4 becuase they absorb a little amount
Neutron, neutral subatomic particle that is a constituent of every atomic nucleus except ordinary hydrogen. It has no electric charge and a rest mass equal to 1.67493 × 10−27 kg—marginally greater than that of the proton but nearly 1,839 times greater than that of the electron.
Answer:
- First of all, think the reaction:
4Al + 3O₂ → 2Al₂O₃
- Afterwards, determine the ratio of reactants (4:3)
<u>4</u>Al + <u>3</u>O₂ → 2Al₂O₃
- Convert the mass of Al into moles, by dividing mass / molar mass
48 g / 26.98 g/m = 1.78 mol
- Make a rule of three to determine the moles of O₂
4 mol of Aluminum react with 3 mol of oxygen, so
1.78 mol of Al, will react with (1.78 . 3) / 4 = 1.33 mol of O₂
- Finally, convert the moles in mass like this:
Mol . molar mass = mass → 1.33 mol . 32 g/m = 42.7 grams

Reaction
4Al + 3O₂ → 2Al₂O₃
