### Determining Reaction EnthalpyUsing the given equations:1. \( \text{SrO (s) + CO}_2 \text{(g) → SrCO}_3 \text{(s)} \quad \Delta H^\circ = -234 \,\text{kJ/mol} \)2. \( 2\, \text{Sr (s) + O}_2 \text{(g) → 2 SrO (s)} \quad \Delta H^\circ = -1184 \,\text{kJ/mol} \)3. \( \text{CO}_2 \text{(g) → C (s) + O}_2 \text{(g)} \quad \Delta H^\circ = 394\, \text{kJ/mol} \)The task is to determine the enthalpy (in kJ/mol) for the reaction:\[ \text{2 SrCO}_3 \text{(s) → 2 Sr (s) + 2 C (s) + 3 O}_2 \text{(g)} \]If you follow through the enthalpy calculations and manipulations using Hess’s law and the given equations, the detailed explanation would include reversing some reactions and properly scaling them to match the coefficients needed for the target equation, and finally summing their enthalpy changes to find the reaction enthalpy. For educational purposes, it is crucial to show all the steps and manipulations in detail so students can follow and understand how to apply Hess's Law in solving enthalpy problems involving multiple steps. **Using the equations:**\[2 \text{Fe} (s) + 3 \text{Cl}_2 (g) \rightarrow 2 \text{FeCl}_3 (s) \quad \Delta H^\circ = -800.0 \, \text{kJ/mol}\]\[ \text{Si}(s) + 2 \text{Cl}_2 (g) \rightarrow \text{SiCl}_4 (s) \quad \Delta H^\circ = -640.1 \, \text{kJ/mol}\]**Determine the enthalpy (in kJ/mol) for the reaction:**\[3 \text{SiCl}_4 (s) + 4 \text{Fe} (s) \rightarrow 4 \text{FeCl}_3 (s) + 3 \text{Si} (s)\]
