Answer:

The mass and atomic number

Explanation:

There are two numbers that are written in front of the symbol. The mass number (written above) and the atomic number (written below). In mass number is equal to the sum of protons and neutrons, the atomic number is equal to the number of protons in the nucleus. The unstable nuclei are due to excess of protons or neutrons. Radioactive atoms tend to emit them intermittently and randomly.

Answer:

$\boxed{\text{40 mol Al}}$

Explanation:

Al₂O₃ ⟶ 2Al + 3O₂

n/mol: 20

$\text{Moles of Al} = \text{20 mol Al$_{2}$O$_{3}$}\times \dfrac{\text{2 mol Al}}{\text{1 mol Al$_{2}$O$_{3}$}}= \textbf{40 mol Al}\\\text{You can produce }\boxed{\textbf{40 mol Al}}$
