3. Considering the techniques and instrumentation used to perform these experiments, identify 2 potential sources of error if you were to repeat this experiment in the "real world". Human error is not an acceptable answer. Discuss at least two possible sources of error that could contribute to your percent error. A student is performing Reaction 2 and does not completely dissolve the NaOH pellets before acquiring the final temperature. How will this affect his value for AH, and his percent error calculations?

The following reversible enzymatic reaction occurs in many areas of the body, but especially in red blood cells. The conversion of water and carbon dioxide into bicarbonate and hydrogen ions occurs through the action of an enzyme called carbonic anhydrase. Use the Law of Mass Action to predict which direction this equation will go under different circumstances. CO2 + H2O ↔ H+ + HCO3- Hyperventilating would increase the loss of carbon dioxide (CO2) from the blood. In what direction would the reaction above go in order to restore equilibrium? Left or right?
