You need 4Al and 3O2 This will give you 2 Al2O3
The balanced equation is: CaCl2 + H2CO3 -> CaCO3 + 2HCl. So, the coefficient needed is 2 in front of HCl to balance the reaction.
Fe2O3 + 2Al ===> Al2O3 + 2FeIn this reaction the number of moles of Al2O3 produced is dependent on the number of moles of Fe2O3 and Al that one starts with. For every 1 mole Fe2O3 and 2 moles Al, one gets 1 moles of Al2O3.
This equation is Al2O3 + 6 HCl = 2 AlCl3 + 3 H2O.
Al2O3 + 3HBr -> Al2Br3 + 3H2O Aluminium tribromide is readily hydrolysed so the hypothetical end product will react further to give a mix of AlBr(OH) compounds. The best preparation is Al metal plus bromine.

This equation is Al2O3 + 6 HCl = 2 AlCl3 + 3 H2O.
The Al and O must balance each other in charge, so it takes 2 Al^3+ for a total of 6+ and it takes 3 O^2- for a total of 6-. Thus, aluminum oxide has the formula of Al2O3
No. If you mean 4Al3O2. And If you mean 4Al + 3O2 ------> AL2O, it is still not balance.
Al2O3 + 3HBr -> Al2Br3 + 3H2O Aluminium tribromide is readily hydrolysed so the hypothetical end product will react further to give a mix of AlBr(OH) compounds. The best preparation is Al metal plus bromine.

The balanced equation is 3 Fe3O4 + 8 Al -> 4 Al2O3 + 9 Fe. Therefore, the coefficient of Fe is 9.
The thermite reaction is:Fe2O3 + 2 Al = 2 Fe + Al2O3
