Here is the reaction you'll be calculating for: 2HCl (ag) + Ba(OH)2 (s) BaCl2 (ag) + 2H20 (1) You can consider the barium hydroxide, Ba(OH)2 , to be the limiting reactant. Data specific heat capacity of solution mass of barium hydroxide in grams volume of hydrochloric acid solution in milliliters molarity of hydrochloric acid solution in moles per liter Final temperature in degrees Celsius Initial temperature in degrees Celsius density of hydrochloric acid solution in grams per milliliter 1.055 4.18 J/gC 24.3435 100.50 1.82 20.5 36.1 Calculations: In this set of calculations you will try to find the molar heat of reaction for barium chloride reacting with hydrochloric acid in water. Go through the steps below and calculate the molar heat of reaction. A good approach would be to fill out the table below and be sure to put the appropriate units for each value. Some of the numbers you need are in the data set on the previous page. Others you will need to calculate. Fill in the table below and be sure it's organized and easy to read. You don't need to show your individual steps on a separate page. Mass of hydrochloric acid solution Change in temperature for reaction AH (use the definition AH = -MCAT) Mass of barium hydroxide Moles of barium hydroxide (use molar mass to convert) AH per mole of barium hydroxide AH per mole in units of kJ/mol (1 kJ=1000 J) Here is the reaction you'll be calculating for: 2HCl (ag) + Ba(OH)2 (s) BaCl2 (ag) + 2H20 (1) You can consider the barium hydroxide, Ba(OH)2 , to be the limiting reactant.
