Fevicol is a PVA glue. PVA is relatively harmless, and the solvent is water. Some pva glues contain fungicides, so you don't want to drink it but the headline is "non-toxic".
Americium is oxydable in air.
The pyrite inclusions in lapis lazuli make it toxic
It is not toxic, extended inhalation can cause you to pass out if you do not have oxygen.
Methyl mercury is more toxic
NO. Hydrogen gas is non-toxic. However, it can displace oxygen (and if hot enough burn in it) and thus can be an asphynxant in large quantities. But hydrogen by it self is not toxic at all.
Fevicol is an adhesive marketed to carpenters that is designed to be used on woods, paper, cardboard, and fabrics. Fevicol is not water soluble. The glue has to be boiled in water before application.
gums are polymeric substances whereas fevicol is a polyvinyl alchol gum .It is not a polysaccharides.
Drying of fevicol is a chemical change obviously !! Its because we cannot bring back the original properties of fevicol whatsoever we do to it !!! ---------------------------------------------------- But evaporation of solvents is a physical process.

No, You cannot mix fevicol and fevibond because both of them have different media. i.e. fevicol is water-based while fevibond is rubber-based adhesive. Aquarium has to be filled with water and so, you cannot use fevicol as fevicol is likely to melt again within few hours. Its better if you go for feviquik first and stick the glasses and then make a lining of fevibond to ensure no water-leakage.

Fevicol from the general appearance and smell looks like its is a compound of EVA Ethelene Vinyl Acetate along with some extenders, these offer excellent bonding properties and cure to a film which is peelable. The important property is that the adhesive has a porperty of whetting the substrate and hence it is excellent for porous sunstrates like wood.

Actually it is a PVA glue. PVA stands for Polyvinyl Acetate.
