Data and Observations Calcium Temperature Grams 4.18 x AT x g AH AS (From #2 Grams Mole T AT Water (g ams Water) Below) 1 n 100. -12.8 2 t. Average AH 2.8 1. Balance the chemical equation of calcium with water to produce calcium hydroxide and hydroge gas. la 2. List the reference values for AG of each reaction component. Using those values, and the average of the experimentally determined value for AH in this experiment, report a semi-experimental value for AS. Compare this value to the theoretical value. What would cause any variance Reaction Comp. AGO (semi-exp) (theoretical) 57.6 2, 131,Explanation / Answer
Ans 1 - This reaction is an exother mic reaction in which heat is released -
the reaction is -
Ca(s) + 2 H2O(l) -----------> Ca(OH)2(aq) + H2(g) + Heat
