Calculate Enthalpy For Reactions

Question

Consider these reactions, where M represents a generic metal.

1. 2M(s) + 6HCl(aq) → 2MCl3(aq) + 3H­2(g)                  ΔH1 = -881.0 kJ

2. HCl(g) → HCl(aq)                                                      ΔH2 = -74.8 kJ

3. H2(g) + Cl2(g) → 2HCl(g)                                          ΔH3 = -1845.0 kJ

4. MCl3(s) → MCl3(aq)                                                   ΔH4 = -316.0 kJ

Use the information above to determine the enthalpy of the following reaction

2M(s) + 3Cl2(g) → 2MCl3(s)                                      ΔH = __________ kJ

Summary

The question belongs to Chemical Engineering and it discusses about calculation of enthalpy for the reactions given in the question.

    Hello Allison,I love the 2nd image that you did! I also, had never heard of SumoPaint, is something that I will have to exolpre a bit! I understand completely the 52 (or so) youtube videos that you probably watched. Sometimes they have what you want, sometimes they don't! However, it is always satisfying when you are able to produce something that you have taught yourself. Great job!Debra 0 likes
