Question
Write the chemical equations for all parts (a-f) shown above. The purposes of this experiment are To introduce you to calorimetric. To use Hess law of enthalpy summation and To find the enthalpy of formation of solid ammonium cloned. Chemical Overview The standard enthalpy of formation. AH. is the AH of a reaction in which one mole of a substance is formed from it's ments . all substances being at their standard states at one atmosphere and 25 degress C The only substance on the right side of a heat of formation equation is one mole of the compound in question The left side has only the elements present in the compound To balance such an equation, you sometimes have to use fractional coefficients for diatomic elements, such as O2. Cb. etc. For example, the heat of formation equation for solid KCIO3 would be K(s) BrExplanation / Answer
(a) enthalpy of formation of gaseous ammonia
N2 (g) + 3/2 H2 (g) ----------------------------> NH3 (g)
(b) heat of solution of gaseous NH3
NH3 (g) + H2O (l) --------------------> NH3 (aq)
(c) enthalpy of formation of HCl (g)
1/2 H2 (g) + 1/2 Cl2 (g) -------------------> 2HCl (g)
(d) heat of solution of gaseous HCl
HCl (g) + H2O (l) ---------------------> H+ (aq) + Cl- (aq)
(e) NH3 (aq) + HCl (aq) -------------------> NH4Cl (aq)
(f) NH4Cl (s) + H2O (l) ----------------------> NH4Cl (aq)
