What is true for the following reaction? ca(s) + 2c(s) cac2(s) + 62.8 kj it is an endothermic reaction and ∆h= +62.8 kj. it is an endothermic reaction and ∆h= -62.8 kj. it is an exothermic reaction and ∆h= +62.8 kj. it is an exothermic reaction and ∆h= -62.8 kj. this reaction will not occur.

If i am reading correctly, the heat amount (+62.8Kj) is on the right side of the reaction. 

If the heat is on the products (right side of the reaction), that means the reaction is exothermic (heat is released as a product). exothermic reactions have negative ΔH values. so the values for this ΔH= -62.8 kj.

the answer is "It is an exothermic reaction and ∆H= -62.8 kJ"

D. is the answer hope that you
