The reactions that take place on the sun are nuclear fusion reactions. Stars are, after all, giant nuclear fusion engines. On our neighborhood star, hydrogen is being fused into helium in the proton-proton chain. In this reaction, two protons are fused and one of them undergoes a beta decay to become a neutron, producing deuterium. There are a couple of different ways the fusion reactions can go from there, but helium eventually results. The process by which stars "run" is called stellar nucleosynthesis, and you can use the links below to investigate further.
Generally in a body two type of reactions take place, catabolic and anabolic. Catabolic reactions are the type of reactions in which bio-molecules in our body split into their constituents to release energy; while anabolic reactions are those reactions in which new bio-molecules are synthesized in our Body. Together both reactions are known as METABOLISM.
Biochemical reactions are taking place when fruit ripens.
The best thing to do is contact your local garbage collection department, recycling center or local government offices. Most towns have programs in place to dispose of this type of material.

exothermic reactions
Light reactions in plants occur in the thylakoid membranes of chloroplasts, where light energy is captured by chlorophyll and converted into chemical energy in the form of ATP and NADPH. These energy carriers are used in the later stages of photosynthesis to drive the synthesis of glucose.

For chemical reactions, the elements in a sealed vessel will not change. But, reactions can take place that would tend to take the sample to a state of equilibrium. Or, with heating or cooling the physical state can be changed.Another type of reaction is nuclear decay, in which radioactive substances will spontaneously decay to other radioactive substances, or decay to non-radioactive substances, thus actually changing the elements present.
