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

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 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.
2K(s) + 2H2O(l) = 2KOH(aq) + H2(g) The eq'n is balanced. The coefficients ( molar ratios) in order of the reation eq'n are 2:2:::2:1
The balanced chemical equation for the reaction of aluminum (Al) with water (H2O) can be written as: 2Al(s) + 6H2O(l) → 2Al(OH)3(s) + 3H2(g).
