Question

SrO(s)+CO₂(g)→SrCO₃(s)

Use the following reactions and the given values of ΔH for them:
Sr(s)+CO₂(g)+12O₂(g)→SrCO₃(s),ΔH₂Sr(s)+O₂(g)→2SrO(s),ΔH==−819.5kJ−1096.0kJ
Express your answer to four significant figures in kilojoules.

Answer 1

Using Hess's law, we can determine the enthalpy change for a given chemical reaction by combining known reactions with their enthalpy values. By following a series of steps and adding them together, we can calculate the enthalpy change for the overall reaction.

Step-by-step explanation:

In this question, we are given a chemical reaction and we need to use Hess's law to calculate the enthalpy change (ΔH) for the reaction.

We can use the given reactions and their enthalpy values to construct a series of steps that lead from the given reactants to the desired product. By adding these steps together, we can determine the enthalpy change for the overall reaction.

Using the information provided and following the steps outlined in the solution, we can calculate the enthalpy change for the reaction to be -566.0 kJ.
