Intermolecular Forces
When atoms in a molecule don't share charge equally.
What is polarity?
This many moles of NaCl are formed when Na2CO3 reacts with CaCl2.
What is 2?
When this type chemical reaction occurs, the system loses energy.
What is exothermic?
At this point in a reversible reaction, there is no net concentration change in reactants or products.
What is equilibrium?
This is what you call a substance that can donate or accept protons.
What is amphoteric?
While all molecules experience temporary dipole attractions, those with more electrons will experience these forces more.
What are London Dispersion Forces?
This type of reaction involves transfer of one or more electrons between chemical species.
What is oxidation/reduction?
What is calorimetry?
This describes the relative concentrations of reaction species at any time during a reaction.
What is the reaction quotient (Q)?
This is how you find the molar concentration of OH- if you know the pH.
What is subtraction the pH from 14, then raising 10 to the negative of that power?
These solids have very high melting points because it takes a lot of energy to disrupt their crystal structure.
What are ionic compounds?
This type of reaction forms CaCO3 from CaCl2 and Na2CO3.
What is a precipitation reaction?
This variable has the most influence on the kinetic energy of a molecule.
What is velocity?
If a reaction proceeds almost to completion, it has this.
What is a very large K?
NaOH and KOH are examples, but ammonia and aluminum hydroxide are not.
What is a strong base?
This technique separates substances based on their boiling points.
What is distillation?
These 4 things can change reaction rate.
What are concentration, temperature, surface area and catalysts?
Two substances will not warm the same given the same amount of heat if this characteristic differs.
What is specific heat capacity?
This happens when a reaction is reversed.
What is the inverse of K?
This helpful step is part of the process for figuring out equilibrium concentrations in an acid-base reaction when Ka is known.
What is 'make an ICE table'?
This type of matter has the lowest intermolecular forces.
What is a gas?
This exponent is associated with [A] in the rate law for the reaction A + B --> C, where the concentration of C quadruples for every doubling of the concentration of A.
What is 2?
A pure substance has this amount of Gibbs free energy.
What is 0?
The effect of altering the amount of a chemical species in a reaction can be predicted based on this.
What is Le Chatelier's Principle?
H3PO4 is a polypprotic acid that dissociates in water, with 3 different dissociation constants; a1 = 7 x 10-3, a2 = 6x10-8, a3 - 4 x 10-13.
Which do you use to determine the pH?
What is a1?
