- Each molecule in our body has a unique shape.
- A water molecule is composed by three atoms: two hydrogen and one oxygen.
- A molecule of water is made up of one oxygen and two hydrogen atoms.
- position of labelled atoms in the molecule.
- It contains 1/4 molecule of NaOH Chemical name
- Citric acid may be anhydrous or it may contain 1 molecule of water.
- There are no chemical groups associated with explosive properties present in the molecule.
- An organic peroxide is any organic molecule containing a ‘peroxy’ or oxygen-oxygen bond (-O-O-).
- Tartaric acid is a ‘chiral’ molecule, i.e. it exists in different geometric configurations.
- There are no chemical groups present in the molecule associated with explosive or self reactive properties.
- Not less than 2,500 kgm-1s-1 at 25 oC corresponding to an average molecule weight of 5000 D
- ABC corresponds to the atomic number of the most characteristic element or the most characteristic organic group in the molecule.
- labelling of the most stable part of the molecule ensures the determination of the total mineralisation, while 14C labelling of a less stable part of the molecule, as well as the use of specific analysis, enable the assessment of only primary biodegradation. However, the most stable part does not necessarily include the relevant functional moiety of the molecule (that can be related to a specific property such as toxicity, bioaccumulation, etc.).
- For metal availability, the extent to which the metal ion portion of a metal (Mo) compound can disaggregate from the rest of the compound (molecule).
- ‘hydrofluorocarbon’ means an organic compound consisting of carbon, hydrogen and fluorine, and where no more than six carbon atoms are contained in the molecule;
