I may not be right, but I think an endothermic reaction uses chemical energy.

What is the type of heat reaction which occurs when heat is given off by the reaction?
Heat is released during an exothermic reaction.
If the reaction gets hot is it an endothermic or an exothermic reaction?
The reverse reaction is not always endothermic or exothermic, the reverse reaction is the opposite of whatever the initial reaction is, so if the reaction is endothermic, the reverse reaction is exothermic and vise versa.
Why do endothermic reactions need additional energy to keep going while exothermic reactions don't?
Ipso facto. An endothermic reaction "absorbs" energy (uses it to create high-energy bonds), so this must be constantly supplied from an external source. An exothermic reaction "releases" energy, and this energy can be used to continue the reaction until there are no reactants remaining.This is why stellar cores cannot fuse massive quantities of elements heavier than iron. The reactions are not self-perpetuating as they are absorbing energy rather than releasing it. A large, inert iron core is the result.
Why respiration is considered an exothermic reaction?
An exothermic reaction is one in which heat or energy is released, and that occurs in respiration. That is how the body uses respiration -- to get energy. If it were an endothermic reaction we would need to put energy into the process and not get energy out.
How might a thermometer help you decide if there was any chemical change on mixing iron and charcoal?
For a chemical change to occur, there must be a chemical reaction. A chemical reaction would be either endothermic (uses energy, mostly heat), or exothermic (produces energy, again mostly heat). Any change in temperature of the reactants, as measured by a thermometer, will tell you not only ifa chemical reaction occurred, but also which kind of chemical reaction. No temperature change usually indicates that no reaction has occurred, a decrease in temperature would indicate an endothermic reaction, while an increase in temperature would indicate an exothermic reaction.
What happens to energy in an endothermic reaction?
An endothermic reaction is a reaction which requires energy. The enegry is required for the reaction to take place, maning the energy is used up in the reaction. An example of an endothermic reaction is photosythesis.
What is A reactant in which energy is taken in?
You probably mean "what reaction releases energy," in which case, lots. Reactions that release energy into the environment are called exothermic reactions. An example of which would be mixing sodium (Na) and water (H2O) to form sodium hydroxide (NaOH), hydride (H2), and heat/energy. 2Na + 2H2O ---> 2NaOH + H2 + heat/energy

Is evaporation os exothermic or endothermic process.explain?
Physical endothermic change because it uses energy (taking up heat)

Is exercise of a body an exothermic and endothermic?
As you exercise your body uses stored fuel and turn it into energy to power mechanical movement. In this process, energy in the form of heat is released in to the surroundings. Therefore this is an exothermic process.
Is evaporation an exothermic or endothermic process explain?
It will be an endothermic process because the beaker becomes cool after evaporation.
If a chemical reaction uses up energy the reaction is .?
endothemic

When a cell uses chemical energy to perform work it uses the energy released from?
Exergonic reaction - which releases energy
