Question

Please verify if these calculations are correct. If there is an issue, please walk through what I did wrong. Specific heat is 4.18 J/(g×°C)

Explanation / Answer

Corrections,

NaHCO3,

q = 717.3032 J

dH = -3.014 x 10^4 J/mol

      = -30.14 kJ/mol

---

Na2CO3

q = -630.3513 J

dH = 3.32 x 10^4 J/mol

      = 33.18 kJ/mol

---

Rest of calculations are correct
