ΔG values are used to predict the direction in which a reaction will proceed. Reactions proceeed in a manner that minimizes: A. free energy B. entropy C. reaction rate D. unfavorable mechanisms
A!!!Reaction directionality can be predicted from the free energy content of the products and the free e nergy contents of the reactants: ΔG' = ΔG' products- ΔG' reactants. When ΔG' is negative, the products contain less free energy than the reactants and the reaction will proceed spontaneously under standard conditions. Whe n ΔG' is positive, the products contain more free energy than the reactants and the reaction will tend to go in the reverse direction under standard conditions. This implies that reaction directionality is accomplished via minimizing free energy (i.e., free energy is negative). Answer B is false because minimizing entropy is NOT energetically favorable; entropy increases are favorable. Answer C is false because it is a kinetic property and is independent of free energy, a thermodynamic property (i.e., very slow reactions can be either spontaneous or non-spontaneous, as can very fast reactons). Answer D is false because maximizing unfavorable mechanism would increase ove ra ll fre e e ne rgy, m a k ing ΔG po sitive .

Human ear anatomy
so heres the functions: The ext. aud. canal funnels sound waves into the ear and cause the tympanic membrane to vibrate. The three ossicles (malleus, incus, and stapes) move because of the vibration of the tympanic membrane. The stapes actually presses into the oval window of the cochlea. Inner hair cells along the basilar membrane of the fluid-filled cochlea are distended as a result, and this is transduced into neural impulses that travel to the brain for processing.
STORY TIME!!!! yupii, digestion story
so you eat a burger 1st mouth breaks it up & mixes w/ saliva with α-amylase enzyme which begins carbs digestion & lubrication for easy swallowing. 2nd pharnx ensures bolus goes to esophagus or larynx thats all it does (no digestion or addition) 3rd epiglottis(cartilage) folds over the larynx to prevent food from going down the wind pipe. 4th esophagus uses peristalsis(smooth muscle contration) to push down bolus to stomach (NO digestion or addition). 5th bolus passes cardiac sphincter into stomach where physical dig. continous. In stomach, chief cells secrete pepsinogen → pepsin due to acidic pH=2. Parietal secrete HCL → pH=2. THou acidic, stomach protects itself from it w/ mucus coating. Pepsin catalyzes the hydrolysis of proteins. Then chyme(1/2digested) passesthe pyloric sphincter and into upper part of small int. a.ka duodenum The common bile & pancreatic duct both dump into the duodenum. so duodenum receives bile from the liver/gallbladder & bicarbonate & 6 digestive enzymes from pancreas 1. trypsin (protein), 2. chymotrypsin (protein) 3. pancreatic amylase (carbohydrates) 4. lipase (fats) 5. ribonuclease (RNA) 6. deoxyribonuclease (DNA) bicarbonate pH2 → 6 necessary for 6 enzyme to function. chyme moves to jejunum then ileium. duodenum - digestion, jejunum/ileium - absoprtion of food NOT water SI has villi which ↑ surface area for absoption Each villi have microvilli, villi have blood vessel & single lymph vessel a.k.a lacteal. Fats enter lacteal while carbs/proteins enter blood vessel ileum → large intestine (ABSORBS water & vitamins. LI a.k.a colon has ascending, transverse, & descending, sigmoid colon. .

D; Answer A & Bis false because beads don't change BP. The beads only provide extra surface area for condensation to occur and do not react. The component of the mixture with the lower boiling point will be well above its boiling point and thus will not condense. The vapor, however, will still contain a few of molecules of the component with the lower boiling point . These will easily condense on the beads and fall back into the flask; this is exact ly what answer D says.

How does mass spectrometry work?
the species is first bombarded with energy breaking it into charged, ionized fragments. It is then accelerated down a curved tube through a magnetic field. Each fragment has a different mass to charge ration and is thus accelerated by the magnetic field to a different degree. At a given field strength, only one or very few fragments will hit the detector. The field strength must be varied to make sure each species hits the detector The external magnetic field is increased from very low to very high
