Tính sinh nhiệt tiêu chuẩn của ca(oh) 2 H2+1/2O2-h20 ∆h=-66, 3

CaO+h2O-Ca(oh)2-∆H=-15, 3

Ca+1/2O2-CaO ∆h=-151, 6

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.
