H (2e<sup>-</sup>), Be (4e<sup>-</sup>), B (6e<sup>-</sup>) and 3rd energy level and greater elements can exceed 8.<br> 4a. share, a covalent bond, molecular, ΔEN < 1.7<br> 4bi. cation 4bii. sea of free flowing valence electrons<br> 5.Ions (a cation and anion).<br> <br> Part II<br> a. C is central atom and 0 LP, 4 single bonds<br> b. P is central atom and 1 LP, 3 single bonds<br> c. N is central atom and 0 LP, 2 single bonds and 1 double bond (3 Resonance structures)<br> d. Se is central atom and 0 LP, 6 single bonds (Se can exceed octet rule)<br> <br> Part III<br> a. Tetrasulfur nonachloride<br> b. S<sub>1</sub>O<sub>3</sub><br> c. Nitrogen dioxide<br> d. F<sub>5</sub>Cl<sub>1</sub><br> <br> Part IV<br> a. 75.1g Cl<sub>2</sub> @<nowiki>STP</nowiki><br> b. 8.19E23 molecules H<sub>2</sub>O<br> c. 6.51E22 f.u. Al<sub>1</sub>Cl<sub>3</sub><br> d. 130L (or 1.3E2L) N<sub>2</sub> @<nowiki>STP</nowiki><br> e. 34.9g of solid (did not give chemical formula because you need to determine it for problem) <br> f.
