Exothermic reactions produce heat. Endothermic reactions take in heat from the surrounding area and get cold.

What happens during chemical reactions From: Apex?
energy is given off or absorbed
What two kinds of energy changes can take place during a chemical reaction?
Two types of energy changes that can occur in a chemical reaction are (1) endothermic and (2) exothermic. Endothermic is where energy is added to the system and exothermic is where energy is given off by the system.
What do chemical changes always take in or give off?
Some reactions give off heat (exothermic), others absorb heat (endothermic). All reactions increase entropy.
What type of chemical reaction occurs energy is given out causing temperature to go up?
Exothermic reactions. Such as combustion or reactions whereby the energy required for bond forming is greater than the energy absorbed for bond breaking.
Endothermic and exothermic reaction?
An exothermic reaction releases energy, usually to the surroundings. There is a net loss of energy from the reactants. However, exothermic reactions also need a little energy to get started, but this is less than the eventual amount given out. An endothermic reaction takes in energy, also usually from the surroundings. There is a net gain of energy into the reactions. Again, a little energy is lost, but this is hardly anything compared to the amount taken in.
Which form of energy is released or absorbed in most chemical reactions?
If there is any type of energy given offduring a chemical reaction, it is most likely to be heat or light. However, heat and light often come together, and there are more reactions known to give heat without light than the other way around. Thus, I would go for heat then. (simply put)

Is energy given off or required when chemical bonds are formed?
Yes because if you put something together the energy will change. Or if you put a chemical ( Any kind) It would change the energy that it 2was before. What kind of form of energy is it though!

The substance produced a result of a chemical reaction is?
Depends what the chemical reaction is. In all reactions energy is given off. In lot's of reactions also water (Hyrdodgen Oxide/ H2O) and CO2 in some cases. Hope that helped.
What is a chemical reaction in which more energy is given off than taken in?
Combustion, burning, releases more heat that is taken in to start the reaction.
Endothermic and exothermic reaction?
An exothermic reaction releases energy, usually to the surroundings. There is a net loss of energy from the reactants. However, exothermic reactions also need a little energy to get started, but this is less than the eventual amount given out. An endothermic reaction takes in energy, also usually from the surroundings. There is a net gain of energy into the reactions. Again, a little energy is lost, but this is hardly anything compared to the amount taken in.
How are these last two chemical reactions alike different?
The question is quite vague, as there are many chemical reactions and none are specified, so the two chemical reactions must be specified before an answer can be given.
Why is chemical disequilibrium essential for life?
Chemical reactions need to keep moving in one direction or the other-- either giving off energy, or using it up. If chemical reactions were at equilibrium, no energy is being absorbed nor given off, therefore nothing would happen.
What is the name given to chemicals before they undergo chemical reactions?
They are reactants.
