YOLO exam Flashcards
A(g) + e- → A- (g) + energy
electron affinity
A(g) + energy → A+(g) +e- (first ionization
ionization energy
Polarity Scale
Non polar 0-.4, polar covalent is from 0.4 to 1.7 and ionic is from 1.7 onwards
Boiling point stuff
Large electron cloud leads to large polarization which leads to large London dispersion forces and high boiling point
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.
red litmus
Used to identify bases. turns blue
blue litmus
Turns red when acidic
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
Binary ionic compounds are formed when
Metal carbonates decompose, metal and non metal, metal hydroxide decomposing`
To generate carbon dioxide gas
Decompose a metal carbonate
To generate a metal oxide
Decompose a metal carbonate or a metal hydroxide
in combustion reactions
Heat must be released, not absorbed. also, these combustion reactions are also technically synthesis reactions
Net dipole
OKAY
Arrhenius acids and bases
Release H+ and OH- when dissolved in water
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??
