The answer is oxygen
yes it does <><><> No- some reactions ABSORB energy. In terms of heat energy, some are exothermic, and some are endothermic.
Activation energy is needed to start a chemical reaction. This energy is used to join the reactants together or break them apart. If a reaction is exothermic then it gives energy out. If it is endo thermic then the reaction takes energy in.
The energy contained in organic molecules is a form of chemical energy. This energy is stored within the bonds of molecules and can be released through chemical reactions, such as cellular respiration, to fuel various biological processes.
An exothermic change is a chemical reaction that releases heat to its surroundings, resulting in an increase in temperature. This type of reaction gives off energy in the form of heat as the reactants are converted to products. Examples include combustion reactions and many types of oxidation reactions.
A chemical reaction that produces energy is said to be exothermic. In comparison, if it consumes energy it is endothermic.
iron
Energy is from glucose.

Metabolism is the group of chemical reactions that takes all of the energy from your food and gives it to the rest of your body for energy.
All chemical reactions that release energy in the form of heat are called exothermic reactions.
Activation energy is needed to start a chemical reaction. This energy is used to join the reactants together or break them apart. If a reaction is exothermic then it gives energy out. If it is endo thermic then the reaction takes energy in.
If by energy you mean heat energy exothermic reactions.
Some reactions give off heat (exothermic), others absorb heat (endothermic). All reactions increase entropy.
The sun gives off solar energy, but the sun runs on chemical/nuclear reactions, fusion, converting hydrogen-1 to helium-4.
An exothermic reaction is a chemical reaction that is done by the release of heat. It gives out energy to its surroundings. The energy needed for the reaction to occur is less than the total energy released.
The scientific name for the reaction that gives out energy is exothermic
Francium is a radioactive chemical element an can disintegrate.
