This depends on the reaction; aluminium is trivalent Al(3+).
The coefficient for Al(s) in the balanced equation depends on the specific reaction you are referring to. For example, in the reaction 2Al(s) + 6HCl(aq) → 2AlCl3(aq) + 3H2(g), the coefficient for Al(s) is 2.
the answer is 2 apex

The balanced equation for the decomposition of potassium chlorate (KClO3) is 2 KClO3(s) → 2 KCl(s) + 3 O2(g). Therefore, the coefficient of KClO3 in the balanced equation is 2.
In the balanced equation for the reaction involving solid zinc (Zn(s)), the coefficient for Zn(s) is 1. This means that 1 mole of solid zinc is consumed or produced in the reaction.
The balanced equation is 2KHCO3(s) → K2CO3(s) + H2O(g) + CO2(g). The coefficient of carbon dioxide (CO2) in the balanced equation is 1.
The balanced equation is 4LiNO3(s) -> 4LiNO2(s) + 2O2(g). Therefore, the coefficient of oxygen gas (O2) is 2.
To balance the chemical equation for 3Na + AlCl3 → 3NaCl + Al, you can start by adding a coefficient of 2 in front of AlCl3, giving you 3Na + 2AlCl3 → 3NaCl + Al. Then, you balance the sodium atoms by adding a coefficient of 6 in front of NaCl, resulting in the balanced equation: 3Na + 2AlCl3 → 6NaCl + Al.
The chemical reaction is:SO2 + 2 H2 = 2 H2O + S
The unbalanced equation is: Al(s) + Br2(g) → In order to balance the equation, you need to ensure that the number of atoms of each element is the same on both sides. This balanced equation will help you determine the products.
The balanced chemical equation for the reaction Li + S -> Li2S requires a coefficient of 2 in front of Li and Li2S. Thus, the balanced equation is 2Li + S -> Li2S.
