What coefficient is needed to balance the reaction CaCI2 plus H2CO3 CaCO3 plus HCI?

The balanced equation is: CaCl2 + H2CO3 -> CaCO3 + 2HCl. So, the coefficient needed is 2 in front of HCl to balance the reaction.


How many moles of aluminum oxide (Al2O3) are formed in the reaction Fe2O3 plus 2Al and rarr Al2O3 plus 2Fe?

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.


What is balanced equation of AL2o3 plus HCL?

This equation is Al2O3 + 6 HCl = 2 AlCl3 + 3 H2O.


. Aluminum (Al3 plus ) ions react with oxygen ions (O2-) to form aluminum oxide. What is the correct formula for aluminum oxide?

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


What is the balance the following chemical equation Al2O3 -- Al plus O2?

No. If you mean 4Al3O2. And If you mean 4Al + 3O2 ------> AL2O, it is still not balance.


What is the equation for hydrobromic acid plus aluminum oxide?

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.
