Energy is expended when a force moves matter across a distance. True False The conservation of mass-energy and the first law of thermodynamics are synonymous. True False Temperature and thermal energy are synonymous terms.

When potassium chromate (K2CrO4) is added to a solution containing 0.500 g silver nitrate (AgNO3), solid silver chromate (Ag2CrO4) is formed. a)  Determine the theoretical yield.

The equilibrium concentrations of the reactants and products are [ HA ] = 0.260 M [HA]=0.260 M, [ H + ] = 2.00 * 10 - 4 M [H+]=2.00*10-4 M, and [ A - ] = 2.00 * 10 - 4 M [A-]=2.00*10-4 M. Calculate the value of p K a pKa for the acid HA HA.
