Write the complete balanced equation for the reaction between aluminum metal (al) and oxygen gas (o2). you do not need to make the subscripts smaller; just write them out as regular numbers. for example: o2.

The reaction between aluminum metal (Al) and oxygen gas (O2) will yield a product called aluminum oxide with the chemical formula, Al2O3. The reaction is shown below,
                           Al + O2 ---> Al2O3
We need to multiply Al by 2 and O2 by 3/2. To eliminate the fraction, multiply both sides of the chemical reaction by 2. These operations give a final answer of,
                          4Al + 3O2 ---> 2Al2O3

Acovalent bond is formed between the two hydrogen bonds
