This is the electron structure.
The colliding species must have the necessary activation energy and the correct orientation.
When heat/energy is added, static hydrogen bonds are unmade which cause water to be in a solid crystal-like structure, and the water molecules are freer to link up new hydrogen bonds with other water molecules or other electronically polarised molecules or others with a hydrogen, oxygen or nitrogen atom.
Both produce new molecules.
Metamorphism will alter the chemical molecules in a rock as it cools down, Otherwise, weathering will alter old molecules and create new ones.
It is a chemical because it is producing a new substance.

A project engineer is responsible for the building and producing of plans for the structure of a project. The project engineer also designs the plans using traditional and new technology. The project engineer also works with the project manager to ensure the plans are completed.
a chemical change destroys the old atoms and molecules to make completely new ones and a completely new substance.
No, when water turns to ice, no new molecules are formed. The molecules in water rearrange themselves into a crystal lattice structure when they freeze, but the individual water molecules remain the same.
Hydrogen pump.
In a nutshell, this individual was responsible for producing new variations of plants with favorable characteristics. His most famous finding was the production of a large, heavy potato.
The colliding species must have the necessary activation energy and the correct orientation.
Molecules can be divided into smaller molecules and then form new molecules again.
Banks are supplied with new coins and banknotes from whatever central banking agency is responsible for producing or distributing them. A bank is the only place the general population and businesses should be able to get new coins and banknotes.
liquid when it is in solid form, the molecules actually move further apart, which is unusual, since in most other cases the solid is the most dense. It is due to the structure of water molecules
by producing new plants (seeds) or dying-producing litter and supplying nitrates for new plants to grow.
