Calculate the equilibrium concentration of HC2O4- in a 0.20 M solution of oxalic acid.
Given that we start with 0.036M NO(g) and 0.036M O2(g) AND end with 0.014M NO2, what is the equilibrium constant for this reaction and what are the equilibrium concentrations for NO and O2?
total of 2.00 moles of a compound is allowed to react in a foam coffee cup that contains 122 gm of water. The reaction caused the temperature of the water to rise from 21.0 to 24.7
An unknown metal weighing 13.11 g at a temperature of 81.0*C is placed in a calorimeter containing 25.0 mL of water at a temperature of 25.0*C. The final equilibrium temperature is 30.0*C. What is the specific heat of the metal?
