    • 9 Pages

    Hydrogen Peroxide & Inorganic Peroxy Compounds Hydrogen Peroxide Hydrogen peroxide (H2O2) is the simplest peroxide (a compound with an oxygen-oxygen single bond). It is also a strong oxidizer. Hydrogen peroxide is a clear liquid‚ slightly more viscous than water. In dilute solution‚ it appears colorless.  Reactions Decomposition Hydrogen peroxide decomposes exothermically into water and oxygen gas spontaneously: 2 H2O2 → 2 H2O + O2 This process is thermodynamically favorable. It has

    Aspects of Decomposition: A Brief Overview Kyle Jackman Animals are complex creatures. The animal can perform such tasks as reproduction‚ digestion‚ and simply movement. This is leaving out the more basic functions of respiration‚ circulation‚ and various maintenance functions. All of these processes are very complex‚ from the superficial all the way to the chemical level. Decomposition is one of these processes. It is common belief in our society to believe that death is an event‚ but

    occurs when the nuclei of atoms are changed. Hydrogen and uranium are two kinds of matter used to produce nuclear energy. In a nuclear reaction‚ the tremendous binding energy inside a hydrogen or uranium nucleus is released. Nuclear energy is released during atomic fission‚ when uranium nuclei are split. It is also released during fusion‚ when hydrogen nuclei combine to form a helium nucleus. In fission and fusion‚ nuclear energy produces thermal energy‚ which is given off as heat. Fission’s
