Answer:
The answer to your question is: letter A
Explanation:
a) A + B ⇒ AB + heat It is an exothermic reaction because heat is released.
b) A + BΔ ⇒ AB It heat added to the reactants , then it is an endothermic reaction.
c) heat + BC ⇒ B + C It's an endothermic reaction because heat is added to the reactants.
d) B + heat + CD ⇒ BD + C It's and endothermic reaction because heat is added to the reactants.
Answer:
The correct answer is a"
Explanation:
Hello! Let's solve this!
Exothermic reactions are those that release heat and endothermic reactions are those that consume heat.
a) A + B ⇒ AB + heat
It indicates that heat is released by what is an exothermic reaction.
b) A + BΔ ⇒ AB Heat is added to the reaction so it is endothermic
c) heat + BC ⇒ B + C
It is an endothermic reaction because heat is consumed in the reaction.
d) B + heat + CD ⇒ BD + C
It is an endothermic reaction since it consumes heat
The correct answer is a"
