Answer:

1. The Atmosphere and Living Things

Carbon dioxide and oxygen are the gases in the atmosphere that are needed for life.

2. iron oxide will form. ... Iron,if exposed to oxygen,will have a chemical reaction that results to iron oxide,or rust,Other irons are non rustible,like stainless steels.

3. The oxygen-burning process is a set of nuclear fusion reactions that take place in massive stars that have used up the lighter elements in their cores.

4. Some common synonyms of decompose are decay, putrefy, rot, and spoil.

5. Background: Fruit turns brown when exposed to air because a reaction is happening when a cut piece of fruit is exposed to oxygen. ... The chemical reaction can be simplified to: Polyphenol Oxidase + O2 → Melanin (Brown Color) Oxygen activates the compound polyphenol oxidase in the fruit to turn the fruit brown.

3.Oxygen-burning process

The oxygen-burning process is a set of nuclear fusion reactions that take place in massive stars that have used up the lighter elements in their cores. Oxygen-burning is preceded by the neon-burning process and succeeded by the silicon-burning process.

4.Decompose

Some common synonyms of decompose are decay, putrefy, rot, and spoil. While all these words mean "to undergo destructive dissolution," decompose stresses a breaking down by chemical change and when applied to organic matter a corruption.
