Released. The energy that brings the atoms together is given off when they combine. Remeber energy can be neither DESTROYED or created.
absorbed
Chemical bonds are formed and energy is released.
Yes; for example, two oxygen atoms combine to form an oxygen molecule.
NADP+
NO!!! It is a monatomic atom. It is inert so it does not combine with anything to form a molecule.
absorbed
Methane need not combine with anything to create a molecule. It by itself is a molecule.
Chemical bonds are formed and energy is released.
A molecule/compound
yes
a molecule
a molecule
It is sort of tricky question. One molecule of carbon can combine with only one molecule of oxygen. It can not combine with two molecules of oxygen. Incidentally one molecule of carbon is composed of one atom of carbon. One molecule of oxygen is composed of two atoms of oxygen.
Atoms that chemically combine form a molecule.
Its a molecule and it combines carbon.
they form a molecule
Nothing. A molecule is a pure substance if it is of one element.
