Flashcards in YOLO exam Deck (25):
1

A(g) + e- → A- (g) + energy

electron affinity

2

A(g) + energy → A+(g) +e- (first ionization

ionization energy

3

Polarity Scale

Non polar 0-.4, polar covalent is from 0.4 to 1.7 and ionic is from 1.7 onwards

4

Boiling point stuff

Large electron cloud leads to large polarization which leads to large London dispersion forces and high boiling point

5

Chains of molecules with non-polar components solubility

Molecules that have an –oh bond can dissolve in water and do Hydrogen bonding but if the molecular chain is longer, more likely to have LDF which makes it more soluble.

6

red litmus

Used to identify bases. turns blue

7

blue litmus

Turns red when acidic

8

When drawing VESPR diagrams

Don’t forget to draw dipoles (the plus arrow thing), baby deltas to indicate the direction of the polarity again and that open space thing to show lone pairs. please say “net dipole” always

9

Binary ionic compounds are formed when

Metal carbonates decompose, metal and non metal, metal hydroxide decomposing`

10

To generate carbon dioxide gas

Decompose a metal carbonate

11

To generate a metal oxide

Decompose a metal carbonate or a metal hydroxide

12

in combustion reactions

Heat must be released, not absorbed. also, these combustion reactions are also technically synthesis reactions

13

Net dipole

OKAY

14

Arrhenius acids and bases

Release H+ and OH- when dissolved in water

15

Bronsted and lowry acids and bases

Acids donate protons (H+) to another substance while bases accept a proton. this theory has hydronium and water as a base. conjugate acids and bases are here too. any negative ion is a bronzed base??

16

pH

-log[H+]

17

pOH

-log[OH-]

18

[H+] times [OH-]

1.0 times 10^ negative 14

19

[H+]

Antilog(-pH)

20

[OH-]

Antilog(-pOH-)

21

strong acids and bases

dissociate (ionize) completely while weak acids and bases don't

22

in acidic solutions

concentration of hydronium is more than oh-

23

problem with Arrhenius

useful for neutralization reactions but not for H+ can't exist alone, water is polar so there must be an interaction can't explain ammonia. reactions in non-polar solvents don't follow this theory, only solvent of water

24

bronzed is good

any negative ion can be a base, acid base reaction is just transfer of proton and can occur in any substance, not just water

25

in acid base reactions

moles of Hydrogen equal moles of OH
