Chemical Reactions
This reaction involves two compounds exchanging ions like dance partners.
What is a double replacement reaction?
If you have 38.90 g of phosphorus, this is the number of moles you have (30.97 g/mol).
What is 1.256 moles?
This law states pressure and volume are inversely proportional at constant temperature.
What is Boyle's Law?
If ΔHrxn = -213 kcal/mol, this type of reaction releases heat.
What is exothermic?
The strongest IMF in CH3Cl.
What is dipole-dipole?
This reaction type occurs when two substances combine to form one product.
What is a combination reaction?
This reactant produces less product in a reaction and limits it.
What is the limiting reactant?
A 5 atm, the sample heated to 90°C reaches 6 atm. This is the initial T in K.

What is 325 K?
Increasing the temperature in this reaction shifts equilibrium to the reactants.
What is exothermic reaction?
This compound melts easier: one with weak or strong IMF?
What is weak IMF?
This reaction type involves a single element replacing another in a compound.
What is a single replacement reaction?

This happens to pressure when heating a closed container of gas.
What is increases?
ΔH negative indicates this.
What is heat is released?
These bonds occur between H and highly electronegative atoms like O.
What is hydrogen bonds?
Breakdown of a compound into two or more simpler substances is this reaction.
What is a decomposition reaction?
Balance Zn + HCl → ZnCl2 + H2.
What is Zn + 2 HCl → ZnCl2 + H2?
This is the equation that relates P, V, n, R, and T.
What is PV = nRT?
This is the energy change of a reaction.
What is enthalpy (ΔH)?
These forces exist between all molecules due to temporary dipoles.
What is London dispersion forces?
