Answer to Question #190539 in General Chemistry for Maddie Dalton

Question

2 CaCO₃(s) + 2414 kJ  2 Ca(s) + 2 C(s) + 3 O₂(s)

Complete the thermochemical equation in ΔH_rxn format, for the reaction above.

2 CaCO₃(s) + 2414 kJ  2 Ca(s) + 2 C(s) + 3 O₂(s)     

ΔH_rxn =  --------kJ

Answer 1

2CaCO₃(s) + 2414 kJ = 2Ca(s) + 2C(s) + 3O₂(s)     

ΔH_rxn =  +2414kJ.
