After two decades, 95 percent of the elemental mercury on the surface of a filling had gone through a chemical reaction. It became beta-mercury sulfide, a black-colored solid.
Volcanic heat would drive the chemical reactions, as well as causing lots of evaporation.
Researchers have long known that greenhouse gases might help the layer recover by cooling the stratosphere, which slows the rates of chemical reactions that destroy ozone.
a reversible chemical reaction; a reversible cell.
In fact, the chrome yellow chemical reaction occurred between the layers of varnish and paint.
Etch - a process of chemical reactions or physical removal to rid the wafer of excess materials.
If people do something together at the same time (synchronous behavior) it bonds them together-there are actually chemical reactions in the brain.
This chemical reaction generates a lot of heat.
A representation of a chemical reaction, usually written as a linear array in which the symbols and quantities of the reactants are separated from those of the products by an equal sign, an arrow, or a set of opposing arrows.
If you pause for a second and think of the many colours, shapes and textures around us, they are all the product of specific and unique chemical reactions that take place within.
But the whole process of ion movement and chemical reaction is slower than the movement of electrons in a capacitor.
Under anaerobic conditions (where oxygen is absent) they metabolise the fuel by feeding off it and in doing so produce natural chemical reactions that produce a current.
Such a structural distribution characteristic, which can be taken as a kind of structural signals for recognizing the splice sites, is in accordance with the chemical reaction mechanism of splicing.
A reactor is a container for chemical reaction.
Newton and his peers believed it was possible to prompt metals to grow, or "vegetate," in a flask. After all, many chemical reactions were known to leave lovely dendritic residues in their wake.
The equation for this chemical reaction is the reverse of one we have just been studying.
Once light is absorbed in plant leaves, it energizes an electron which is subsequently used to support a biochemical reaction, like sugar production.
The most important is temperature: the rate of chemical reactions in a cadaver doubles with each 10 degree Celsius rise.
