Difference between word and symbol equation?

Moin,

a Language equation consists of words – as the name says!

The Symbol equation – also self-explanatory – consists of symbols of the chemical formula language.

The Reaction scheme (the Reaction equation) then consists of the symbols of the chemical formula language AND is balanced.

The fulldige reaction scheme (the complete reaction equation) also contains further information on the conditions of the substances involved or special observations in their own symbols.

An example:

Information text:
Aluminium reacts much more easily with oxygen than iron. It is therefore possible to obtain pure iron from iron oxides (for example iron(II) oxide if it is allowed to react with aluminum. A great deal of energy is released (thermal processes).

Equation:
Solid aluminum and solid iron II oxide react to solid aluminum oxide and elementary iron.

Symbol equation (preliminary equation):
Al + FeO –> Al₂O₃ + Fe

Reaction scheme:
2 Al + 3 FeO –> Al₂O₃ + 3 Fe

Full reaction scheme:
2 Al_(s) + 3 FeO_(s) –> Al₂O_3(s) + 3 Fe_(s) // strongly exothermic reaction

All right?
