A wide variety of chemical reactions, both aerobic and anaerobic, occur to decompose the various tissues of a body. Perhaps what you may be interested in is the gases produced, methane, hydrogen sulfide (which smells like rotten eggs), ammonia, and those primarily responsible for the smell of corpses, putrescine and cadaverine. These foul smelling chemicals are not very toxic, and according to the UN, the greatest danger posed by corpses is the diseases attracted scavengers may bring.

What is gas needed for?
Oxygen is the gas that is required for respiration.
What element is a dangerous gas released by rock and soil?
Radon gas is a naturally occurring radioactive element which can be produced by the decay of radium (which in turn is part of the decay chain of uranium) present in granitic rocks and shales and also soils derived from these two rock types.
What makes helium?
The decay of uranium emits lots of alpha particles and a natural gas pocket tends to be a sealed container underground. Helium is cryogenically distilled out of natural gas to produce the helium.
Which element is a dangerous gas released by rocks and soil?
The radioactive decay of uranium and thorium minerals in igneous rocks such as granite can cause the release of the gas Radon which is dangerous to humans. The breakdown (anaerobic decay) of biological materials in soils and rocks at shallow depths can also produce methane gas which can be explosive or potentially cause asphyxia by displacement of oxygen at high concentrations.
What is the gas needed by the cells of the body?
For all animals: oxygen.
What gas helps decay to occur?
Any gas helps decay to occur.
Odor less radioactive gas produced from uranium decay?
This gas is radon.
A noble gas that is produced when radium undergoes radioactivity decay?
Yes, radon is a decay product in the uranium, thorium and actinium decay series.
Why is there less decay in frosty conditions?
because there is no warmth and humidity in the air which is needed by microbes in the process of decay thats why less decay occurs in frosty conditions
Why do corpses make a moaning sound?
If a corpse has not been embalmed, it will decay, and the process of decay produces methane gas, and when the gas escapes from the corpse it can produce a moaning sound.
Which noble gas occur when decay of uranium and radium occurs?
This noble gas is radon.
What is time needed for half the atom to decay?
about 5,730 years
What radon gas is produced?
Radon is a natural chemical element; it can be found inthe radioactive decay series of uranium, thorium.
What three conditions are needed for a plant material to decay?
moisture, warmth and oxygen
What is the time needed for half the atoms to decay called?
it's half life
What is the radioactive gas produced when uranium and thorium decay?
Isotopes of radon (Rn)
Where did radon originate?
Radon is a radioactive gas in the decay series of uranium and thorium.
