A+BX--→ AX+B Sentence example: iron reacts with steam to form metal oxide and hydrogen gas. (3Fe+4H2O-→ Fe3O4+4H2)

You can change the sentence into an equation by turning iron into Fe, and reacts into plus sign, then steam becomes 4H2O to form becomes an arrow metal oxide becomes Fe3O4 the and becomes a plus sign then the hydrogen gas becomes 4H2.

Balancing the equation:

_Fe+_H2O-→ Fe3O4+_H2 becomes… 3Fe+4H2O-→ Fe3O4+4H2**
