Question

Why is the following equation invalid? Al + 202 → Al2O3

Answer 1

Answer:

C. The equation violates the Law of Conservation of Mass

Explanation:

This equation is invalid because it violated the Law of conservation of Mass. The correct option is C.

This law establishes that the mass is not preserved or destroyed, but transformed.

That is why in a chemical reaction, the number of atoms involved in the reagents and products must be equal.

to achieve this it is necessary to perform a reaction adjustment.

The correct equation would be:

                                            $2Al + 3O_{2}$  ⇄  $2Al_{2} O_{3}$
