Step-by-Step Solution:
Step 1 of 3

CHEM1041 General Chemistry 2 Notes for Week of January 25 Photovoltaic Cells Made of semiconductors like silicon General operation is as follows 1. Light his the semiconductor surface 2. Semiconductor absorbs light 3. Electrons are knocked loose 4. Loose electrons lead to flow of electrons, or electricity The flow of electrons is made possible by having two varieties of silicon N-type silicon – Made by doping silicon with phosphorus, possesses an abundance of electrons P-type silicon – Made through gallium doping, possesses a deficit of electrons Chapter 13 Solution chemistry Solute dissolves in Solvent to make Solution Solubility – Max amount of solute that dissolves in a fixed quantity of solvent at a given temperature Intermolecular Forces in solubility “Like Dissolves Like” Solutes will dissolve more readily in solvents with similar IMFs This also applies to polarity, so polar dissolves polar and nonpolar dissolves nonpolar Dual Polarity and Effects on Solubility Alcohols are organic compounds that have dual polarity due to their terminal OH group The OH group is polar The hydrocarbon chain is nonpolar This causes alcohols to be soluble in both polar and nonpolar solvents. The longer the chain, the more soluble the alcohol is in nonpolar solvents but the less soluble it is in polar solvents. Why Substances Dissolve Entropy is the main reason that substances dissolve Entropy is related to the freedom of the particles in a system Entropy is higher among solut
