What is enthalpy change ?
Gas constant 0.08206 L*atm/mol
What is R?
The number of shared cells in a edge cell
What is 4?
Point at which stoichiometrically equivalent quantities of acid and base have been mixed together
What is equivalence point?
△S total > 0
What is reaction is spontaneous ?
State reached when the concentration of reactants and products remain constant over time
What is chemical equilibrium?
Total number of atoms in a body-centered cell
What is 2 atoms? (1 atom corner + 1 atom body)
The pH at the equivalence point of a strong acid-strong base tritiation
What is pH = 7.00?
The surroundings loses heat and entropy decreases

Procedure for determining the concentration of a solution by allowing a unknown solution to react to a known substance
What is titration?
Examples would include: HCIO4 , HCl , H2SO4 , HNO3
What are strong acids?
Free energy change under nonstandard conditions
What is △G?
If a stress is applied to a reaction mixture of equilibrium, net reaction occurs in the direction that relieves the stress
