Name that Term (Definitions)
A molecule that donates protons or H+ ions
What is an acid?
Used to report molality
What are moles/g or moles/kg?
The process of slowly reacting a base of unknown concentration with an acid of known concentration until just enough acid has been added to react with all the base allowing the determination of the unknown concentration.

The energy from the nucleus of an atom.
What is nuclear energy?
A molecule that accepts protons or H+ ions
What is a base?
Used to report ideal gas law constant

What is J/goC?
A process that generates heat.
What is exothermic?
T/F The boiling temperature of a liquid decreases with added solutes.

Energy that is stored
What is potential energy?
Amount of heat necessary to raise the temperature of 1 g of a substance by 1oC
What is specific heat?
Used to report enthalpy of formation.
What is J, kJ, cal. or kcal PER mole?
(delta)H is negative for this reaction
What is exothermic?
In a constant T closed gas system, the pressure decreases with increased volume.
