Answer to Question #221395 in General Chemistry for Eli

Question

Given the following data:

SrO(s) + CO₂(g) ---> SrCO₃(s)ΔH = −234 kJ2SrO(s) ---> 2Sr(s) + O₂(g)ΔH = +1184 kJ2SrCO₃(s) ---> 2Sr(s) + 2C(s, gr) + 3O₂(g)ΔH = +2440 kJ

Find the ΔH of the following reaction:

C(s, gr) + O₂(g) ---> CO₂(g)

Answer 1

$\Delta H$ of formation =$3390kJ$
