Verified step by step guidance

Understand the concept of exothermic reactions: These are chemical reactions that release energy, usually in the form of heat, to the surroundings. This is because the energy required to break the bonds in the reactants is less than the energy released when new bonds are formed in the products.

Consider neutralization reactions: These are a type of exothermic reaction where an acid and a base react to form water and a salt, releasing energy in the process.

Understand endothermic reactions: These reactions absorb energy from the surroundings, usually in the form of heat. This occurs because the energy required to break the bonds in the reactants is greater than the energy released when new bonds are formed in the products.

Consider decomposition reactions: These involve breaking down a compound into simpler substances. The energy change in decomposition reactions can vary; some are exothermic, while others are endothermic, depending on the specific reaction.

Identify the types of reactions that release energy: Based on the explanations, exothermic reactions and neutralization reactions are the types that typically release energy.
