SWS3022 Exam 3 Questions and Answers All Correct Define an acid - Answer-Any substance which increases the hydrogen ion concentration in a solution. Know the two ions considered acids in soils` - Answer-Hydrogen & Aluminum Understand how aluminum contributes to soil acidity - Answer-Aluminum has the ability to facilitate the splitting of water and react with the resulting H+. Aluminum reacts with water to bind to the hydroxide, leaving the hydrogen ion not neutralized (so lots of H+'s). ...

Calculate pH and pOH given hydrogen or hydroxide ion concentration and calculate hydrogen or hydroxide ion concentration given pH or pOH - pH= -log(H+) pOH= -log(OH-) pH= 14-pOH 10^pH= [H+] 10^pOH= [OH-] Compare and contrast the different types of carbohydrates (monosaccharides, disaccharides, polysaccharides) and the different roles they play in organisms - monosaccharides make up di and polysaccharides (glucose) disaccharides are typically used for quick energy (lactose) Polysacchari...

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.

MCAT Organic Chemistry Exam Questions and Answers Instantaneous Dipole Moment - Answer-Exists in an otherwise nonpolar molecule. Occurs because the electrons in a bond move about the orbital and at any moment may not be distributed exactly between the two bonding atoms, even when the atoms are identical. London Dispersion Forces - Answer-Occur between two instantaneous dipoles; the weakest dipole-dipole force (vs. hydrogen bonds which are the strongest dipole-dipole forces). Wolff-Kishner...
