To find the enthalpy of a reaction in the lab, you measured the of the reactants and the change during the reaction.

Pl what kind of reaction is this? nahco3 + h2o → co2 + naoh + h2o -composition -decomposition -single replacement -double replacement im leaning more toward single replacement. if im wrong can you explain whyy?
