Regents Exam Review Flashcards

Flashcards for Regents Exam Review

Bright Line Spectra

The spectrum produced when electrons fall from an excited state to ground state, releasing energy.

Intermolecular Forces

Solid or High Melting Point/Boiling Point indicates strong intermolecular forces. Gas or Lowest MP/BP indicates weak intermolecular forces.

Collision Theory

Collisions increase or decrease, Direct relationship with Temp,Conc or catalyst

Excited State

Looking up the electron configuration on the periodic table that adds up but doesn’t match the ground state electron configuration.

Electron Flow

Electron flow over the wire is from the anode to the cathode.

Heat Flow

Heat flows from high temperature to low temperature.

Empirical Formula

Reduced version of a formula. Molecular formula is the unreduced version.

Table M

Acids are left side numbers and colors, Bases are on the right side # and colors.

Acids and Bases

Acids donate H+, Bases accepts H+

Equilibrium

Rates are equal, concentrations are constant.

Isomer

Same molecular, different structural formula.

OIL RIG

Oxidation is Loss, Reduction is Gain

ANOX

Anode Oxidation

REDCAT

Reduction Cathode

BARF

At the Anode Reduction Follows.

Ideal Gas Law

No attractive forces, negligible volume, random straight line motion

Isotopes

Same protons, different neutrons.

Le Chatelier's Principle

Increase Away, Decrease You Stay, for Temp, Pressure, Concentration

Half Reaction

Electrons go on the side with the more (+) charge.

The element for all organic compounds

Carbon

Nature Changes

Systems of Nature undergo changes towards Lower Energy, Higher Entropy (Randomness)

Average Kinetic Energy

Temperature

Entropy

State of Disorder or Randomness. Ex. Solid is least Entropy, Gas is most.

Electronegativity

Attraction for electrons.

Ionization Energy

Energy needed to remove an electron.
