No it is not!
When a substance dissolves completely and evenly in another substance, a homogeneous mixture called a solution is formed. In a solution, the solute (the substance being dissolved) is uniformly distributed in the solvent (the substance doing the dissolving).
Yes, it is a almost unlimited number of complex chemical reactions: at least carbon dioxide and water vapor are some of the substances formed by burning.
The point at which the greatest possible amount of a substance has been absorbed by a solution at a given temperature. Any excess amount of that substance will "fall out" of the solution as a precipitate. Saturation point occurs when water being evaporated equals the amount being condensed. -Qwasas

This substance is called catalyst.
a process that does not change the chemical composition of a substance. A change in a substance with no new substances being formed
A physical change, such as melting ice or cutting paper, does not result in a new substance being formed. These changes only affect the physical state of the matter, not its chemical composition.
The title of the charge varies from state to state. Typical statute titles are "Possession of a controlled substance" or "Possession of a dangerous drug."
The Himalayas are constantly being formed and changed through tectonic plates shifting under the Earth's surface. It is an extremely slow process which occurs over millions of years.
