Question

17. Calculate ƒ´H of strontium carbonate using Hess law

Sr + C (graphite) + 3/2 O2 ¡÷ SrCO3

Experimental information

SrO ¡÷ Sr + 1/2 O2 ƒ´H 592 kJ

SrO + CO2 ¡÷ SrCO3 ƒ´H -234 kJ

2 C (graphite) + 2 O2 ¡÷ 2 CO2 ƒ´H -788 kJ
.

Answer 1

I've shown you how to do these above. Try your hand at this. There is little I can do except do it for you and I don't want to do that. If you still have trouble explain in detail what your problem is and I'll try to help you through it.
