CHM 1101

Solute what is being dissolved
Solvent what is doing the dissolving
Solution solute + solvent
Solubility amount of solute a solution can dissolve
What is the equation for Molarity? moles solute/volume of solution
What is the equation for Mass Percent? mass of solute/mass of solution x 100
What is the equation for Dilutions? C1V1 = C2V2
What is the specific heat of water? 4.184 J/g C
Exothermic process or reaction in which the surroundings absorb energy from the system
Endothermic process or reaction in which the system absorbs energy from the surroundings
An electron is QUANTIZED which means: it has a certain distance is must remain from the nucleus
As wavelength decreases, energy... increases
As wavelength increases, energy... decreases
Constructive Interference two waves, that are in sync with one another, will collide and reinforce each other
Destructive Interference two waves, that are NOT in sync with one another, will collide and cancel out
What is the equation for specific heat? q = sm(delta)T
What is the basic idea behind wave-particle duality? all matter exhibits both wave and particle properties
What is electronegativity? the strength of the pull of atoms
What does VSEPR stand for? Valence Shell Electron Pair Repulsion
Explain the VSEPR theory. Everything in a molecule bends away from an unshared pair of electrons
Which elements are allowed to break the octet rule? Any elements in or below the 3rd row on the periodic table, as well as Boron.
What are the three intermolecular forces, from weakest to strongest? London, Dipole-Dipole, Hydrogen Bonding
What are the two basic rules for Hydrogen Bonding to occur? A Hydrogen molecule must be present. The other molecule must be Oxygen, Nitrogen, or Fluoride.
What is the hydronium ion? H3O
Amphoteric substances that can be an acid or a base, depending on what it's reacting with
Conjugate Acid base after doing its job
Conjugate Base acid after doing its job
Acid + Base = Salt + Water
Acid + Metal Carbonate = Salt + Water + CO2
Acid + Metal Bicarbonate = Salt + Water + CO2
Buffer protects the pH of a solution
Equilibrium the condition where both reactions occur at the same rate
Dynamic Equilibrium concentrations remain constant but the individual atoms can switch places
What is the Collision Theory? explanation as to why reactions occur
What are the 3 principles of the Collision Theory? 1. molecules/atoms are in constant motion and will interact with one another (collide) 2. molecules/atoms must posses a certain minimum energy (activation energy) 3. molecules/atoms must have proper orientation
What is Le Chatelier's Principle? disturbing a reaction at equilibrium will force it to alter itself to compensate for that disturbance
