CHM/PHYS diagnostics 1

Question 1

Lineweaver-Burk equation

Answer 1

1/V = (KM/Vmax)(1/[S]) + 1/Vmax

Question 2

How does competitive inhibition affect KM

Answer 2

it increases KM

Question 3

hydrostatic pressure equation

Answer 3

∆P = ρg∆h

change in pressure = density * gravity * change in height

Question 4

Pressure equation

Answer 4

P=F/A

Pressure = force/area

Question 5

Describe the negative resting potential of neurons

Answer 5

more positive ions outside the cell and fewer positive ions inside the cell

Question 6

Answer 6

trigonal planar

Question 7

Hybridization of tetrahedral atoms

Answer 7

sp3

Question 8

Hybridization of bent atoms

Answer 8

sp2 w/ 1 lone pair

Question 9

Hybridization of trigonal pyramidal atoms

Answer 9

sp3 w/ 1 lone pair

Answer 10

increases

Question 11

What helps determine the length of an element’s atomic radius (2 things)

Answer 11

both the # of electron shells and the # of valence electrons

Question 12

Ionization energy (increases/decreases) from ___ to ____

Answer 12

increases from left to right

Question 13

Periodic trends that increase up and to the right (2 things)

Answer 13

electronegativity and first ionization energy

Question 14

neutralization reaction

Answer 14

acid + base react to form water and new aqueous compound

Question 15

A reaction that utilizes oxygen and hydrocarbons as reactants and that produces carbon dioxide and water as products

Answer 15

Combustion

Question 16

Formula to find the maximum # of stereoisomers in a compound

Answer 16

2^n where “n” is the # of chiral carbons in the compound

Question 17

Meso compound

Answer 17

a compound that contains chiral centers but has an internal plane of symmetry

Question 18

Same molecular formula, different atomic connectivity

Answer 18

constitutional isomers
