Chemistry Mnemonic Devices Flashcards

Front

Pacific - Atlantic Rule: Significant Figures

Back

a. Decimal is "present" - Pacific side b. Decimal is "absent" - Atlantic side

Front

BARF - Bonding

Back

a. break, absorb, release, form b. (Breaking bonds absorbs energy, forming bonds releases energy)

Front

TAKE - Heat & Energy

Back

a. Temperature is Average Kinetic Energy

Front

TICS - Bonding

Back

a. Transfer Ionic Covalent Share b. Electrons are transferred from metal to nonmetal in an ionic bond, and electrons are shared between two non-metals in a covalent bond

Front

SNAP - Polarity

Back

a. Symmetrical Nonpolar Asymmetrical Polar b. Molecular polarity, NOT bond polarity

Front

END - Polarity

Back

a. ElectroNegativity Difference b. The difference in electronegativity tells you if a BOND is polar or nonpolar. c. END = 0 means the BOND is NONPOLAR. d. END > 0 means the BOND is POLAR.

Front

FAT CAT - Redox

Back

a. From Anode To Cathode b. (Electrons always flow From Anode Through the CAThode) c. The cathode gets fat (gains mass)

Front

RED CAT - Redox

Back

a. Reduction takes place at the Cathode (IN ALL ELECTROCHEMICAL CELLS)

Front

AN OX - Redox

Back

a. oxidation occurs at the anode (IN ALL ELECTROCHEMICAL CELLS)

Front

LEO says GER - Redox

Back

a. Lose Electrons Oxidation, Gain Electrons Reduction
