The unbalanced equation is one in which the moles of atoms are not equal on both sides of the reaction. 
<h3>What is a balanced chemical equation?</h3>
A balanced chemical equation is one in wgich the moles of atoms in the reactants side is equal to the moles of atoms on the product side.
The given equations of reaction is not clearly stated.
Therefore, the unbalanced equation is one in which the moles of atoms are not equal on both sides of the reaction.

Answer:
Endothermic reaction chemical equation
Reactnt A + Reactant B + Heat (energy) ⇒ Products 
Exothermic reaction chemical equation
Reactnt A + Reactant B ⇒ Products + Heat (energy)
Explanation:
Endothermic Reaction
An endothermic reaction is a reaction that reaction that requires heat before it would take place resulting in the absorption of heat from the surrounding that can be sensed by the coolness of the reacting system
An example of an endothermic reaction is a chemical cold pack that becomes cold when the chemical and water inside it reacts
Exothermic Reaction
An exothermic reaction is one that rekeases energy to the surroundings when it takes place. This is as a result of the fact that the combined heat energy of the reactants is more than the chemical heat energy of the products. An example of an exothermic reaction is a burning candle
