Reagent Potential Hazards Associated Safety Precautions That Should with this Reagent be Taken When Handling This Valins Reagent NaOH (concentrated solution and pellets) Moto HCI to mnogo wamu 2. When procedures 2 and 3 are finished, what chemical test could you perform to determine which reagent was in excess? 2015 3. Write and balance the equation for Part 2 4. Look up standard enthalpies of formation (i.e. heats of formation) for each species in the equation you wrote in Pre-lab question 3. You will use these values and the balanced equation to calculate the molar enthalpy change, AH, for the reaction in part 2 in Post-lab question 5a. Hint: If your text book contains only some of the values for standard enthalpy of formation for each reactant and product in this reaction, consult additional sources. Be mindful of states of matter when looking up and recording values.
