Wood is made from carbon, chemical reaction: C
+ O₂ → CO₂.
Law of conservation of matter states
that for any system closed to
all transfers of matter and energy, the mass of
the system must remain constant over time.
In chemical reactions, the mass of
the chemical components before the reaction (in this reaction carbon and
oxygen) is equal to the mass of the components after the reaction (carbon
dioxide).
Number of atoms on the left side of reaction and on the right of reaction must be the same.
