Answer:
Ethylene oxide
Explanation:
Ethylene oxide is an organic compound with the formula C2H4O. It is a cyclic either and the simplest epoxied: a three-membraned ring consisting of one oxygen atom and two carbon atoms!
<span>Non-stoichiometric defects are </span>compounds which contain the combining elements in a ratio different from that required by their stoichiometric formula. The solids with metal excess <span>defect </span>contain metal in excess to the stoichiometric ratio. Such defect is caused due to either of the following reasons:
1. <span>Metal excess Defect due to Anionic Vacancies:
In this, </span>negative ions may be missing from their lattice sites leaving holes in
which the electrons remain entrapped to maintain the electrical
neutrality.
2. Metal excess defect due to the presence of extra cations at interstitial sites:
In this case, there are extra positive ions occupying interstitial
sites and the electrons in another interstitial sites to maintain
electrical neutrality. The defect may be visualized as the loss of
non-metal atoms which leave their electrons behind. The excess metal
ions occupy interstitial positions.
The more numbers after the decimal point there are, the more precise the instrument which recorded it is. For example, if one instrument during seismic activity records that the magnitude of the earthquake was 2.3, and another instrument recorded that it was 2.3645, the second instrument would have shown to be more precise.
