Heart Failure Exacerbation correct answers -Some of the common symptoms of heart failure include dyspnea on exertion, paroxysmal nocturnal dyspnea, orthopnea, peripheral edema and non-specific abdominal symptoms like nausea and vomiting. -Common physical findings in heart failure exacerbation include peripheral edema, pulmonary crackles, elevated jugular venous pressure, hepatojugular reflex, displaced apical impulse, and S3 gallop. Prevention of HF exacerabtion correct answers MONITOR SODI...

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...

DAT Organic Chemistry Study Review Practice Test. Enantiomer - CORRECT ANSWER Non-superposable mirror images Diastereomer - CORRECT ANSWER Non-mirror images with same chemical formula Meso Compound - CORRECT ANSWER Achiral but has stereocenters Why are axial conformations of large substituents less stable than equatorial conformations? - CORRECT ANSWER 1, 3 diaxial interactions What rings have more ring strain? - CORRECT ANSWER Smaller rings, but not cyclohexane General formu...

Four elements that make up living things: correct answers 1. Carbon - all known life things are carbon based (comes from air through plants) 2. Oxygen - (comes from air) a lot of carbon and oxy w in our biomolecules. 3. Hydrogen - (comes from water) 4. Nitrogen - (nitrogen in plants which extract it from soil) Who do we thank for Nitrogen correct answers Fritz Haber 3 common wide array complex molecules: correct answers 1. Amino acids 2. Sugars 3. Nucleotides What's the next best ...

Chem 219 Unit 3 Exam Questions With 100% Correct Answers Stereochemistry the study of the three-dimensional structure of molecules Stereoisomers Compounds with the same structural formula and connectivity but with a different 3D arrangement of the atoms in space. Enantiomers Stereoisomers that that are non-superimposable mirror images. Enantiomers have the same connectivity but different orientations (twist) of the four atoms or groups in 3D space. The two different forms of the chira...

Chapter 1 Carbon and Its Compounds CHECKPOINT PROBLEMS Practice Problem 1.1 a) S — 1s2 2s2 2p6 3s2 3p4 b) Cl — 1s2 2s2 2p6 3s2 3p5 c) Na+ — 1s2 2s2 2p6 1-2 Copyright © 2018 Nelson Education Limited Practice Problem 1.2 a) Count valence electrons. Build a basic bonding framework and account for electrons used. Add remaining electrons and check for formal charges. The molecule has a lone pair on the nitrogen. All other electrons are bonding electrons. b) Count valence electrons. Build a bas...

Chem 219: Module 2 Exam with 100% Correct Solutions What are hydrocarbons? - Answer -Molecules composed of only the elements carbon and hydrogen What are the two major classes of hydrocarbons? - Answer -Aromatic (benzene) and aliphatic (alkanes, alkenes, alkynes) What is the main source of hydrocarbons? - Answer -Fossil fuels like coal, petroleum, and natural gas obtained by mining and drilling. What are Alkanes? - Answer -They are saturated hydrocarbons because their skeleton is only comp...

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...

Chem&219 Unit 2 NAMING Exam Questions With 100% Correct Answers 2024 What does the prefix and suffix of the alkanes indicate? - answerThe prefix of the name (meth-, eth-, prop-, but-) describes the number of carbon atoms present, while the suffix - ane, denotes a saturated hydrocarbon. nomenclature - answerThe "naming" of a molecular structure, that is more systematic than simply basing the name on the number of carbon atoms present. International Union of Pure and Applied Chemistry (IU...
