Experiment #: 6 Title: Equilibrium Reactions Purpose: To study equilibrium reactions with two experiments 1. Determine the equilibrium constant Kc and 2. Study LeChatelier’s Principle Procedure: 1. Add 10mL acetic acid and 10mL propyl alcohol in a small flask using a pipette. Mix well 2. Take 1mL pipette sample from flask and place in beaker. Add in about 25mL of water and a few drops of phenolphthalein indicator. 3. Titrate with sodium hydroxide in buret until color change. Record mL ...

Chem 219: Module 2 Exam Questions With 100% Correct Answers What are hydrocarbons? - answerMolecules composed of only the elements carbon and hydrogen What are the two major classes of hydrocarbons? - answerAromatic (benzene) and aliphatic (alkanes, alkenes, alkynes) What is the main source of hydrocarbons? - answerFossil fuels like coal, petroleum, and natural gas obtained by mining and drilling. What are Alkanes? - answerThey are saturated hydrocarbons because their skeleton is only c...

neurons - nerve cells where brain processes messages glia - support the neurons in many ways--insulating, synchronizing activity, removing waste cell body - contains nucleus dendrites - widely branching ("tree"), receive transmissions axon - single, long, thin, straight fiber, branches at tip action potential - excitation that travels along an axon at a constant strength resting potential - electrical polarization across membrane terminal bouton - presynaptic ending neurotransmitter - ...

▪ In the periodic table, element X is in group 2 and element Y is in group 5. what is the likely formula of the ionic compound of X and Y - Ans .X3Y2 ▪ which enthalpy changes are endothermic - Ans .the bond enthalpy of a C-H bond and the second electron affinity of oxygen ▪ explain why the halogens show an increased boiling point down the group (3) - Ans .- london forces increase - number of electrons increase - more energy to break intermolecular forces ▪ predict what would h...

SOPBAR - used to find degrees of unsaturation ((2C+2)-H-X+N)/2 Resonance Rules - -no breaking single bonds -do not exceed octet -keep net charge the same -try to have full octets (most stable) Resonance Patterns - 1. Lone pair e- next door to pi bond 2. Pi bond next to positive charge 3. Double bond btwn atoms of differing electronegativity (ex: carbonyl) Curved Arrows - show movement of pair of electrons *start at lone pair or double bond* Hybridization - sp3= tetrahedral, four domai...
