what is the formula for the salt that forms?

Question

HNO3(aq) + Ba(OH)2(aq) -> 

Answer 1

This is a neutralization reaction and also a double displacement reaction. Therefore, we can predict the products by writing each of our reactants out as the constituent ions that exist when they dissociate in aqueous solution and then switching the anion and cation partners:
HNO₃ dissociates into H+ and NO₃-
Ba(OH)₂ dissociates into Ba²⁺ and OH-

When the cations and ions in solution switch partners, H+ joins with OH- to form water (H₂O), and Ba²⁺ joins with NO₃- to form Ba(NO₃)₂

The barium nitrate product is the salt (ionic compound).

Answer 2

This is an acid/base neutralization which is a form of a double displacement/replacement reaction.  

The salt that forms is barium nitrate.  Can you write the formula for that?
