Given the standard enthalpy changes for the following two reactions:1. \( \text{Hg(l) + Cl}_2\text{(g)} \rightarrow \text{HgCl}_2\text{(s)} \) \(\Delta H^\circ = -224.3 \, \text{kJ}\)2. \( \text{Fe(s) + Cl}_2\text{(g)} \rightarrow \text{FeCl}_2\text{(s)} \) \(\Delta H^\circ = -341.8 \, \text{kJ}\)What is the standard enthalpy change for the reaction:3. \( \text{Hg(l) + FeCl}_2\text{(s)} \rightarrow \text{HgCl}_2\text{(s) + Fe(s)} \) \(\Delta H^\circ = ?\)---Below the question, there is a text box for entering the answer (in kJ) and two buttons labeled "Submit Answer" and "Try Another Version." There is also a note that says "3 item attempts remaining."

The reactions given are, Subtracting reaction 2 from reaction 1 will give the required reaction 3 (on subtracting reactions, the ΔHo of reactions also gets subtracted as per the Hess's law) as, => Hg (l) + FeCl2 (s) → Fe (s) + HgCl2 (s) ΔHo = -224.3 - (-341.8) = 117.5 KJ Hence the answer is 117.5 KJ.

A calorimeter contains 24.0 mL of water at 11.0 °C. When 2.20 g of X (a substance with a molar mass of 52.0 g/mol) is added, it dissolves via the reaction and the temperature of the solution increases to 25.0 °C. Calculate the enthalpy change, AH, for this reaction per mole of X. Assume that the specific heat of the resulting solution is equal to that of water [4.18 J/(g · °C)], that density of water is 1.00 g/mL, and that no heat is lost to the calorimeter itself, nor to the surroundings. Express the change in enthalpy in kilojoules per mole to three significant figures. ► View Available Hint(s) AH = X(s)+H2O(1)→X(aq) VE ΑΣΦ ? kJ/mol

In a constant‑pressure calorimeter, 55.0 mL of 0.340 M Ba(OH)2 was added to 55.0 mL of 0.680 HCl. The reaction caused the temperature of the solution to rise from 23.90 ∘C to 28.53 ∘C. If the solution has the same density and specific heat as water, what is heat absorbed by the solution? Assume that the total volume is the sum of the individual volumes. (And notice that the answer is in kJ).
