Question

The following equation 2Al2O3 → 4Al + 3O2 shows that there are 4 atoms of Al and 6 atoms of oxygen in this reaction.

True
False

Answer 1

Looking at the product side:
4Al + 2O3 - that means there's (2x2=4) Al atoms and (2x3=6) O atoms.

However, the equation isn't balanced as it's written...unless you made a typo when posting it.

Answer 2

so true
